Tornadoes are one of the most violent natural phenomena. Rotating it winds can reach speeds of 480 km / h (equivalent to 300 miles per hour), it is easily jump into the air car or cow.

Tornado is a massive natural phenomenon, especially in the United States, where it is fixed about 1,300 tornadoes per year. Most of them formed on broad band plains, which is popularly referred to as the Valley of the tornado. Tornadoes are fixed everywhere, on all continents except Antarctica.

Explore the nature of a tornado to the meteorologists. Today, they face the challenge to learn more about how, why and when a tornado is formed of strong thunderstorms called supercell.

"There is some as yet unknown component that allows tornadoes form of heavy thunderstorms, but we do not yet know what it" - says Joshua Wurman, founder of the Center for Studies of extreme weather events in Boulder (Colorado). If scientists can improve the system of predicting the weather, provide more precise advance warning of a tornado, it will help save lives. We remind you that the average time a tornado warning - 15 minutes.
