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.
