What does the icon similar to F mean on the weather forecast map?

There is an F in the weather forecast, which is an indicator of the wind. It comes from Feng's Chinese phonetic prefix F.

The bar above represents the size of the wind. The more bars, the stronger the wind. At the same time, the opening direction of F represents the wind direction, that is, from which direction the wind blows.
