Tornado

Tornado: A violently rotating column of air extending from a thunderstorm cloud to the ground. The Enhanced Fujita Tornado Intensity Scale is used to categorize tornadoes

Funnel Cloud: A condensation funnel extending from the base of a towering cumulus or cumulonimbus, associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado). A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it.
