Answer:
When the wind is blowing, the wind vane points into the wind. ... A cup anemometer is a common tool to measure wind speed. The cups catch the wind and produce pressure difference inside and outside the cup. The pressure difference, along with the force of the wind, causes the cups to rotate.
