An example of a supercell.

A supercell is a strong type of thunderstorm with a thick, rotating updraft (a mesocyclone).[1] Supercell thunderstorms are the largest, most dangerous type of thunderstorms.[source?] There are really only two types of thunderstorms: supercell and ordinary, but some have four classifications: single-cell, multi-cell, squall line, and supercell.
