A tornado is a violent spinning column of air appearing like a cloud in the shape of an ice-cream cup or cone. Tornadoes are one of the most deadly and fascinating forces of nature. They can also be described as a towering black funnel extending downward from the base of a large cloud. Tornadoes usually as part of a severe thunderstorm and are also called twisters. Unlike cyclones which occur over tropical ovens, i.e. hot and humid tropical areas. Tornadoes are usually formed over land. They are formed when there is warm, moist air near the ground and cold, dry air above it.
The warm and moist air on being heated by the sun, rises up. On rising, it cools and forms large clouds. To take the place of rising air, more and more surrounding air gets sucked into the bottom of the tornado. It also sucks everything like trees, cars, houses, debris, etc., that comes near its base as it moves over an area. A tornado is smaller than a cyclone but it has high speed winds measuring upto 500 km/h. Hence, it can also cause very heavy destruction.
