How is wind direction measured?

Answer 1

The simplest directional indicator is the "wind vane", which uses air pressure on its "tail" to turn the nose in the direction from which the wind is coming.

The wind direction is measured with wind vanes or wind socks.

The wind speed is measured with an anemometer, although both wind socks and flags can provide a general range for wind velocity.
Wind direction is measured by the direction from where it originates. Wind shock and wind vane is used to measure the wind direction.

Answer 2

Wind direction is typically measured using a wind vane, also known as a weather vane. These instruments align themselves with the wind, pointing in the direction from which it is coming. Meteorologists also use windsocks, which are shaped like a tube open at one end, to visually indicate wind direction by the way they blow.
