How Does Tornado Form?

In this Essay, I am going to write how does a tornado form? There is still much we don't know about tornadoes, but this gives you a good idea of how they might form under these conditions. Warm moist air shoots upward meeting colder, dryer air.  Warm moist air is lighter than the cold dry air making for a strong updraft within the thunderstorm. As the warm moist air rises, it may meet varying wind directions at different altitudes.

If these varying winds are staggered in just the right manner with sufficient speed, they will act on the upward rising air, spinning it like a top.   This would be similar  to spinning a pencil held between your hands with your palms facing each other, moving your hands in opposite directions. The storm will begin to show visible rotation, often forming a wall cloud. Inside the storm these spinning winds can begin the formation of a tornado. On the outside of the thunderstorm rotation might be visible. Only about 30 percent of mesocyclones actually produce a tornado, but about 95 percent produce severe weather.  Most of our information about the inside of a tornado-generating thunderstorm comes from data gathered by Doppler radar.  The illustration below be an example of how a tornado would typically form in this type of thunderstorm.

In a severe thunderstorm the down drafts and updrafts actually feed each other giving the storm a life of its own.  Whereas an ordinary thunderstorm might only last 30 minutes to an hour a severe thunderstorm self generates its life so that it may last several hours or more. Severe storms produce downdrafts that can get very strong causing a microburst. These can be as damaging as an f1 tornado, toppling mobile homes, knocking down trees and damaging buildings
