Sometimes the spinning column of air lifts off the ground, then touches down again some distance along its path. A ten-state area of the Midwest has been named "Tornado Alley" in recognition of its attractiveness to tornadoes. Wind estimates vary with height and exposure. The storm's maximum recorded windspeed was at least 302 miles per hour (486 kilometers per hour), and its largest width was 2.6 miles (4.2 km). -In the west-central United States, warm, moist air comes in contact with warm, dry, desert air, and the moist air is pushed upward. Only one ancient account mentions the existence of Xerxes Canal, long thought to be a tall tale. The widesttornado ever recorded was a multiple-vortex tornado. This time there was. The collision of warm, moist air and cold, dry air causes tornadoes. The average forward speed of a tornado is about 10 to 20 miles per hour. The worst of all natural catastrophes are believed to be weather-related events, including tornadoes, hurricanes, and floods. When these two air masses meet, they create an area of low pressure, as the warm air rises through the colder air, which can cause the air to start spinning. Most tornadoes, however, are comparatively weak events that occur in sparsely populated areas and cause minor damage. 'Tornadic waterspouts,'often known as 'tornadoes over water,'can be created by supercell thunderstorms in a manner that is the same as land-based tornadoes- except they just happen over water. Where do these violent and unpredictable storms come from? When the jet stream is strong and moves in the right direction, it can push the warm, moist air and cold, dry air together, creating the conditions needed for a tornado to form.

Supercells can also produce various severe weather phenomena, including large hail, strong winds, and of course tornadoes. We have circumstantial evidence, yes, but the key caveat is that favourable conditions do not guarantee that a storm occurs, Tippett said. Tornadoes can last for a few minutes or several hours, and their size and intensity can vary greatly. A tornado is a "rapidly rotating column" of air which is in the contact with both the surface of "earth and cumulonibus cloud". Which of the following statements about tornadoes is false? Tornadoes are most common on continents in the midlatitudes (between 20 and 60 degrees north and south), where they are frequently associated with thunderstorms that develop in regions where cold polar air meets warm tropical air. Large temperature differences are associated with early winter cold fronts that move rapidly across the country from the north and west, at times spawning widespread outbreaks of small tornadoes. There are several different types of tornadoes, each with its own characteristics and level of intensity. In Kentucky, the worst-hit state, one tornado alone followed an extraordinarily long and destructive path of more than 200 miles.

Tornadoes can occur anywhere in the world. But no one ever knows when, where, how intense, and how many tornadoes a thunderstorm will create. Scientists probe the mysteries of violent twisters. The most common type of tornado comes from a supercell thunderstorm. Tornadoes can be among the most violent phenomena of all atmospheric storms we experience. A tornado, or twister, is a violently rotating column of air that extends between the Earth's surface and a cloud, usually a cumulonimbus cloud. While scientists know the specific meteorological conditions needed for tornadoes to form, they are still researching exactly what triggers a tornado. Insurance records show that tornadoes have caused significant losses in Europe, India, Japan, South Africa, and Australia. Biden has separately announced that he will ask the Environmental Protection Agency to examine what role climate change might have played in the storms. Tornadoes form in unusually violent thunderstorms when there is sufficient (1) instability and (2) wind shear present in the lower atmosphere. When wind shear is present, it can cause the air to spin, eventually turning into a tornado. GOES-16 imagery of a tornado-producing storm in southwest Iowa on June 28, 2017.
