Tornadoes are one of the most dangerous kind of storms. There winds are so strong they can ripe up a house in two seconds. Tornadoes are vertical of rapidly spinning air. Their winds may come to 250 miles and hour and can clear-cut a pathway of a mile wide and 50 miles long. Twister are born from thunderstorms and they are accompanied by hail most of the time. Giant, persistent thunderstorms called super cells spawn the most destructive tornadoes.0.jpg

These violent tornadoes happen all over the world, but the united states is the hot spots for tornadoes with about a thousand tornadoes a year. "Tornado Alley" a region that includes eastern south Dakota, Nebraska, Kansas, Oklahoma, Northern Texas, and eastern Colorado is the home to the most powerful tornadoes in the united states. U.S. tornadoes cause 80 deaths and more than 1,500 injuries per year. Tornadoes are classified as weak, strong, or violent storms. Violent tornadoes comprise only about two percent of all tornadoes, but they cause 70 percent of all tornado deaths and may last an hour or more. People, cars, and even buildings may be hurled aloft by tornado-force winds-or simply blown away.


Tornadoes form when changes in wind speed changes and the direction changes to create a horizontal spinning affect with a within a storm cell. This effect is then tipped vertical by rising air moving up through the thunderclouds. The meteorological factors that drive tornadoes make them more likely at sometimes than at others. They occur more often in late afternoon, when thunderstorms are common, and are more prevalent in summer and spring. However, tornadoes can and do form at any time of the day and year.



Tornadoes' distinctive funnel clouds are actually transparent. They become visible when water droplets pulled from a storm's moist air condense or when dust and debris are taken up. Funnels typically grow 660 feet wide. Tornadoes move up to 10 to 20 miles per hour, although they've been clocked in bursts up to 70 miles per hour. Most don't get very far though. They rarely travel mo re than about six miles in their short lifetimes.


Tornado forecasters can't provide the same kind of warning that hurricane watchers can, but they can do enough to save lives. Today the average time for a tornado alert is 13 minutes. Tornadoes can always be identified by warning signs that include a dark, greenish sky, large hail, and a powerful train-like roar. Mostly people warn everybody by the radio or stopping the program people are watching to warn them about a tornado heading in a area maybe near most people. They tell what to do for safety like they say you should get in your basement. That's the safest place to go during a tornado. If you hear the news say there's a tornado watch that means they haven't seen one yet, but if you hear a tornado warning its best to get in a safe building or a basement.
