What is a Tornado?

A tornado is a whirlwind of extremely violent winds, originating at the base of a storm cloud (cumulonimbus) when wind shear conditions are favorable in the lower atmosphere. Very low tornadoes can also develop under clouds of showers (cumulus congestus).



Where do tornadoes come from?

It is widely agreed upon that more than one location on the globe contains the selective environment to produce these violent storms. Besides areas in North America, South America, particularly Argentina and Brazil, receive a great deal of hail and tornadoes annually.
