A tornado is a local, violent destructive windstorm occurring over land, in the usually forming in the Midwest, and characterized by a long, funnel-shaped cloud extending toward the ground and made visible by condensation (water vapor that is truing in to water) and debris, ( objects that were broken and moved with the Tornado).

How Tornadoes  Form

  • Winds at two different altitudes (high and low heights) blow at two different speeds creating a downdraft. Wind at 1000 feet above the earth might blow at 5 mph and  wind at 5000 feet above earth might blow at 25 mph. If this column of air gets caught in an updraft ( wind that blows up), the updraft tightens the spin and it speeds up. A funnel cloud is created from the high speeds of the wind. The rain and hail in the thunderstorm cause the funnel to touch down creating a tornado

Historical Examples  Of Tornadoes

Shaping The Future

Super doppler radar is just one of the many things that help protect people in a storm. People have also built storm cellars and people have used areas in houses and buildings with no windows as a shelter.If outside lie in a low area like a ditch and covering your neck with your hands is some thing that people have found that works. Warning sirens, public warning radio, and other warnings have been used.Storm chasers help get information on these major events.
