Of course, we are all quite accustomed to thunderstorms. These are usually local storms. But there are certain kinds of storms that may cover thousands of square miles. One such type is called a “cyclonic storm” or “cyclone”. In a cyclone, the winds blow towards the center of an area of very low pressure.
A curious thing about them is that the winds blow in spiral fashion. In the Northern Hemisphere such storms turn anti-clockwise, in the Southern Hemisphere they turn clockwise!
A tornado is simply a special kind of cyclone. A tornado arises when the conditions that cause ordinary thunderstorms are unusually violent. There is an updraft of air. There are winds blowing in opposite directions around this rising air. This starts a whirling effect that is narrow and very violent. When this happens, centrifugal force throws the air away from being the center. And this leaves a core of low pressure at the center.
This low-pressure core acts as a powerful vacuum on everything passes. This is one of the destructive about a tornado. It can actually suck the walls of a house outwards in such a way that the house will collapse. The other destructive thing about a tornado is the high winds that may blow around the edges of a whirl. These winds can reach 300 miles per hour and nothing is safe against them
What Are The 3 Types Of Tornadoes?
1. Rope Tornado. The slenderest and most common form of twister is the rope tornado.
2. Cone Tornado.
3. Wedge Tornado.
