How Do Downbursts Form? - National Weather Service
A downburst is created by a column of sinking air that after hitting the surface spreads out in all directions and is capable of producing damaging straight-line winds of over 240 km/h (150 mph), often producing damage similar to, but distinguishable from, that caused by tornadoes. Downburst damage radiates from a central point as the descending column spreads out when hitting the su… WebJan 8, 2024 · When the plume rises high enough, low atmospheric pressure causes its air to cool and cloud to form. In an unstable atmosphere a thunderstorm can develop: pyrocumulonimbus cloud Rain in the cloud evaporates and cools when it comes into contact with dry air, producing a downburst. Lightning may be produced and can ignite new fires. gps wilhelmshaven personalabteilung

The simplest case of isolated microburst is driven by the weight of precipitation causing a downdraft and cooling from evaporation and melting of precipitation in the descending air, which further accelerates the downdraft. gps wilhelmshaven
