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.
Size: The microburst downdraft is typically less than 1 mile in diameter as it descends from the cloud base to about 1,000-3,000' above the ground. In the transition zone near the ground, the downdraft changes to a horizontal outflow that can extend to approximately 2 1/2 miles in diameter.
