- Batı Afrika kıyılarında esen çok kuvvetli kiklon.
- Violently rotating column of air in contact with and extending between a convective cloud and the surface of the earth It is the most destructive of all storm-scale atmospheric phenomena 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.
- Violently rotating column of air that is in contact with the ground Tornadoes usually develop from severe thunderstorms and can produce winds of 100 to 300 mph.
- Appears as a powerful, funnel-shaped wind current in the lower parts of the atmosphere with winds that twist upwards at high speeds - often spawning from severe thunderstorms The tornado usually emerges from the base of a cumulonimbus cloud It usually has a width of tens to hundreds of meters and can last only minutes to several hours Tornadoes occur in the United States more than any other country In Canada most tornadoes occur in the Prairies and in Southern Ontario.
- Violent rotating column of air, in contact with the ground, pendant from a cumulonimbus cloud A tornado does not require the visible presence of a funnel cloud.
- 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 cumulonimus cloud Tornadoes and funnel clouds are usually pendant from wall clouds or 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 backside 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.
- Tornado is a violently rotating vortex of air in contact with a parent cloud and a land surface.
- Violently rotating column of air, reaching down from a cumulonimbus cloud and touching the ground Generally observed as funnel-shaped, it is the most destructive of all storm-scale atmospheric phenomena They occur only in certain areas of the world and are most frequent in the United States in an area bounded by the Rockies on the west and the Appalachians in the east.
- Violently rotating column of air, pendant from a cumulonimbus cloud, and nearly always observable as a funnel cloud or tuba On a local scale, it is the most destructive of all atmospheric phenomena Its vortex, commonly several hundred yards in diameter, whirls usually counterclockwise with wind speeds of 100 to more than 300 miles per hour Its general direction of travel is governed by the motion of its parent cloud.
- Violent rotating column of air, usually forming a pendant from a cumulonimbus cloud with the circulation reaching the ground It nearly always starts as a funnel cloud and may be accompanied by a loud roaring noise On a local scale, it is the most destructive of all atmospheric phenomena.
