A landspout is a type of tornado not associated with a mesocyclone. The term was coined by atmospheric scientist Howard B. Bluestein in 1985. The Glossary of Meteorology defines a landspout as:[A] colloquial expression describing tornadoes occurring with a parent cloud in its growth stage and with its vorticity originating in the boundary layer.The parent cloud does not contain a preexisting mid-level mesocyclone. The landspout was so named because it looks like "a weak Florida Keys waterspout over land."
