Which instrument measures wind speed?

Which instrument measures wind speed?

• A. Thermometer
• B. Barometer
• C. Rain gauge
• D. Anemometer

Answer: (D)

Measuring wind speed is about figuring out how fast air is moving past a point. The instrument designed for that is the anemometer. In the common cup style, wind pushes the cups and makes the device spin; the faster it turns, the stronger the wind. The rotation rate is then translated into a wind-speed value, usually in meters per second or kilometers per hour. This is different from a thermometer, which measures how hot or cold it is; a barometer, which tells air pressure; and a rain gauge, which collects and measures rainfall. There are other forms of wind sensors too, like vane or sonic types, but all are used to determine wind speed. So, the instrument that measures wind speed is the anemometer.
