The most powerful twisters have wind speeds of more than 300 miles (483 kilometers) per hour, which can rip buildings off their foundations. Thunderstorms occur when denser, drier cold air is pushed over warmer, humid air, conditions scientists call atmospheric instability. Tornadoes are caused by the interaction of weather systems, which create large thunderstorms (the most powerful and long-lived type is called a supercell). Between April and June 2011 tornadoes killed more than 580 people and caused over $21 billion dollars in economic damages. Unauthorized use is prohibited. In other words, in early spring, expect tornadoes in the more Southern Gulf states. A supercell tornado is usually larger and more intense than a non-supercell tornado.

Most Southern Hemisphere tornadoes occur in Australia. When winds vary in speed or direction at different altitudes a condition known as wind shear - the updraft will start to spin. USA of 105 g/L. The winds created by the growth and motion of these storms may create vortices (funnel clouds) that can descend to reach the ground, and move along the ground as tornadoes. This causes it to spin faster and reach toward A tornado, or twister, is a violently rotating column of air that extends between the Earth's surface and a cloud, usually a cumulonimbus cloud. The average width of a tornado is about 300 feet, but some can be as wide as 2.5 miles. On average, about 33 tornadoes are reported annually there.

How is it that a violent whirlwind can form in a cloud and then reach to the ground and make splinters and chaos of everything in its path? This is the reason why tornadoes usually occur during the thunderstorm in a cumulonimbus cloud when the wind direction and speed changes at high altitude thereby producing horizontal air swirl. Although the spinning currents start out horizontal, they can turn vertical and drop down from the cloud--becoming a tornado. (d) These tornado are found to occuring in many shapes and size with formation of condensation funnel. April 2011 set the U.S. record for the most tornadoes in any month. 420 g/L Still, the most severe ones have the potential to uproot homes, launch cars into the air, and transform broken glass and other debris into deadly projectiles.
