A) condensation B) dry climates C) wind shear D) stationary fronts Get the answers you need, now! Conditions are ripe for tornadoes when the air becomes very unstable, with winds at different altitudes blowing in different directions or at different speedsa condition called wind shear. In exceptional cases, violent events can last more than three hours. Usually, theres not a lot of instability in the winter thats needed for tornadoes because the air isnt as warm and humid, he added. Russia may have many tornadoes, but reports are not available to quantify their occurrence. It's hard to measure the winds in a tornado directly. Each level in the Enhanced Fujita Scale is derived from three-second wind gusts estimated at the point of damage to 28 indicators (such as trees, buildings, and various types of infrastructure) and the degree of damage to each indicator. A cold front For the Tornado Alley in the U.S., this air typically comes from the Gulf of Mexico or the Pacific Ocean. Most tornadoes are harmless and brief.
