The word tornado derives from the Spanish word ?tornado?, meaning "thunderstorm", which in turn was derived from the Latin word ?tonare?, meaning, "To thunder". People also refer to tornadoes as twister, and the colloquial term cyclone.A tornado is an atmospheric phenomenon associated with very rough weather. The Encyclopedia of Meteorology defines it as "a violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, but not always visible as a funnel cloud". Thus, tornadoes refer to a vortex of wind in contact with both the ground and cloud base, and formed before the water vapor present in such winds condense into clouds. Tornadoes form from violent thunderstorms, usually the super cell variety of the thunderstorm and cause widespread destruction in the path it swirls.
