What can downdrafts in microbursts exceed in feet per minute?

Downdrafts in microbursts can indeed exceed 6000 feet per minute. A microburst is a potent and localized downdraft that occurs within a thunderstorm and is characterized by strong, rapidly descending air. When this downdraft strikes the ground, it can spread out in all directions, creating hazardous conditions for aircraft, especially during takeoff and landing.

The intensity of microbursts is notable; they can produce extremely high rates of descent that significantly exceed those typical of standard downdrafts found in larger storm systems. This rapid descent can lead to sudden and severe changes in wind speed and direction, making microbursts particularly dangerous for pilots. Understanding that these downdrafts can exceed such excessive rates helps in the awareness and mitigation of risks associated with flying in areas prone to microbursts.
