A downburst is a localized area of damaging winds caused by air rapidly flowing down and out of a thunderstorm. To create a downburst at the ground, the downward (downdraft) speeds in the thunderstorm must be unusually high, and this downward flowing air must penetrate close to …

2022年7月8日 · A downburst is a strong downdraft that causes an outflow of damaging winds. (NOAA) These damaging wind events can down trees, cause structural damage and be a major threat to planes during takeoffs and landings.

2023年9月4日 · Downbursts (one shown near Burlington, Colo.) cause strong, potentially damaging winds that blow in with little or no warning. Any area that gets thunderstorms can experience these lesser-known...

Downbursts -- a strong downdraft of air that causes an outflow of damaging, straight-line winds at or just above the ground.

What Is a Downburst? Downbursts are powerful wind events that are caused by downward-moving air from a cumulus-type cloud. [1] [2] These strong downdrafts occur when a thunderstorm (or rain shower) can no longer hold the enormous amount of …
