Modern tube anemometers use the same principle as in the Dines anemometer, but using a different design. The implementation uses a pitot-static tube, which is a pitot tube with two ports, pitot and static, that is normally used in measuring the airspeed of aircraft. The pitot port measures the dynamic pressure of the open mouth of a tube with ...
An anemoscope c1920s built by the American instrument maker Julien P. Friez & Sons is in the collection of Harvard university was designed to be used as part of an automatic wind recorder alongside a wind speed measuring anemometer. [3] Today anemoscopes are used in meteorological stations, and in transport
Anemometers are also used to measure wind speed and indoor airflow. There are a variety of types, including straight probe anemometers, designed to measure air velocity, differential pressure, temperature, and humidity; rotating vane anemometers, used for measuring air velocity and volumetric flow; and hot-sphere anemometers.
An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [ 1 ] In meteorology , wind speed , or wind flow speed , is a fundamental atmospheric quantity caused by air moving from high to low pressure , usually due to changes ...
The first devices used to measure weather phenomena were the rain gauge, the anemometer and the hygrometer. The 17th century saw the development of the barometer and the Galileo thermometer while the 18th century saw the development of the thermometer with the Fahrenheit and Celsius scales.
Modern instruments used to measure wind speed and direction are called anemoscopes, anemometers and wind vanes. These types of instruments are used by the wind energy industry, both for wind resource assessment and turbine control.

When used with the air temperature, a formula can be used to estimate the height of cumuliform, or convective, clouds. [18] Wind is determined using anemometers and wind vanes, or aerovanes, located a standard 10 metres (33 ft) above ground level (AGL).
