What is a microburst?

A microburst is defined as a powerful downdraft associated with convective precipitation. This phenomenon is characterized by a small-scale weather system that can create extremely strong winds that descend rapidly to the ground, resulting in significant horizontal outflows that can impact an area spanning just a few miles. Microbursts occur in association with thunderstorms and are often short-lived but can be very dangerous for aviation due to the sudden and severe changes in wind speed and direction, which can lead to loss of control of an aircraft during takeoff or landing.

The recognition of microbursts is critical for pilots and drone operators alike, as understanding these wind patterns is essential for ensuring safety when operating in or near stormy conditions. It’s also important to note that these downdrafts can be distinguished from gradual increases in wind speed, calm weather conditions, or specific storm formations. Each of those elements represents different weather phenomena that do not capture the rapid and localized nature of a microburst.
