How wind speed is measured

Posted by on Saturday, September 24, 2016

Wind speed is measured using an anemometer.

An anemometer looks like a weather vane, but instead of measuring which direction the wind is blowing with pointers, it has four cups so that it can more accurately measure wind speed.

Quite simply it works like this: the faster the wind, the faster the cups rotate. The speed of the rotating cups is measured by a speedometer.

Wind has both speed and direction.
