Also known as twisters, tornadoes are born in thunderstorms and are often accompanied by hail. Tornadoes form when warm, humid air collides with cold, dry air. tornado, a small-diameter column of violently rotating air developed within a convective cloud and in contact with the ground. Averagely, 80 deaths as a result of devastating tornadoes are recorded each year. Tornadoes can reach wind speeds of more than 300 miles per hour. This can then tighten and intensify its rotation and bring it down to the ground to produce a tornado. The rating scale for tornadoes is based entirely on the damage they cause. Why do they destroy some buildings, but leave others nearby untouched? Because tornado formation is closely tied to the speed and directional shear of the wind with height, tornadoes in the Southern Hemisphere almost exclusively rotate clockwise, opposite to the rotation of their Northern Hemisphere counterparts.

In other words, a tornado is a funnel-shaped violent windstorm that whirls upwards rapidly with a tip touching the ground. Scientists have been wary of attributing the frequency and intensity of convective storms that can produce tornadoes to climate change, in part because historical and observational data around tornadoes is relatively limited. Biden has separately announced that he will ask the Environmental Protection Agency to examine what role climate change might have played in the storms. Jennifer Francis, a senior scientist at Woodwell Climate Research Center, said climate change was making some of the ingredients needed to create an outbreak like this more likely.
