Full Answer

By far, the United States produces the most tornadoes each year; about 1,200 tornadoes occur in the U.S. alone. When cold, dry air from the Arctic meets warm, moist air from the Gulf, conditions become favorable for the formation of tornadoes. The most dangerous tornadoes form from thunderstorms called supercells. Tornado Alley, which sees the most tornadoes in the world, stretches from central Texas northward to Iowa. Historically, Oklahoma City has been the city hit with the most tornadoes. Many tornadoes that occur in the United States do not cause damage because they are weak, ranging from a rating of EF-0 to EF-1.

  • Q:

    How are tornadoes and hurricanes alike?

    A:

    The only significant similarity between tornadoes and hurricanes is that they both produce high-speed winds. Tornadoes form as the result of lingering strong vertical wind velocity and vertical temperature changes. Hurricanes form as the result of extended periods of weak vertical wind velocity and relatively low changes in atmospheric temperature.
