Hint:Let us first get some idea about tornadoes. A tornado is a violently spinning column of air that comes into contact with the Earth's surface as well as a cumulonimbus cloud or, in extreme instances, the cumulus clouds centre.
Complete answer:
Tornadoes can only develop when a thunderstorm has a specific wind pattern. As the air rising in thunderstorms is disturbed by winds flowing in various directions, it will begin to spin. It rises and is driven to one side by the storm. It rises a little higher before being jolted again by wind blowing in the opposite direction. The rising air begins to spin due to winds travelling at various speeds and directions at various altitudes.
There must also be swirling air near the ground for a tornado to develop. This occurs as the storm's air falls to the ground and spreads out in gusts over the country. Warmer air rises as the wind blows. When they blow over the ground, gusts of cooler air sink. The air above the ground begins to rotate if there are enough rising and falling gusts.
As it is pulled inward toward its axis of rotation, the spinning air above the ground speeds up.This is similar to how figure skaters spin faster when their arms are pulled in rather than outstretched. This is known as angular momentum conservation. The growing, rotating air will tilt the rotating air vertically, causing it to travel horizontally across the ground. As a result, a tornado will develop.
Note:Supercell thunderstorms produce the majority of tornadoes, but not all supercell thunderstorms produce tornadoes. For a tornado to develop, the spinning air near the ground must rotate quickly enough. If the swirling air above the ground is extremely cold, it can spread away from the storm and slow down like a figure skater with extended arms, preventing a tornado from forming.
