A hemispherical-cup anemometer of the type invented in 1846 by John Thomas Romney Robinson. In meteorology, an anemometer (from Ancient Greek άνεμος (ánemos) 'wind' and μέτρον (métron) 'measure') is a device that measures wind speed and direction. It is a common instrument used in weather stations.
Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction
Devices used to measure weather phenomena in the mid-20th century 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.
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 same principle is used to measure the dew point using a sling psychrometer (a more accurate instrument than the human finger). Another primitive technique for measuring wind direction is to take a pinch of grass and drop it; the direction that the grass falls is the direction the wind is blowing.
The side of the vehicle sustained damage, and the anemometer masts used to measure wind speed were bent at a 45-degree angle. The anemometer itself was blown off and taken away by the tornado. The ...
Anemometer, weather vane, anemoscope A windsock (a wind cone or wind sleeve) is a conical textile tube that resembles a giant sock . It can be used as a basic indicator of wind speed and direction , or as decoration.
