Weather Scope: An Investigative Study of Weather and Climate ... Wind is the horizontal movement of air. The instrument used to measure wind speed is called an anemometer, which is an indicator that will spin in the wind. The anemometer rotates at the same speed as the wind. It gives a direct measure of the speed of the wind.

The main instrument used to measure the speed of the wind is an anemometer. The little cups on this device catch the wind and spin round at different speeds according to the strength of the wind. A recording device is used to count how many times they spin round in a given time.

Anemometer - used to measure wind speed and direction. The wind speed is measured by the propeller. The stronger the wind, the faster the propeller turns. The tail points the instrument into the wind so that we can measure wind direction.
