The wind speed.
depends on the wind at that point
For wind speed: anemometers For wind direction: wind vanes or wind socks
No. They are not winds at all, they are devices. A wind vane indicates wind direction and an anemometer measures wind speed. They only measure winds at a single point, so they are not measuring global winds.
The blades on windmills are designed to catch and harness the force of the wind. When wind blows against the blades, it creates lift and causes them to rotate. The speed of the wind and the design of the blades determine how fast the windmill can spin.
We can use windsocks and wind wanes.
xeg X vtg = Wind in anemometer
You can measure wind force with force transducer.
Anemometer
It is an 'anemometer'
An anemometer is used for measuring the speed of wind,
Dunes are hills or small mountains made of sand and normally form in the desert. They can move because the wind may blow the sand from one point to another.
The opposite of fast wind would be calm or still air.
