All About Tornadoes
All About Tornadoes : Tornadoes don’t just pop into existence — they develop out of thunderstorms, where there’s already a steady, upward flow of warm, low-pressure air to get things started. It’s kind of like when a rock concert erupts into a riot. Conditions were already volatile; they merely escalated into something even more dangerous.
Thunderstorms themselves form like many other clouds: A warm, moist air mass rises and cools, causing the water vapor to condense into clouds. However, if the updraft continues, this cloud mass will continue to grow and rise 40,000 feet (12,192 m) or more up into the troposphere, the bottommost layer of the atmosphere that we live in. A typical thunderstorm cloud can accumulate an enormous amount of energy.Download your DOC : pdf
