Tornados are a very devastating weather phenomenon. Tornados develop in super cell thunderstorms and sometimes in hurricanes. Waterspouts are tornados that occur over water. Tornados are formed within a thundercloud when the direction of wind varies with height. This causes a rotation to form in the cloud. Eventualy the rotation may make it's way down to the surface as a tornado. A tornado is rated from 0-5 and as weak, strong, or violent. The scale that determines this is called the Fujita Tornado Intensity Scale (see below).
|Scale||Category||Force (mph)||Path Length (miles)||Path Width (yd/mi)||Damage|
This shows how destructive a tornado can be (left). This was a F5 tornado that ripped through the small town of Jarrell, TX killing 27 and injuring many more. This was a waterspout just off the coast of Miami, FL (right) nobody was hurt by this waterspout becuase it never made it to land.
