They can occur anywhere in the world given the right conditions, especially after the landfall of hurricanes.
A violently rotating column of air associated with a thunderstorm that is in contact with the ground. Tornadoes are categorized as weak, strong or violent with winds of up to, or more than 300 mph.
A violently rotating narrow column of air in contact with the ground and extending from a thunderstorm base. The tornado is most often found in the southwest quadrant of the storm, near the trailing edge of the cumulonimbus cloud. Tornadoes and funnel clouds are usually pendant from (1) wall clouds, or (2) directly from the thunderstorm base, within a few miles to the southwest of the precipitation shaft. The spinning motion of a tornado is most often left to right on the front side and right to left on the backside (counterclockwise). Tornadoes have been called twisters and cyclones, but these words are all synonyms for the most violent storm on earth, with estimated wind speeds up to 300 mph.

A violently rotating column of air in contact with the ground and extending from the base of a thunderstorm. A condensation funnel does not need to reach to the ground for a tornado to be present; a debris cloud beneath a thunderstorm is all that is needed to confirm the presence of a tornado, even in the total absence of a condensation funnel.

A tornado appears as a violent funnel-shaped wind vortex in the lower atmosphere with upward spiralling winds of high speeds - spawned by severe thunderstorms. The tornado usually appears from a bulge in the base of a cumulonimbus cloud. It has a typical width of tens to hundreds of meters and a lifespan of minutes to hours. In area, it is one of the least extensive of all storms, but in violence, it is the world's most severe. More tornadoes occur in the United States than in any other country. In Canada, when they do occur, it is mainly in the Prairies and southern Ontario.
A very intense circular windstorm born out of a thunderstorm. Wind speed may exceed 300 km/hr.

They can occur anywhere in the world given the right conditions, but are most frequent in the United States in an area bounded by the Rockies on the west and the Appalachians in the east.
A destructive vortex formed by extremely rapid rotation of air in and below the base of a Cb. The rate of spin reduces air pressure and causes condensation to form a funnel-shaped cloud extending down to the ground. Rotational speed may reach 300 knots, enough to destroy buildings along its track which may be less than 100 yards wide but can extend to a mile. Wide tornadoes sometimes contain several smaller 'suction vortices' rotating around the center. In the tiny town of Codell, Kansas, tornadoes hit on three consecutive years--1916, 1917, 1918--and each time on the SAME date: May 20! Though on a much smaller scale (F0 and maybe F1), Los Angeles and surrounding area has experienced more tornadoes than the Kansas City area over the past 20 years! Tornadoes once fought for this country too!....... During the War of 1812, more British troops were killed or injured by a monstrous tornado that roared through Washington D.C., than from all the firepower the American troops could muster trying to defend the city.
vortex of rapidly moving air associated with some severe thunderstorms. Winds within the tornado funnel may exceed 500 kilometers per hour.
A violent storm of whirling winds of high speed, over a narrow path often accompanied by a funnel shaped cloud.
A local atmospheric storm, generally of short duration, formed by winds rotating at very high speeds, usually in a counter-clockwise direction. The vortex, up to several hundred yards wide, is visible to the observer as a whirlpool-like column of winds rotating about a hollow cavity or funnel. Winds may reach 300 miles per hour or higher (FEMA definition). See Natural Disaster.
