There is another big distinction we need to make: some anemometers are part of a larger installation - a weather station for example. Anemometers Integrated into Weather Stations In the early days, people had to count the number of rotations of the anemometer to determine wind speed. This means that the data from the anemometer is displayed on a screen. Most wind meters nowadays are digital wind meters. There are many of different types of anemometers: In this section, we will focus on the more common ones. But due to the rotation of the earth, it actually moves clockwise around high-pressure zones and anti-clockwise around low-pressure zones in the northern hemisphere. Air generally wants to move from a zone of high pressure to a zone of low pressure. It is the result of differences in air pressure around the globe. Wind gauges are often present on the top of cranes to monitor whether the wind is not too strong.Paragliders and glider aeroplanes use the data from the anemometer to ensure conditions are safe to fly.Anemometers are used in the sailing and maritime sector to measure wind speed and direction.Physicists use anemometers to study the way gasses move.The invention of the anemometer has greatly improved our knowledge about weather processes.Īnemometers aren't just used in the meteorological field - here are some other use cases: It is thus very important that we can measure wind speed to better understand it and make better weather forecasts.ĭata from weather stations with anemometers and doppler radars with wind speed measuring capabilities are used by big computer models to make weather forecasts. The Importance of the Wind Speed Meterīesides temperature, precipitation and humidity wind is one of the main meteorological parameters. From ultrasonic wind gauges to hot wire anemometers and doppler wind speed meters, which are often used in weather radar to measure the movement of air. But in the last century, there have appeared some more futuristic wind meters. Over the years, the basic anemometer hasn’t changed all that much. However, the wind vane is still by far the most common device for measuring wind direction. With this addition, the speed of the anemometer moves faster or slower depending on whether the tag is moving with or against the wind, and from this the wind direction can be calculated. This was achieved by adding a tag to one of the wind cups. In 1991, Derek Weston developed the three-cup anemometer even further, by added the ability to measure wind direction as well as wind speed. One of the more notable improvements of the wind meter was the invention of the three-cup wind meter by John Patterson in 1926. Over the centuries, it has been improved by a number of different people. by Italian author and architect Leon Battista Alberti. The first wind gauge was created around 1450 A.D. We’ll go into more detail about each of these later. Nowadays anemometer is still the most commonly used term for referring to a wind speed measuring tool, especially in the scientific field.Īnemometers come in different types: handheld anemometers, digital anemometers, wind gauges part of a more advanced home weather station and more. The word anemometer actually originated from the Greek word “anemos”, which translates to “wind”. Since the word anemometer isn’t the easiest to say or spell, wind speed measuring devices are often referred to as a wind gauge or wind speed meter. A Beginner's Guide to Anemometers What is an Anemometer?Īn anemometer is a measurement device that measures wind speed.
