Wind Direction Measurement Tool

An anemometer measures wind speed.

Wind direction measurement tool.

A wind vane is an instrument that determines the direction from which the wind is blowing. The term is derived from the greek word anemos which means wind and is used to describe any wind speed instrument used in meteorology the first known description of an anemometer was given by leon battista alberti in 1450. 9 55 9. Some scientific anemometers use the speed of sound to measure the wind speed more precisely in three dimensions.

While the above instruments indicate wind direction and provide some rough gauge of wind intensity meteorologists use devices called anemometers to measure wind speed. A wind or weather vane is an instrument that can have different designs such as a horse cockerel pointing arrow and lettering that indicate the different compass. The cups catch the wind turning a dial attached to the instrument.

The most common included with complete home weather stations is the anemometer which typically consists of a rotating vane to measure direction and a shaft with cups attached that spins with the wind to measure its speed.

The same principle is used to measure the dew point using a sling psychrometer a more accurate instrument than the human finger.

By dead down wind. Wind speed and wind direction can be measured with a variety of tools. The direction that the grass falls is the direction the wind is blowing. Another primitive technique for measuring wind direction is to take a pinch of grass and drop it.

An anemometer is a device used for measuring wind speed and direction it is also a common weather station instrument. Two instruments that measure wind direction are the wind or weather vane and the wind sock. These devices indicate the direction from which wind is blowing from. The beaufort scale can also be used to assess wind.

As the wind flows over the windmill the speed and direction of the wind can be measured with this instrument.
