Microbursts occur when the evaporation of rain within a thunderstom cools the air, causing it to lose buoyancy. The air then descends rapidly. When it reaches the ground it sp â¦ reads out, producing strong, sometimes damaging, winds.
The hazard occurs principally when the spatial scale of the downburst is on the order of a runway length. Because of the importance of this scale, Fujita (1985) defined a microburst as a downburst that extends no more than 4 km (2.2 n mi) over the surface.
