Whats is Tornadoes? Tornadoes are small, very powerful full whirlwinds. They form suddenly into a rapidly twisting funnel of air and cloud that stretches from the bottom of a thundercloud to the ground.
How to Tornadoes Form?
A Tornado starts deep inside a thundercloud when a column of rapidly rising warm air is set spinning by the strong wind blowing through the top of the cloud. Like a hurricane, a Tornado is powered by rising humid air. However, a Tornado is narrower, faster, and more violent than a hurricane and it destroys everything in its path. Tornadoes often occur in small groups and unlike hurricanes, are often found far inland. Although a tornado travels across the land at speeds of only 30 to 65 kilometers an hour, the wind speed inside the tornado can reach 800 kilometers an hour. A tornado may measure anything from just a few meters to more than 100 meters across. It can travel for more than 200 kilometers before it uses up all its energy. Occasionally a tornado lasts for serval hours, but most last for only a few minutes.
Although a tornado affects only a small area, it can cause more damage than any other kind of weather.
A large tornado destroys everything in its path. It sucks u sand, car, buildings, and even people and animals, like a gigantic vacuum cleaner.
Where do tornadoes occur?
Although tornadoes can develop in most parts of the world, they are most common in the united states, where they are often called ‘twisters,. On average, about 1200 tornadoes occur there every year. Tornadoes also occur regularly in parts of Canada, Argentina, Chine, Australia, South-west Asia, and Europe. They can occur anywhere there are thunderstorms.

If a tornado forms over a lake or the sea it is called a waterspout. The funnel of a waterspout looks white because it contains tiny droplets of water that have cooled and condensed from the whirling funnel of air.
Waterspouts usually last only a few minutes. Although they are less powerful than land tornadoes, some waterspouts have wrecked boats, jetties, and houses along the coast.
