Home > Shopping Tools > Weather Station Glossary of Terms > wind vane (definition) A wind vane is a device that measures the direction of the wind. The wind vane is usually combined with the anemometer. Wind direction is the direction from which the wind is blowing.
A windmill anemometer is a common instrument used at weather stations to obtain the wind speed. A wind vane is used as part of the anemometer to determine the wind's direction. As the wind flows over the windmill, the speed and direction of the wind can be measured with this instrument. Some scientific anemometers use the speed of sound to measure the wind speed more precisely in three dimensions.
