1. What is a Tornado? How do they occur?

Tornadoes are mostly harmless cyclone of air that connects the earth’s surface and a storm cloud. These vertical funnels of rapid spinning air can reach a speed of about 250 miles per hour. Most tornadoes have a lifespan of only a few minutes. They are born during thunderstorms and are often accompanied by hail. They tear up everything that comes in their path. The sounds coming from a tornado can be roars, grumbles, and whirs. Tornadoes are also called twisters.

A large thunderstorm is the parent of a tornado. When warm and humid air rises inside thunderclouds and collides with cool air falls with hails or rains cyclones are formed. Under these conditions, spinning air currents develop inside the cloud. The spinning currents are initially horizontal but can also turn vertical. This connects the cloud to the earth’s surface and starts a tornado. (See How are Typhoons formed?)

Supercells are large thunderstorms that have winds already in rotation. They produce the deathliest tornadoes around the world. Tornadoes most commonly occur in the summer season. There’s a higher probability of a tornado occurring in the afternoon than day or night as in the afternoon the sun had heated the earth’s surface and atmosphere. It is ideal to produce thunderstorms.
