  • Tornado (U*X*L Encyclopedia of Weather and Natural Disasters)
    A tornado is a rapidly spinning column of air that extends from a thunderstorm cloud to the ground. The tornado rotates around a vertical axis of extremely low pressure called a vortex. Tornadoes are sometimes called "twisters" or "cyclones," although the term cyclone is also used to described hurricanes in the Indian Ocean.
