A 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
A small, very intense cyclonic storm with exceedingly high winds, most often produced along cold fronts in conjunction with severe thunderstorms
A violent storm where various natural forces cause a strong circular wind that can reach over 300 miles per hour Like some natural disasters, they are unpredictable and unpreventable, and they cause indiscriminate damage, so they tend to not cause a diminution in value to a particular property or neighborhood but rather impact a large region
A twisting, spinning funnel of low pressure air The most unpredictable weather event, tornadoes are created during powerful thunderstorms As a column of warm air rises, air rushes in at ground level and begins to spin If the storm gathers energy, a twisting, spinning funnel develops Because of the funnel's cloud and rain composition and the dust, soil, and debris it draws up, the funnel appears blackish in color The most energetic storms result in the funnel touching the ground In these tornadoes, the roaring winds in the funnel can reach 300 mph, the strongest winds on Earth Funnels usually travel at 20 to 40 mph, moving toward the northeast When tornadoes form over lakes or oceans they suck water into the funnel cloud and are called waterspouts
is a strong, rotating column of air extending from the base of a cumulonimbus cloud to the ground These twisting, spinning funnels of low pressure air are the most unpredictable weather event, created during powerful thunderstorms
A 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
a localized and violently destructive windstorm occurring over land characterized by a funnel-shaped cloud extending toward the ground
a powerful column of winds spiraling around a center of low atmospheric pressure
A violent storm characterized by strong swirling winds and updrafts; tornadoes form when a strong cold front pushes under a warm, moist air mass over the land
A 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
a tempest distinguished by a rapid whirling and slow progressive motion, usually accompaned with severe thunder, lightning, and torrents of rain, and commonly of short duration and small breadth; a small cyclone
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 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 (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 rapidly rotating column of air which is attached to a thunderstorm and is in contact with the ground
In the TALC, a period of rapid growth in which most pragmatist buyers first adopt a product based in a new technology
A vortex of rapidly moving air associated with some severe thunderstorms Winds within the tornado funnel may exceed 600 kilometers per hour
