What does an anemometer measure?

• A. Air temperature
• B. Wind speed
• C. Humidity levels
• D. Atmospheric pressure

Answer: (B)

An anemometer is a specific instrument designed to measure wind speed. It functions by using various methods, such as rotating cups or blades, that respond to wind flow. As the wind blows, it causes the anemometer to rotate at a rate proportional to the wind speed, allowing for easy measurement. This information is vital in meteorology for weather forecasting, aviation safety, and various engineering applications. The other options refer to different instruments: thermometers measure air temperature, hygrometers assess humidity levels, and barometers are used to measure atmospheric pressure. Each of these tools serves a distinct purpose, highlighting the specialized nature of anemometers in capturing wind dynamics.
