A closer look at how anemometers work, the different types available, and their wide range of uses helps us appreciate their role in daily life. This article shares everything you need to know in simple, clear terms.

What Is an Anemometer?

An anemometer is a device that measures wind speed and direction, and it has become an important tool in weather forecasting, aviation, and construction safety. The science behind measuring wind explains how it captures air movement through spinning cups, vanes, or digital sensors that translate wind force into precise readings. Farmers rely on it to plan irrigation and spraying, while engineers use it to monitor crane operations and site conditions. Its accuracy helps protect lives, equipment, and projects that depend on reliable wind data.

Main Types of Anemometers

Different industries rely on anemometers for accurate wind readings, and over the years, several designs have been created to meet diverse needs. Each type has its strengths and weaknesses; understanding these differences helps people choose the right tool for their work.

Cup Anemometers

Cup anemometers use small cups that spin as wind passes through them. Their design is simple and has been used for decades in weather stations.

Pros: They are reliable, easy to use, and can give consistent readings in different conditions.

Cons: They have moving parts that wear out over time and may give less accurate readings in very light or gusty winds.

Vane or Propeller Anemometers

This type combines a propeller with a vane that helps it face the wind. It is widely used in environmental studies and site monitoring.

Pros: It gives both wind speed and direction at the same time. The design is straightforward and easy to understand.

Cons: The device can struggle in turbulent air and requires regular checking to stay accurate.

Hot-Wire Anemometers

Hot-wire anemometers measure wind speed using a heated wire that cools down when air flows across it. The change in temperature is used to calculate speed.

Pros: They can detect very small changes in air movement and are useful in laboratories.

Cons: They are fragile, expensive, and not well suited for outdoor use in tough conditions.

Ultrasonic Anemometers

These anemometers use sound waves to measure wind without any moving parts.

Pros: They are highly accurate, work well in all directions, and require little maintenance.

Cons: The cost is higher than other types, and performance may be affected by rain or ice.

Pressure Tube (Pitot Tube)

Pitot tubes calculate wind speed by measuring pressure differences as air flows through them.

Pros: They are durable and effective for high-speed measurements, especially in aviation.

Cons: They are less sensitive at low speeds and can be affected by dirt or blockages.

Features to Consider When Choosing One

Selecting the right anemometer is a decision that requires thought, since the tool will influence how reliable your weather readings turn out. A good choice makes the difference between accurate monitoring and guesswork, especially in industries where wind affects safety and productivity. While the options may look similar, their features can vary in ways that matter a lot for real-world use.

Accuracy Range

Accuracy should be the first thing to think about, because the purpose of an anemometer is to measure wind correctly. A small error in readings can affect construction timelines, aviation schedules, or even farming activities. The accuracy range gives you confidence that the numbers you see are dependable, and this saves time and resources.

Wind Speed and Direction Capabilities

Another important feature is the ability to capture both wind speed and direction. Some models only provide speed, but direction can be just as important. For instance, crane operators need both pieces of information to make safe decisions on lifting heavy loads. A device that tracks both allows for better planning and avoids risks.

Durability and Weather Resistance

Anemometers face harsh outdoor conditions, which is why durability and weather resistance should be checked carefully. Rain, dust, and direct sun can shorten the life of a weaker model. Choosing one that has a strong build and can withstand exposure means you will use it reliably for many seasons without constant replacements.

Mounting Type

The way an anemometer is mounted affects its performance. Some are designed for handheld use, while others need to be fixed on poles, cranes, or rooftops. Picking the right mounting type depends on where and how often you plan to use it.

Digital vs. Analog Output

The choice between digital and analog output depends on your needs. Digital devices give clear, easy-to-read displays, while analog models are simpler and often preferred in places where technology support may be limited.

Smart Features

Modern anemometers now come with smart features such as wireless data transfer or mobile connectivity. These allow users to track wind information from a distance, making the process more convenient and timely.

Where and How They’re Used

Anemometers uses span in many areas of work and daily life because they make invisible air movement measurable. Their readings help people make sound decisions, improve safety, and support planning. Understanding where these instruments are installed also shows how much different sectors depend on reliable wind data.

Common Job Site Installations

Construction projects often use anemometers to protect workers and equipment. Tall cranes, scaffolding, and temporary roofing can all become dangerous if winds rise unexpectedly. Contractors place wind meters on cranes and high platforms so operators can check real-time conditions before lifting heavy materials. This simple precaution reduces accidents and gives workers confidence as they go about their tasks.

Use in Weather Stations and Airports

Weather stations rely on accurate wind speed and direction to prepare forecasts that communities trust. Airports depend heavily on these devices since aircraft safety is closely tied to changing wind conditions. Pilots receive detailed updates from air traffic controllers, allowing them to make safe landings and takeoffs. Passengers may not notice, but their smooth travel depends on the small instrument spinning in the wind.

Marine Environments

Ships at sea face powerful winds and shifting currents, making anemometers indispensable on bridges and decks. Mariners depend on them for navigation, sailing adjustments, and storm preparation. Fishing crews, ferry operators, and shipping companies all gain an added layer of safety through these continuous readings.

Why We Measure Wind: Understanding the Purpose of an Anemometer

October 15, 2025/in Wind Power /by Liz W

Wind has always influenced how people live, build, and protect their communities. Yet it remains invisible without the right tools. Anemometers turn this hidden force into data that can be understood and applied in many ways. From keeping work sites safe to supporting climate studies, these devices provide clear, reliable information. Measuring wind is not only about science but also about everyday decision making. This article shows why understanding wind matters and how anemometers help bridge the gap between theory and practical use.

The Fundamental Reason: Wind Is a Force

Wind is not just moving air. It carries energy, creates pressure, and applies force to what it touches. From gentle breezes to strong gusts, this force shapes landscapes, influences climates, and impacts everyday life. With precise measurement, professionals can know not only how fast wind moves but also what direction it takes. This knowledge provides the base for safety, planning, and technology development. Without understood wind force, many sectors would face risk and uncertainty.

The Importance of Wind Measurement in Various Sectors

Measuring wind has become part of daily life in ways many people do not always recognize. Understanding anemometers reveals how knowing wind speed and direction can guide decisions that prevent dangers, save costs, and improve everyday experiences. The uses of anemometers in collecting wind data stretches far beyond the obvious, from crane operators to pilots and from weather experts to coastal planners.

Safety in Construction and Lifting Operations

On construction sites, wind measurement can mean the difference between a safe lift and a dangerous accident. Cranes operate at great heights, and even a slight change in gust speed can shift loads unexpectedly. An employer who invests in quality anemometers does more than follow safety guidelines but they protect workers and their equipment.

Wind data is also used when settling on when to haul large panels or beams. If gust speeds go beyond thresholds, operations pause. This avoids swaying objects that could create chaos on site. While this may cause delays, the cost is nothing compared to potential falling equipment.

Aviation and Airport Operations

Planes must face the elements directly, making wind measurement absolutely essential. At airports, anemometers are connected to control towers that provide pilots with updated data on gust patterns. This helps determine which runway is safe to use and how to approach landing.

When there is a strong crosswind, the country’s largest plane may have to wait, even if every other factor looks clear. That shows how much this invisible force decides the flow of air traffic.

In smaller aviation, such as glider flights, the dependence on wind data is even more pronounced. These pilots use the wind to stay aloft, so they watch speeds closely for every flight.

Weather Forecasting and Storm Tracking

Weather scientists have long relied on wind to reveal the nature of approaching storms. Changes in speed and direction of wind can show when a front is moving in. Even before radar existed, this knowledge helped farmers know when to prepare for rain or potential danger.

Modern forecasting has made this even more precise. Satellite-driven systems use wind data to track hurricanes, allowing authorities to give early warnings. This lead time can prevent mass casualties and give cities chance to move people out of harm’s way.

Even for local forecasts, the wind is a silent indicator of temperature shifts. This is why local news often reports not only how hot or cold it will be but also what the “wind chill” will feel like.

Wind Energy Efficiency

The rise of wind energy has made precise measurement even more valuable. A turbine can produce power only if the wind falls within certain ranges. If the speed is too low, there is no power generation. If it is too high, the blades may have to shut down to protect their structure.

Operators use anemometers to place turbines in the best locations. Long-term wind data is studied to choose sites where averages fall within safe but powerful ranges. This makes investment more profitable and reduces risk.

Energy companies also monitor wind every hour to adjust operations. If gust patterns change, they can switch some units off or reroute power. This flexibility depends entirely on accurate wind data.

Marine and Coastal Safety

The sea has always been governed by wind. Sailors know that the direction and speed decide whether a journey is possible. Even today, modern shipping uses wind data to choose safe routes. This is critical for barges, tankers, and cruise liners.

On the coast, local rescue teams rely on anemometers to warn when conditions are too rough for swimmers or small craft. In many cases, this is the only data they have to stop danger before it happens.

Coastal cities use this information for planning as well. When wind data shows increasing storm trends, engineers prepare for high tides and potential floods. This makes wind measurement part of urban safety, not just marine operations.

Measuring Wind Enhances Planning

Understanding wind helps communities and industries plan effectively. Project managers consider when and how to schedule activities that are sensitive to changing wind. Crane operations, roof installation, and outdoor event setups all depend on predictability. Knowing average and gust speed enables teams to create robust plans that reduce risk and improve efficiency. Even commuter safety could be improved when cities use local wind data to adjust signal timing or warn pedestrians in advance.

Measuring Wind Enables Smarter Design

Architects and engineers use wind data to make decisions that affect building safety and comfort. Wind pressure can influence structural integrity, thermal conditions, and outdoor spaces. Even design of parking lot covers and solar panel sizes depends on the data collected. Correctly integrating wind information saves cost and reduces unexpected problems during and after construction.

Why Precision Matters: Role of Anemometers

Accurate measurement is creating safe spaces for work and life. Anemometers ensure that conditions are quantified precisely, which guides teams in adjusting activities or equipment. Even slight inaccuracies can lead to changes in layout plans, flow of traffic, or safety conditions. The role of anemometers is to translate an invisible force into data that humans can use confidently.

For a company like Bigfoot Crane, reliable measurement is part of safe and smart operation.

Farming and Agriculture

Farmers use anemometers to support daily activities such as spraying crops, irrigation, or managing greenhouses. Wind can carry fertiliser or pesticide to the wrong place, wasting resources and harming other plants. By knowing wind speed and direction, farmers apply products more accurately. Wind data also helps predict drying rates for soil or harvested crops. This leads to better decisions and less risk of loss.

HVAC and Ventilation Testing

HVAC technicians often use anemometers to test airflow in ventilation systems. A building may feel uncomfortable if air does not circulate properly. Using these devices, technicians can measure air speed in ducts and find problems like blockages or leaks. This process helps improve efficiency, lower energy use, and keep residents comfortable. With accurate data, small adjustments can create big savings over time.

Drone Operations and Aerial Photography

Drone pilots rely on anemometers to plan safe flights. Wind affects battery life, control, and stability. A strong gust can push a drone off course or make it crash. For aerial photography, calm wind is necessary to capture clear images. By checking conditions before flight, operators avoid damage and improve their results. This shows how a simple tool can protect expensive equipment and creative work.

Recreational Activities

Ordinary hobbies also benefit from wind measurement. Kite flyers, sailers, and even cyclists use handheld anemometers to test conditions. A kite needs just the right wind to stay up without tearing. For sailers, wind data is part of safety and sport enjoyment. Cyclists may check wind speed to plan routes and manage energy. These small moments show how anemometers bring more prediction and fun to daily life.

Theme Parks and Outdoor Events

Theme parks and outdoor events carry big safety duties when dealing with large crowds. Rides like ferris wheels or zip lines need careful wind checks. Anemometers give staff real-time data so they can close rides when it becomes unsafe. Event planners also track wind to decide on stage setups, tents, or lighting. A sudden gust could lift structures and cause injuries. Using these measuring tools allows safe fun for the public.

The Science Of Measuring Wind & Why Anemometers Matter

August 8, 2025/in Wind Power /by Liz W

Wind has always shaped how people live, travel, and plan their daily activities, yet understanding it fully depends on accurate measurement. Communities rely on clear information about speed and direction, whether for road safety, fishing along the coast, or farming in changing seasons. Anemometers make this possible by turning invisible motion into numbers we can trust. These devices have grown from simple tools into reliable instruments that support weather forecasting, aviation, and energy. Learning how they work shows why wind is more than a passing breeze, but a force that deserves careful attention.

What Is Wind, Scientifically?

Wind is the natural movement of air across the earth’s surface, and scientists describe it as air shifting from areas of high pressure to areas of low pressure. Although we feel wind every day, its formation follows clear physical principles that can be measured and explained. Understanding these principles allows people to appreciate how invisible forces in the atmosphere connect to weather, climate, and daily life.

What Causes Air Pressure Differences?

The sun heats the Earth unevenly, creating temperature differences between land and water and between different regions. Warmer air becomes lighter and rises, while cooler air becomes heavier and sinks. This process creates areas of high and low pressure. Air naturally moves to balance these differences, and that movement is what we call wind.

Other Forces That Shape Wind

Beyond pressure differences, other factors influence the wind’s path and speed. The rotation of the Earth causes the Coriolis effect, which bends the direction of moving air. Friction from mountains, valleys, forests, and buildings also changes wind flow. Together, these forces explain why wind does not always move in a straight line from high to low pressure but twists, slows, or accelerates depending on the environment.

Types of Wind

Winds, such as local, seasonal, and global winds, are grouped in different ways. Local winds may include sea breezes or mountain winds felt in smaller areas. Seasonal winds like monsoons cover larger regions, while global winds shape weather patterns across continents. Each type connects daily experiences to wider climate systems.

Key Wind Parameters

Wind Speed

Understanding wind speed is central to weather and safety decisions. It measures how fast the air is moving across a certain point. Farmers look at wind speed when spraying crops so chemicals do not drift away, while pilots depend on it to plan safe takeoffs and landings. High wind speeds can damage property, while steady moderate winds may support power generation through turbines. Measuring wind speed gives ordinary people and professionals a way to prepare in advance.

Wind Direction

Wind direction tells us where the wind is coming from. This simple detail has a big influence on everyday life. For instance, fishermen check the direction before heading to the lake, while builders use it to guide the placement of structures that need stability. Even households feel the effect as strong winds blowing from certain directions may carry dust or rain into living spaces. Reliable direction readings help communities manage comfort and safety.

Gusts

Gusts describe sudden increases in wind speed that do not last long. They can surprise highway drivers, create hazards for small boats, and even break tree branches. Although short-lived, gusts are measured because of the damage they may cause. Recording them helps authorities issue alerts during storms and gives builders better knowledge of how structures will respond to quick pressure bursts.

Turbulence

Turbulence refers to irregular or chaotic air movement. It often affects aircraft but also influences how wind flows around buildings, mountains, or forests. Engineers consider turbulence when designing tall towers or bridges, while pilots train to handle its effects. Measuring turbulence improves planning and reduces risks linked to sudden shifts in air movement.

Why These Values Matter

Each wind measurement shows what is happening in the air around us. Knowing these values helps protect lives, guides safe travel, and supports industries that depend on the weather. Accurate readings provide confidence that decisions are based on real and reliable information.

How Anemometers Capture Wind Data

The purpose and function of anemometers are to measure wind in ways that provide both speed and direction. Farmers, engineers, and weather experts depend on this data to make daily decisions about safety, planning, and resource use. Each anemometer type is designed to handle specific conditions, which is why there are several models in use today.

Cup and Vane Anemometers

One of the most common devices uses cups mounted on arms that spin as air flows past. The faster the cups rotate, the higher the wind speed. Paired with a vane, which points in the wind blowing direction, this tool provides simple and reliable readings. It is often used in schools, farms, and weather stations because it is affordable and durable.

Ultrasonic Anemometers

Modern technology has introduced ultrasonic models that work without moving parts. They send sound signals between sensors, and the time it takes for the signal to travel reveals the wind’s speed and direction. These instruments are highly accurate and perform well in tough conditions, making them useful in airports, research stations, and coastal monitoring.

Hot-Wire Anemometers

Another option is the hot-wire design, which measures how quickly a heated wire cools when air moves past it. Temperature changes allow the device to calculate airflow with great precision. While more delicate than cup or vane types, hot-wire models are valuable in laboratories and indoor studies.

Why Placement and Calibration Matter

Even the best tool will not provide helpful data if it is poorly positioned. Placing anemometers away from buildings, trees, and other obstacles allows clean airflow to reach the sensors. Regular calibration also keeps readings accurate over time, helping communities and industries rely on the numbers they receive.

The Importance of Accurate Wind Measurement

Accurate wind measurement has become necessary in many industries because people depend on reliable data to make safety, comfort, and efficiency decisions. Communities and businesses gain confidence when they know the conditions around them are being measured carefully. A farmer planning irrigation, a contractor shaping a high-rise, or an engineer testing a turbine all rely on information from well-calibrated instruments.

Safety Across Critical Operations

Air travel, shipping, and road transportation all carry risks that increase when wind is not properly measured. Pilots preparing to land need clear information on gusts and crosswinds, while captains steering vessels on lakes or oceans must judge the strength of winds against currents. Even construction crews benefit when they know the exact wind speed before lifting heavy materials into the air. Reliable data keeps workers safe and reduces the likelihood of accidents.

Designing Structures to Withstand Pressure

Every bridge, tower, and stadium stands against the unseen force of moving air. Engineers cannot afford to guess how much pressure a structure will face. Wind readings shape the design of roofs, glass walls, and tall masts, helping buildings remain stable under pressure. Accurate measurement gives designers the confidence to create structures that last, while giving communities the comfort of safety.

Boosting Energy Efficiency

Renewable energy projects thrive on accurate wind measurement. Turbines must be positioned where airflow is strongest and most consistent. Careful monitoring reduces wasted energy and improves returns for investors while also supporting communities with cleaner power. Reliable data allows engineers to refine placement, increase efficiency, and stretch the benefits of every turning blade.

Factors That Affect Wind Readings

Accurate wind readings depend on a mix of physical and environmental conditions, as well as the way instruments are maintained. Communities, engineers, and forecasters often rely on these measurements to guide safe decisions, so understanding the factors that influence them helps create reliable data.

Physical Obstructions and Surroundings

Tall buildings, trees, and uneven terrain can interrupt wind flow before it reaches the sensor. These obstacles cause turbulence, which makes the readings less reliable. Positioning an anemometer in an open space, ideally above ground level, reduces interference and allows the equipment to capture a clearer picture of the moving air.

Environmental and Thermal Factors

Wind speed and direction are also shaped by temperature differences across land and water. Heat from roads or rooftops can generate small drafts that affect readings, while sudden weather changes may cause sharp shifts. Even altitude plays a role, since thinner air behaves differently at higher levels. These conditions show how closely weather and environment are linked.

Calibration and Sensor Maintenance

Anemometers need care to work well. Dust, corrosion, or loose parts may alter results if left unchecked. Regular calibration and timely servicing keep the sensors reliable, giving communities confidence in the information provided.

Evolving Measurement Technology

Wind measurement has continued to change as technology grows, bringing more accurate and reliable tools. Earlier devices provided basic readings, but modern instruments now give real-time data that can be shared instantly across digital platforms. Many weather stations use advanced sensors that record speed, direction, and sudden shifts with very fine detail. These upgrades support modern weather forecasting, helping aviation, farming, energy, and disaster management professionals respond quickly to changing conditions. What makes this progress even more practical is the way the equipment can be connected to mobile systems, giving communities access to data without delay.

How A Wind Anemometer Shaped Modern Weather Forecasting

July 21, 2025/in Wind Power /by Liz W

The invention of the anemometer gave meteorologists a tool that could measure wind speed and direction accurately, turning weather forecasting into a more precise science. Before this, predictions relied mostly on observation and experience. Reliable wind readings allowed experts to track storms, shifts in air pressure, and changing weather patterns with confidence. Communities, farmers, and pilots could plan ahead and reduce risks. Over time, anemometers became essential in building better forecasting models. This article takes you through everything you need to understand about anemometers and how they transformed how people interpret and respond to weather, making daily life, work, and safety more predictable.

Forecasting Before Anemometers

Before anemometers, predicting the weather relied mostly on observation and experience. People watched cloud movements, felt the wind, and noted changes in temperature or pressure to guess what might happen. These methods worked occasionally but were often unreliable, especially during sudden storms or shifting winds. Farmers, sailors, and travelers faced high risks because accurate information was limited. Communities had little warning about severe weather, which could lead to damage, delays, or danger. Forecasting lacked the precision that modern tools now provide.

Why Observation Alone Wasn’t Enough

Before the introduction of precise wind-measuring tools, people relied heavily on what they could see and feel to anticipate the weather. Farmers, sailors, and outdoor workers often guessed how strong winds were based on cloud movement or the sway of trees. Such methods gave a general sense of changing conditions but failed to capture exact speeds or sudden shifts. Even skilled observers can miss small but significant changes that might impact crops, travel, or safety. Accurate readings became necessary to provide reliable information that communities and professionals could depend on for planning and daily decisions.

Why Wind Speed Changed Everything

Understanding anemometers transformed how people approached weather. Accurate measurements gave farmers, sailors, and planners confidence that their decisions were based on real data rather than guesses. Sudden gusts or calm spells could now be quantified, improving safety and efficiency in daily work. Weather models become more reliable as consistent wind readings allow forecasters to predict storms and rainfall more precisely. Communities started using this information to schedule activities, protect crops, and guide travel, making wind speed a key factor in practical, everyday decisions.

Anemometer Invention and Adoption

The development of the anemometer changed how people understand and measure wind, opening new opportunities for forecasting and planning. The science behind measuring wind made it possible to transform invisible air movement into numbers that could be recorded and compared over time. The adoption of these tools allowed communities and industries to rely on measurable data instead of guesswork, improving safety and decision-making in daily life.

The Cup Anemometer Breakthrough

The cup anemometer offered a simple but effective solution for measuring wind speed. Small cups attached to arms rotated as the wind pushed against them, and the rotation speed translated directly into measurable readings. Observers could now quantify wind consistently instead of estimating it visually. This innovation gained attention quickly because it could be applied in multiple settings, including agriculture, navigation, and early weather studies, offering practical insights that were previously unavailable.

Weather Stations Start Recording Wind

As cup anemometers became more common, weather stations began installing them to collect consistent wind data across regions. Regular recordings allowed forecasters to detect patterns and shifts that were previously missed. Combining observations from several locations gave a clearer picture of local conditions, helping communities and businesses prepare for changing weather. The availability of continuous, accurate readings improved public trust in forecasts and made weather stations central points for reliable information.

Wider Use in National Forecasting

National forecasting services quickly recognized the advantages of widespread anemometer networks. Measuring wind speed and direction at multiple points helped track storms, air pressure shifts, and seasonal variations more accurately. Integrating these measurements into broader systems allowed forecasters to issue timely warnings and guide agriculture, transport, and emergency planning. Anemometers became standard tools in national weather infrastructure, connecting localized observations to a larger understanding of climate behavior and supporting smarter, safer decision-making nationwide.

Impact on Forecast Accuracy

The introduction of anemometers brought a new level of precision to weather forecasting, changing how meteorologists understood wind patterns and their effects. Reliable wind measurements allowed forecasters to predict conditions that once relied on observation and guesswork, creating forecasts that people could trust and act on. These tools opened opportunities for improving storm warnings, daily weather predictions, and long-term climate monitoring across communities and industries.

Stronger Storm Predictions Became Possible

Understanding wind speed and direction at multiple locations gave forecasters the ability to anticipate storms with greater confidence. They could track gusts, shifts in airflow, and pressure changes that often signal approaching severe weather. Accurate readings helped warn communities, farmers, and transport operators ahead of time, allowing preparations that could reduce damage and protect lives. The availability of consistent wind data made storm tracking less uncertain and increased the reliability of forecasts in regions prone to sudden weather changes.

Better Inputs for Weather Models

Anemometer data became an important input for emergent forecasting models. Meteorologists can now use recorded wind speeds and directions to feed simulations and calculations, improving predictions of rainfall, temperature shifts, and storm paths. Patterns that were once invisible now appeared in the data, helping forecasters adjust predictions daily. This allowed for more precise guidance that supported public safety and planning, from aviation to agriculture.

Long-Term Trends Became Easier to Spot

Regular wind measurements made it possible to analyze seasonal and yearly trends. Long-term data revealed shifts in climate patterns and helped identify areas that experients stronger winds or unusual changes. This information supported policy decisions, resource management, and infrastructure planning. Communities benefited from understanding how wind behaves over time, giving them the tools to prepare for both everydaily weather and larger environmental changes.

Role in Modern Forecasting Systems

Anemometers remain at the center of modern forecasting, linking traditional observation with advanced technology to provide accurate wind information. Their measurements help meteorologists, emergency planners, and communities understand daily weather and anticipate changes that could impact safety and livelihoods. Wind data is collected across multiple platforms and integrated into systems that track conditions locally and globally, ensuring forecasts reflect actual atmospheric movement.

Used in Balloons, Satellites, and Drones

Modern meteorology relies on a variety of tools to capture wind data at different heights. Weather balloons carry anemometers into the upper atmosphere to measure air movement that affects storm formation and temperature changes. Sattellites observe wind patterns across continents and oceans, creating a global picture that ground measurements cannot capture. Drones provide flexible options, allowing teams to gather data over specific locations or hard-to-reach areas, giving forecasters information they can trust.

Feeds Data into Global Models

Wind readings collected by instruments feed directly into computational weather models. These models simulate the behavior of air masses, helping meteorologists predict rainfall, temperature shifts, and potential severe weather events. The constant flow of data from land stations, balloons, satellites, and drones ensures models remain accurate and responsive to changing conditions. This integration improves discision-making for aviation, agriculture, and transport sectors.

Supports Public Safety Alerts

Real-time wind monitoring supports early warning systems that protect communities. Sudden gusts, storm intensification, and unusual shifts in wind direction can trigger alerts for schools, hospitals, and local authorities. Accurate measurements allow planners to act quickly, reducing risk and guiding communities to prepare effectively. This ongoing contribution makes anemometers an indispensable tool in maintaining safety across diverse regions.

Localized Forecasting Applications

Accurate wind measurement has transformed how communities respond to changing weather. Local forecasting now allows airports, farms, construction sites, and coastal areas to receive information that is tailored to their conditions. Anemometers placed in strategic locations ensure that decision-makers have real-time data to act quickly and keep people, property, and resources safe.

Wind Alerts at Airports

Air travel depends on careful attention to wind conditions. Airports use anemometers to track gusts and shifts that could affect takeoff and landing. When wind readings reach concerning levels, controllers adjust flight schedules, guide pilots on an approach, and alert ground crews. This constant monitoring reduces delays and maintains safety for passengers and staff.

Wind Guidance for Farms

Farmers rely on wind forecasts to manage crops, spraying schedules, and irrigation. Accurate wind data prevents pesticides from drifting into neighboring fields and helps schedule tasks during calmer periods. Anemometers placed around farms provide detailed measurements that support healthier crops and efficient farm operations.

Safer Construction Sites

High-rise building and crane work require continuous awareness of wind conditions. Sudden gusts can move heavy loads or destabilize equipment. Anemometers installed on towers or mobile platforms allow construction teams to pause operations safely and resume when conditions are stable. Clear, real-time data supports safer work and protects crews.

Coastal and Marine Warnings

Communities along the coast rely on wind monitoring to manage fishing, boating, and shoreline safety. Anemometers detect rising winds that could signal rough seas or approaching storms. Alerts based on these readings help fishermen, port operators, and residents prepare, reducing accidents and protecting livelihoods.

Future Outlook

Wind monitoring technology continues to advance, offering new opportunities for forecasting and safety. Smart anemometers now connect to networks that allow real-time tracking, remote monitoring, and automated alerts. Drones, weather balloons, and coastal sensors provide data in areas that were previously difficult to observe. These innovations make it easier to predict sudden gusts, track storm development, and plan activities that depend on wind conditions.

As systems become more connected, communities, industries, and governments gain tools to protect lives and manage resources more efficiently. Continuous improvement in sensor design, data analysis, and communication ensures that weather forecasts will remain accurate and actionable in the years ahead.

Understanding Wind Anemometers: Definitions, Purpose & Functions

July 1, 2025/in Frontpage Article, Wind Power /by Liz W

Wind plays a quiet role that many people overlook, yet it shapes daily work in construction sites, transport systems, farms, and weather offices. A sudden change in wind can quickly bring new risks, especially in jobs where safety depends on stable conditions such as operating cranes, preparing flights, or following storm patterns. Depending only on eyesight or personal judgment in such cases can be misleading. That is why professionals in different industries turn to instruments that measure the wind and give them clear information they can trust.

Anemometers are the tools built for this purpose. They collect real-time data and translate shifting air into numbers that can guide decisions. Some models show wind speed alone while others also give the direction of flow. The readings help teams reduce guesswork, plan ahead, and keep people safe. These devices are now common on construction projects, weather stations, and even in the hands of field workers who move from site to site.

This guide will explain anemometers, their function, where they are applied, and why they have become part of everyday planning.

What an Anemometer Does

An anemometer is a tool that shows how fast the wind is moving. Instead of guessing whether the wind is strong or light, it gives a clear reading. This makes it useful in many areas of work.

In airports, wind speed is checked to guide planes during takeoff and landing. On construction sites, workers use it to determine whether it is safe to run cranes or lifts. Farmers also look at wind readings before spraying chemicals since the wind can carry them to the wrong place. Even in energy projects, wind speed is measured to improve how turbines produce power.

Different types of anemometers work differently. Some have cups or small blades that spin when the wind blows, while others use sensors that record changes in air movement. The science behind measuring wind involves how instruments detect air movement and convert it into quantifiable data. Different designs accomplish this in various ways, depending on environmental conditions and the desired level of accuracy.

Cup Anemometers

These are easy to spot because of their cup-like design. Usually, three or four cups are attached to short arms. When the wind passes, the cups rotate, and the faster they turn, the stronger the wind. This type is often fixed on rooftops or at permanent weather stations.

Vane Anemometers

This type works like a tiny wind turbine. A fan blade spins whenever air moves through it. Many portable wind meters are built this way. It can also point out the wind’s direction if combined with a wind vane. People who fly drones and technicians working on air systems often rely on this style.

Hot-Wire Anemometers

Instead of moving parts, this design uses a very thin wire that is heated using electricity. When air flows across the wire, it cools it down. The cooling rate tells how fast the wind is moving. These are mostly used for controlled studies inside buildings, such as checking airflow in vents and ducts.

Ultrasonic Anemometers

This type has sensors that send sound signals to each other. When the wind blows between them, it changes the time the sound travels. From this, both speed and direction can be calculated. Because there are no moving parts, ultrasonic models are valued in places where reliability and less maintenance are needed.

Pitot Tube (Pressure-Based) Anemometers

A pitot tube works by comparing pressure levels. It measures the difference between air that is still and air rushing into the tube. These readings help determine wind speed. Such devices are mostly used in aircraft and also in wind tunnel research.

Why We Measure Wind

Understanding wind is part of keeping people, projects, and equipment safe. It affects how buildings are designed, how machines are used, and how we prepare for changing conditions. Anemometers make this possible by giving correct readings of speed and direction, allowing teams to plan their work with confidence.

Safety on Construction Sites and Crane Operations

Wind is one of the biggest risks on construction sites. A sudden gust can cause a suspended load to swing or even put scaffolding at risk of collapse. Cranes are especially sensitive since strong winds can push them off balance. That is why many sites place anemometers on cranes or tall structures. Workers check the readings and pause operations when the wind reaches unsafe levels. This prevents accidents and protects both workers and machines.

Weather Forecasting and Storm Tracking

Wind patterns are among the main signals meteorologists use when predicting weather. A change in speed or direction can point to rain, storms, or a drop in temperature. Because of this, reliable wind readings are fed into forecast models that people and industries depend on. Farmers, pilots, and even households use these forecasts to plan their activities well in advance.

Designing Structures That Can Handle the Wind

Every structure interacts with wind. Tall buildings, bridges, and even housing estates face pressure from moving air. Engineers rely on wind data to understand how much force a building will face in its location. This knowledge guides the choice of building materials, the shape of the design, and the placement of windows or openings for airflow. Using accurate measurements makes it possible to create safe, durable, and comfortable spaces.

Improving Wind Energy Efficiency

Energy production from wind depends on the flow of air. Before a turbine is installed, experts use anemometers to find out if a site has the right conditions. Once turbines are running, ongoing wind measurements help track performance and improve efficiency. Even small shifts in wind strength can affect how much electricity is generated. Having good data supports planning and helps the energy sector supply power reliably.

How Anemometers Work

The purpose of an anemometer is to convert moving air into measurable data. Although each type operates on a different principle, they all fulfill the same role: turning wind speed and direction into information we can track and understand.

Cup Anemometers

One of the oldest designs is the cup anemometer. Small cups are fixed on arms that rotate around a center. When the wind blows, the cups spin faster depending on the strength of the flow. A sensor tracks the number of turns, which is then used to calculate wind speed. These are often mounted on weather stations, poles, and building rooftops.

Vane Anemometers

Vane anemometers use a fan-like rotor to pick up moving air. As wind flows through, the blades spin, and the spin rate indicates how fast the wind goes. Many models also come with a tail section that keeps the device facing into the wind, making it useful for checking both speed and direction. They are often used in fieldwork since they are portable and easy to handle.

Hot-Wire Anemometers

Instead of moving parts, hot-wire anemometers work with heat. A very thin wire is heated using electricity; when air moves across it, it cools down. Stronger wind cools it more quickly. The instrument monitors this cooling process to calculate the speed of air. These tools are normally found in indoor environments like ventilation testing, laboratories, or controlled airflow studies.

Ultrasonic Anemometers

Ultrasontic models depend on sound thander than motion. They send high-frequency sound pulses between sensors. When wind passes through, it alters how long the sound takes to travel from one sensor to the other. By checking these time changes, the device can give readings for both speed and direction. Since they have no moving parts, they are often chosen for areas where reliability and low maintenance are important.

Pitot Tube Anemometers

A pitot tube works by detecting pressure differences. Wind enters a narrow tube, which builds up pressure inside. This is compared against the still air pressure, and the difference is converted into a wind speed reading. These are the same instruments commonly fitted in aircraft systems and research wind tunnels.

Industry Applications

The value of anemometers is seen in how they make everyday decisions safer and smarter across industries. Turning invisible wind into data illustrates how an anemometer changed modern weather forecasting, allowing people to predict conditions more accurately. While their influence is widespread, their ability to provide consistent readings is what makes them reliable tools in fields as diverse as construction, energy, aviation, weather studies, and marine operations.

Meteorology and Forecasting

Modern forecasting depends on accurate wind readings. Anemometers capture both speed and direction, and this data feeds into computer models that predict rainfall, storms, and shifts in temperature. Farmers rely on these forecasts to plan planting or harvesting, while families use them to prepare for severe weather. Tracking wind has changed forecasting from guesswork to dependable science.

Marine and Offshore Use

On the sea, wind can decide how safe a journey is. Ships adjust their routes and fuel use depending on how the wind behaves, while offshore rigs monitor gusts that might interfere with lifting equipment or crew movements. Real-time measurements reduce the risk of sudden surprises at sea and allow smoother planning for long voyages or daily operations.

Construction and Crane Operations

Heavy lifting at construction sites depends on steady conditions. Strong winds can sway cranes or push materials off balance, putting workers and equipment at risk. When anemometers are fitted on cranes or rooftops, they give instant feedback that allows site managers to stop work before conditions become unsafe. This simple tool often prevents accidents and delays that would otherwise be costly.

Wind Energy Monitoring

Energy companies look to wind turbines as a dependable source of power, but turbines only perform well when positioned correctly. Anemometers mounted at turbine height monitor airflow around the clock. The readings help operators adjust blade angles and track output. Over time, this data also guides where to build new turbines, making sure each site produces as much energy as possible.

Aviation Safety and Flight Management

Flying safely requires constant awareness of wind. At airports, anemometers along the runway guide air traffic controllers as they direct takeoffs and landings. Pilots use the information to plan weight distribution, adjust routes, and manage fuel consumption while in the air. Without steady wind data, even routine flights would face unnecessary risks. Anemometers play a quiet but important role in keeping air travel safe and efficient.

Choosing the Right Anemometer

The right device depends on the type of work it will support. While all anemometers measure wind, not every model is built for the same setting. A unit fixed on a tower may suit a permanent site, while a compact handheld model works better for mobile inspections. Thinking about the working environment before purchase helps avoid the wrong choice.

Accuracy and Reliability

Wind readings are only useful if they are correct. In fields such as aviation or lifting operations, small mistakes in data can expose teams to serious risks. A anemometer that produces steady and trustworthy results allows workers to act with confidence and reduces dowtime caused by false readings.

Durability and Weather Resistance

Outdoor equipment has to withstand tough conditions. Anemometers that last are usually made with strong casings, sealed parts, and non-rusting materials. These features protect against rain, dust, and sun, making the tool a dependable partner through different seasons instead of a device that fails after a few months.

Mounting Type and Use Case

The style to choose depends on where and how the anemometer will be used. Permanent fixtures are best for rooftops, masts, and construction machinery. Portable models are lighter and easier to move, suitable for teams that work across different sites or need a tool that can be carried during inspections.

Useful Features That Support the Job

Modern anemometers often come with functions that save time and improve safety. Instant alerts can notify workers when wind speeds shift suddenly. Data logging lets teams study patterns instead of relying on single readings. Clear displays also make it easier to read values quickly while on site.

Maintenance & Calibration

Anemometers stay reliable only when they are cared for. Outdoor units often face dust, rain, and heat, which can block sensors or slow moving parts. A simple routine of cleaning and inspection helps prevent small issues from turning into failures. Even in calmer settings like offices or labs, occasional checks make sure the device keeps performing as expected.

Calibration Should Match Use and Environment

Not every site demands the same calibration schedule. A meter on a crane, exposed to vibration and changing weather, may need attention more often than one in a quiet indoor space. Following the manufacturer’s guide is a good start, but many busy sites benefit from shorter intervals, such as twice a year. Regular calibration keeps readings dependable and avoids costly mistakes caused by drift.

Knowing When to Replace or Upgrade

Every tool has a working life. Signs like slower spinning cups, fading displays, or sensors that lose precision show it might be time for change. Replacing worn parts can extend service, but in many cases, upgrading to a new model saves time and adds useful features. Modern units often bring better durability, easier maintenance, and functions that improve daily operations.

Future Trends in Wind Monitoring

Wind monitoring is becoming smarter and more connected. The latest anemometers are no longer just about recording speed. Many now come with sensors that feed information into digital platforms through IoT technology. This means readings can reach devices like tablets or control centers in real time, giving site teams quick access to data whenever they need it.

Predictive Safety and Early Warnings

New systems are focusing on preventing risks instead of only responding to them. By studying patterns in wind changes, some devices can forecast unsafe conditions before they occur. Crane operators and project managers can receive early alerts that help them pause work or adjust plans before high winds put people or equipment in danger.

Fully Connected Worksites

Wind data is now being linked with bigger site management tools. Platforms such as BIM or fleet tracking software are starting to include anemometer data as part of their operations. This integration allows teams to manage schedules, safety, and planning with wind conditions already factored in, making work smoother and safer across the board.

High above KC’s changing skyline, crane operators build downtown’s revitalization

August 9, 2017/in Construction, Cranes, News, Outdoor Events, Wind Power /by Jason Pohl

Perched high above a Children’s Mercy Hospital construction site, Carl Potter gently moves his left wrist and the 100-plus-foot tower crane rumbles to the right.

A push of his wrist sends the crane’s hook to the ground, where dozens of construction workers wait to attach a cement bucket to the crane’s rigging. They look like toy soldiers from this vantage point.

One of the four walkie-talkies used to communicate with the workers goes off, and he’s on to the next pick. Sometimes he eyes the drop and sometimes can’t see his work at all — relying on radio signals to navigate.

“It’s constant. There’s a tentative schedule, but I don’t eat lunch, I don’t have time,” says Potter, a tower crane operator for about 17 years.

As one of about 4,500 heavy machine operators in the Operating Engineers Local 101 union, Potter has been busy handling downtown Kansas City’s construction boom.

From his operator’s chair, Potter has a breathtaking view of downtown — a skyline crane operators have forged in the last decade — the Sprint Center, Kauffman Center for the Performing Arts and the current construction of the city’s Two Light luxury apartments.

“Downtown’s growth has been the single most important thing that has happened to the construction industry,” said Jeff Holt, director of operations for Wilkerson Crane rentals, which owns cranes and provides operators. “Ten years ago you didn’t go downtown for nothing, and as an operator, the pride of driving downtown and seeing the things you’ve built, being a part of that change, it’s incredible.”

Potter, 41, of Lee’s Summit, has been up since 3:30 a.m. and has been overlooking the parking garage construction site inside the closet-sized cockpit since 4:30 a.m..

There’s a honey bun, oatmeal cream pie and a few empty energy drink cans in a neat row near his left arm rest. Underneath, a small cabinet door conceals a few water bottles filled with urine — it would be a waste of time to make the 10-minute climb down to use the restroom.

There’s an AM/FM radio built into the crane’s dashboard, but Potter doesn’t use it, opting for complete concentration during his typical 11-hour shifts. Potter tries to minimize distractions in a construction industry that accounts for more than 4,500 deaths annually, according to the Occupational Safety and Health Administration. He combines this discipline with more than 4,000 hours of required training by the union’s certification program.

Learning how

About 30 miles north in Weston, Stoney Cox stands on top of a 100-foot tower crane.

Cox, administrator of the union’s apprenticeship program, surveys the 220-acre training facility and casually leans over the railing. The facility is one of the largest in the country with a diverse landscape of hills and trees.

The Operating Engineers represent workers who use heavy machines, which include large dirt excavators, rollers, bulldozers and various cranes. The facility has more than 50 machines on the property to practice on. The international union often hosts conferences and training sessions on the property.

“Apprentices will take these cranes entirely apart almost a dozen times and learn every part of the machine before they even sit in an operator’s chair,” Cox says.

The three-year program requires 4,000 hours of training, including time in the facility’s classrooms and in the field working as an oiler. An oiler acts as an assistant to the large machine operators, maintaining the equipment, and in turn, the operator trains the apprentice on the job.

Nationally, middle-skill jobs, which require education beyond high school but not a four-year degree, make up the largest part of the labor market in the United States. In both Missouri and Kansas, there aren’t enough skilled laborers to fill the jobs, according to the National Skills Coalition.

Local 101 president Michael Charlton says the union has had a steady flow of apprentices the last few years to meet the area’s growing demand. They’ve struggled to recruit in the past, but Charlton says a more aggressive online advertising campaign and career fairs have boosted numbers.

“There’s zero cost to be an apprentice,” Cox said. “We use that a lot when we go to career fairs. Then parents come in and are asking, ‘You telling me little Johnny doesn’t have to pay for this?’ He pays nothing.”

At the same time, college is getting more expensive. The average four-year college student graduates with more than $30,000 in debt, according to the Institute of College Access and Success. As an apprentice, workers can earn close to $40,000 a year and can make $70,000 to $100,000 by the time they are journeymen.

Holt says high- school students aren’t exposed to certificate programs and trade schools. Often, he says, construction work is looked down upon.

“There’s a definite push that you need a college education to do anything,” Holt said. “This is a great living; I have done this since I was 18. I didn’t go to college — college wasn’t for me — and there are a lot of kids like that out there.”

“I know I can do my job”

Monica Confer always felt restless in a classroom. She stopped going to high school when she was 14 and opted for a GED certificate instead.

She held a bunch of jobs as a teenager and in her early 20s, running forklifts for warehouses and spending time in an auction yard. Confer had her son at 19, and the jobs weren’t cutting it.

“I needed better benefits for my son,” said Confer, 38, of Kansas City. “I could not afford insurance making less than $10 an hour.”

College wasn’t an option. She grew up in a union family, and her father’s friend recommended she apply to the Operating Engineers. She started as an apprentice in 2002.

Sometimes when she arrives at a new job site, she said, guys ask if she is the oiler; they’re surprised to see a woman in the operator’s chair.

“I’ve never had any big problems,” Confer said. “I think it used to bother me but I don’t even care anymore. Whatever, I know I can do my job.”

Charlton remembers a time when there were no women in Local 101 but says women now make up of about 20 percent of the workforce.

In 2014, the Bureau of Labor Statistics reported 9.8 million people working in the construction industry. Of those, 872,000 of them, or 8.9 percent, were women.

Confer admits a level of paranoia about safety on the job. She typically wakes up by 4 a.m. to get to a job site about an hour early, especially at a new site. She goes through 20 minutes of safety inspections and gets to know every inch of the machine.

She has gotten home, sat on her couch and panicked about whether she had set the crane’s brake. She’ll climb back into her SUV and drive back to the construction site to double check.

“Everybody sees the crane collapses on the news. I have never been on a job when there’s been a crane accident,” Confer said. “If something were to happen and you hadn’t done your safety checks, that’s your conscience, legalities aside.”

Unstable ground conditions, high gusts of wind and operator error are the leading causes of crane accidents, Charlton said. And with more cranes among denser populations downtown there’s less room for error.

Boom town

Tommy Wilson, an urban planner for the Downtown Council of Kansas City, marks the beginning of the city’s revitalization around 2003 with the approval and planning of the Power & Light District. The boom includes construction of the the Sprint Center, H&R Block’s headquarters and new residential spaces. In 10 years, close to $6.5 billion dollars has been invested into downtown.

Wilson says the streetcar’s construction sparked a second wave of development in 2013, with an additional $1 billion invested along the Main Street route. “Our next step and goal is to make the redevelopment sustainable. Sustainability is having a good residential population that calls this place home,” Wilson says.

He says around 24,500 people live downtown, and that number will grow to nearly 30,000 by 2020.

As more people move downtown, more retail and additional office spaces follow, attracting additional residents — it’s a cycle of growth that Wilson projects will continue.

“This downtown revitalization isn’t just a fun phase we are going through” Wilson says. “We want this growth to continue for decades to come.”

Exploring the weather hazards behind 5 deadly, notorious plane crashes

July 26, 2017/in Outdoor Events, Weather, Wind Power /by Jason Pohl

Though many unfortunate factors can result in aviation accidents, among an aircraft’s greatest threats are ice, fog and wind shear, which is rapidly changing wind currents.

A National Transportation Safety Board (NTSB) study shows more than two-thirds of all weather-related general aviation crashes have been fatal.

Microbursts: An invisible killer

According to NASA, phenomena known as microbursts, which are short-lived downdrafts that are often present during thunderstorms, can create forceful and dangerous wind shear.

The National Weather Service (NWS) defines downdrafts as small-scale columns of air that rapidly sink toward the ground, usually accompanied by rain.

Planes are particularly vulnerable during takeoff and landing.

On July 9, 1982, a microburst brought down Pan Am flight 759 from New Orleans International Airport, killing 153 people.

It caused decreasing headwind and downdraft, which the pilot would have struggled to recognize in time, the NTSB official report concluded.

A microburst also caused Delta Airlines flight 191 to crash in Dallas on Aug. 2, 1985.

While attempting to pass through rain beneath a storm, it crashed 6,300 feet north of its runway at Dallas/Fort Worth International Airport, hitting and killing a driver, according to the NTSB report.

Lack of training and real-time wind shear hazard information contributed to the deaths of 134 passengers, the NTSB reported.

Between 1970 and 1985, low-altitude wind shear caused crashes that killed 575 people, according to the NTSB.

In 1988, the Federal Aviation Administration (FAA) mandated that commercial aircraft be equipped with wind shear detection systems by 1993.

“Wind shear accidents have become very rare in recent years thanks to better forecasting tools, pilot training and sophisticated onboard warning systems,” said Patrick Smith, an active airline pilot and air travel blogger.

“But the phenomena is still potentially dangerous,” he said.

Fatal fog risk

Foggy conditions are also often deadly for pilots, according to the Flight Safety Foundation.

They occur when water droplets suspend in the air at the Earth’s surface.

Hazards arise when visibility is reduced to a quarter of a mile or less, according to the National Oceanic and Atmospheric Association (NOAA).

In 1977, upon takeoff from Los Rodeos Airport in the Canary Islands, KLM flight 4805 sheared the top off Pan Am flight 1736, which shared the same runway.

According to the official report, heavy fog enveloping the airport prevented both flight crews from spotting each other until it was too late.

It was the deadliest fog-related crash in history, killing 574 people.

The control tower was unable to see the two planes, and at the time, the Los Rodeos Airport had no ground tracking radar.

A number of other factors, including poor communication, also contributed.

“The ultimate cause was the KLM pilot initiating takeoff without clearance and disregarding his crew’s inquiries about whether they were cleared for takeoff,” said aviation consultant Jim Goldfuss.

“Airport surveillance radars as well as taxiway and runway lighting technology has adapted to prevent accidents like this,” he said.

Icy aircraft dangers

Ice-covered planes pose another potentially deadly risk.

In 1982, 78 people perished when Air Florida flight 90 smashed into a bridge, collapsing into the icy Potomac River shortly after takeoff.

“Parked at the terminal, an aircraft collects precipitation the way your car does — via snowfall, sleet, freezing rain or frost,” Smith said.

Icing can disrupt airflow around a wing, which robs a plane of lift, he said.

Flight 90 departed Washington National Airport with icy wings during moderate to heavy snowfall, according to the crash report.

“[This] changes the wing’s shape, which can result in a stall at a higher-than-expected speed,” said Goldfuss.

The NTSB reported that the flight crew’s failure to use engine anti-ice before takeoff and their decision to depart with ice on the plane contributed to the crash.

A decade later, US Air flight 405 departed New York’s LaGuardia Airport, also with icy wings.

The plane lost lift just after leaving the runway and crashed into a nearby bay, killing 27.

It had been previously de-iced.

However, the NTSB concluded that the flight crew’s failure to check for ice accumulation on the wings 35 minutes after exposure to precipitation was a contributing factor to the crash, which occurred more than 20 years ago.

“We’ve come a long way with it as far as anti-icing and de-icing, as well as improved crew training and how to deal with icing conditions,” said Smith.

“Those [crashes] were tough lessons to learn,” said Smith, “but airliner crashes brought on by icing have become exceptionally rare.”

LAHORE: Around 13 people died and over 100 were injured in separate incidents after rain and windstorms lashed several cities across Punjab on Saturday.

Several cities, including Lahore, Faisalabad, Sialkot, Gujranwala, Kasur, Bahawalnagar, Multan, Chichawatni and Lodhran received light and heavy rain on Saturday, along with gusty winds.

Six people died and around 60 were injured in Bahawalnagar alone, after thunderstorm hit the city in southern Punjab. Strong winds knocked down billboards and brought down roofs and walls of various structures.

An emergency was declared at the District Headquarters Hospital. Among the deceased was a 10-year-old girl while the injured too included five children and 10 women.

In Chichawatni, Sahiwal, various rain and wind-related incidents caused the deaths of three people, including two children and led to injuries to around 22 people.

In Lahore, a man died and three others were wounded after roof of a house collapsed in Chauhang area. A woman died in a similar incident in Faisalabad in which one was also injured.

In Multan, a man died of electrocution while 19 were injured in rain-related accidents. Similarly, in Rajanpur, a father and son were killed after being electrocuted.

Over 28 people were reported injured in different incidents in Multan and Lodhran as well.

The rainfall resulted in tripping of several feeders of Lahore Electric Supply Company (Lesco), suspending power supply to a large part of the region.

The cities affected by subsequent power breakdown included Lahore, Sheikhupura, Kasur and Nankana Sahib.

Meanwhile, several districts of Khyber Pakhtunkhwa as well as Murree and surrounding areas received heavy rain and hail.
