Microburst

A microburst is a localized and intense downward burst of wind that occurs during a thunderstorm. It is a small-scale weather phenomenon characterized by a rapid and powerful downdraft of air. Microbursts typically last for a few minutes and have a size of less than 2.5 miles (4 kilometers). When a thunderstorm develops, the storm’s updrafts carry moisture and precipitation high into the cloud. In a microburst, a column of cold air rapidly descends from the cloud, hitting the ground and spreading out horizontally upon impact. Microbursts can produce winds in excess of 100 mph (160 km/h) and cause sudden changes in wind direction and intensity. They can pose a significant threat to aviation, particularly during takeoff and landing, as the sudden change in wind speed and direction can cause loss of control of the aircraft. On the ground, microbursts can cause damage to structures, uproot trees, and create hazardous conditions for people and vehicles. Meteorological instruments, such as Doppler radar, are used to detect and track microbursts, allowing for timely warnings and mitigation efforts.
