What instrument is used to measure wind speed?

An anemometer is the instrument specifically designed to measure wind speed. It typically consists of cups or blades that rotate in the wind; the speed at which they turn correlates with the wind's velocity. This allows meteorologists and other professionals to gather accurate data about wind conditions, which is essential for weather forecasting, understanding climate patterns, and ensuring safety in activities like aviation and sailing.

Hygrometers measure humidity in the air, thermometers measure temperature, and barometers measure atmospheric pressure, none of which relate directly to wind speed measurement. Understanding these different instruments helps clarify the specific role of each in meteorological studies.
