Microburst Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
A microburst is a very localized column of sinking air. There are two types of microbursts: wet microbursts and dry microbursts. They go through three stages in their life cycle: the downburst, outburst, and cushion stages. The scale and suddenness of a microburst makes it a great danger to aircraft due to the low-level wind shear caused by its gust front, with several fatal crashes having been attributed to the phenomenon over the past several decades.
