What is gust speed?
Is a sudden, brief increase in speed of the wind.

The duration of a gust is usually less than 20 seconds.

What causes gust of wind?
Friction, atmospheric pressure and air warming can all play a part in sudden bursts of wind. Gusts are sudden but short-lived increases in the speed of the wind. They’re often created as wind brushes past buildings, trees or other obstacles, with the friction causing it to slow and then speed up again.
