Shawnee,Oklahoma Tornado.

The tornado that occurred at Shawnee, Oklahoma has killed two people and caused a a great majority of property damage.Also at this point there is another storm expected an up to 500,000 square miles.

Tornado is a destructive rotating column of air that has very high wind speeds and that maybe visible as a funnel-shaped cloud.

How do tornados form

The column of air begins to rotate is not completely understood by scientists, but one way the rotation appears to happen is when winds at two different altitudes blow at two different speeds creating wind shear.

If this column gets caught in a supercell updraft, the updraft tightens the spin and it speeds up (much like a skater's spins faster when arms are pulled close to the body).

The rain and hail in the thunderstorm cause the funnel to touch down creating a tornado.

Speed of the Two Tornadoes

Shawnee- Mile-wide tornado with winds up to 200 mph.

Moore- 300 mph, the highest wind speed ever recorded near the earth's surface.

The Type of Scale (Fujita)

The Fujita is to measure the tornadoes intensity, measures the strength of a tornado based on its damage it produces. The Scale's rating is from F0 to F5.
