Microburst

A Microburst is a downdraft that moves in a way opposite to a tornado. It is found in thunder storms. And it can be dangerous to an aircraft.

Illustration of a microburst. The air moves in a downward motion until the surface. It then spreads outward in all directions. The wind regime in a microburst is opposite to that of a tornado.

The typical microburst has an average duration of about 15 minutes from the time it is detected until it disappears, its divergence in the first 7 minutes is when it reaches a maximum in wind intensity; the descent occurs below the base of the storm or very close to it, and may have a radius of descent in the first minutes after it hits the ground from about 500 m.
