microburst

A convective downdraft (downburst) that covers an area less than 4 km along a side with peak winds that last 2–5 minutes.

Differential velocity across the divergence center is greater than 10 m s−1. The strong wind shears associated with a microburst can result in aircraft accidents. Microbursts can be wet (contain rain) or dry.
