Tornados
by Joshua Kim
Firefighters from Washington, Illinois, stand near flattened and
damaged homes after a tornado swept through the town on November 17.
This damage was caused by the deadly tornado. It is most common in a
place called Tornado Alley, which includes Texas, Oklahoma, Kansas, and
Nebraska. This is how a tornado occurs:
1. One way the rotation appears to happen is when winds at two different altitudes blow at two different speeds creating wind shear. For example, a wind at 1000 feet above the surface might blow at 5mph and a wind at 5000 feet might blow at 25mph. This causes a horizontal rotating column of air.
2. 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). A funnel cloud is created.
3. The rain and hail in the thunderstorm cause the
funnel to touch down creating a tornado. The tornado then is
pushed by the wind and causes destruction to anything in it's path.
Many devastating events happened when tornados strike. For example, In Michigan, two people were killed and 500,000 homes and businesses lost power. In Indiana, 12 counties reported either tornadoes or storm damage and tens of thousands of homes went dark. I bet the people in states that are in Tornado Alley were scared when these events happen. But luckily, many homes in Tornado Alley have storm shelters underground. I would be scared of the dark and the sight of the tornado. I would tell my family about the tornado. What would you do?
