What instrument do weathermen use to tell the wind and air speed


Barry's Response - The first thing they use is called an anemometer. It usually has four small cups on sticks that catch the wind and spin in a circle, faster with stronger winds. Wind speed is derived from the speed of rotation of this propeller-like device.

A weather vane points the wind and air flow direction. In this way, it acts like a flag.

One other interesting device is the windsock, a conical tube that indicates both wind speed and direction in a qualitative fashion. You may have seen one of these near an airport runway.

I thought it was to short but very interesting. I did not know about anemometer. It needed more information. I would not go explore more information.

Can I get more details?

Good answer but I'd like more details - how do they use this device? Also, can I make one at home for myself and if so, how would I do that?
