What is the meteorological phenomenon of a rapid descent of the downdraft from a thunderstorm?

Arab Weather - The meteorological phenomenon that represents a rapid descent of the downdraft from a thunderstorm is known as a "downdraft" or "microburst". This phenomenon occurs when a stream of cold, fast air descends from a thunderstorm to the Earth's surface, then spreads rapidly in all directions. Downdrafts can have powerful and destructive effects, such as strong winds that can reach speeds of more than 160 kilometers per hour, causing damage to infrastructure, trees, buildings, and even aircraft that are close to the ground.
