A microburst typically occurs over what horizontal distance?

Explanation:
A microburst is a very small, intense downdraft that hits the ground and spreads outward in a narrow area. Because of its compact size, the damaging winds and wind shear it creates are confined to a short horizontal distance—about one nautical mile or less. Larger downbursts affect far wider areas, so the other distances listed belong to macrobursts or broader gust fronts, not microbursts. This small footprint is why microbursts can surprise pilots during takeoff or landing, as strong surface winds can develop and vanish within a brief arc of the runway.
