cyclone

A cyclone is another word for "tornado" or other types of violent, spinning storms. It was a cyclone that uprooted Dorothy in "The Wizard of Oz," and her little dog Toto too.

In the midwestern part of the United States, a cyclone is a tornado. But ask a meteorologist and he'll tell you that technically a cyclone is a rapidly rotating storm that forms over a warm ocean, specifically in the South Pacific. Tropical cyclones are actually much bigger than tornadoes: a small cyclone could be 100 miles across, while a monster tornado would only be about a mile across.
