Microbursts

The arrows in this sketch represent the movement of air in a microburst, a concentrated intense downdraft formed by extraordinary evaporative cooling that creates an outward wind burst at the surface. If you could see it leave the cloud and strike the ground, it might resemble a narrow stream of water “splashing” into a sink. Because of the extremely abrupt changes in wind direction within microbursts, they are a threat to aircraft during landings and takeoffs.
