Tornadoes have touched down in every continent except Antarctica. They can occur wherever cold, dry air hits moist, warm air high in the atmosphere. Most of the Earth's tornadoes occur in the hotbed known as Tornado Alley, but the United Kingdom reports the most tornadoes by land area, given its small size.
In Tornado Alley, thousands of twisters touch down here every year because of its geography. The alley is bordered by the Dakotas to the north, the Gulf Coast to the south, the Rocky Mountains to the west and the Appalachian Mountains to the east.
Here, warm, moist air from the Gulf of Mexico collides with the cool, dry Arctic air, fueling the massive supercell storms capable of spawning tornadoes.
Similar conditions can occur in the region where the Russian twister formed, downstream from the Himalayas and in the Gobi Desert, but, historically, reports have been rare, said Harold Brooks of the National Severe Storms Laboratory in Norman, Okla.
The Russian twister's rating on the tornado damage scale is unknown, but the twister lasted 13 minutes and caused a reported 80 million rubles ($2.9 million) in damage, according to news reports.
