Planet Diary:  Tornado
http://www.phschool.com/science/planetdiary/background/torn.html
Tornadoes are rotating columns of air that descend to the ground from thunderstorm clouds. The wind speeds of tornadoes range from 75 to 300 miles per hour. Tornadoes can toss 13-ton vehicles thousands of feet and send pieces of straw through wood. In the United States, they are most prevalent during the spring and summer in the infamous "Tornado Alley" between Nebraska and Texas. Tornadoes almost always make the news because they are so destructive.
