WHAT CAUSES A TORNADO AND THE EFFECT THEY HAVE
Before we begin, you have to know what a tornado is. A tornado is an extremely destructive funnel-shaped rotating column of air that passes in a narrow path over land according to the Encarta World English Dictionary.
A supercell thunderstorm thousands of feet in the air is the place a tornado forms. Tornadoes only form under certain weather conditions. There are three types of airs for a tornado to form, warm humid air close to the ground, cold air in the upper atmosphere, and hot dry air on top that form a cap.(na, 2010) Hurricanes can form tornadoes adding to their destructive power. Hurricane Buelah in 1967 spawned 141 tornadoes. There are also waterspouts, which are tornadoes that form over the water and when they reach the land, they call them tornadoes. Tornadoes can form all over the world, but most of them are concentrated in the U.S. Great Plains area. This area is better known as Tornado Alley.
The destruction of these tornadoes is rated on the Fujita Scale, developed by Dr. T. Theodore Fujita. This scale goes from F0 to F12; this scale was used from 1971 to 2007. Since February 2007 to the present, the Enhanced Fujita Scale is used, rating tornadoes from EF0-EF5. EF0 is winds from 65-85 miles per hour (mph) with light damage, broken trees, gutters, and roof surfaces. EF1 is winds from 86-110 mph with moderate damage, mobile homes turn over, loss of exterior doors, window, and other glass
