Anemometer

Definition

An anemometer is a meteorological instrument used to measure wind speed and, in some cases, wind direction. By providing critical data about wind conditions, it plays a vital role in understanding atmospheric dynamics and influences various natural phenomena including weather patterns and storm behavior.

5 Must Know Facts For Your Next Test
