A tornado is formed by a stream of cold air going across the ground. At the same time there might be a stream of warm air traveling in the opposite direction. Once that air starts to spin an updraft will make it turn on its tip. It is like spinning A football on its side really fast. The result should be that the football turns on its tip. Eventually The tornado will touch the ground because of gravity. And then that is when the whole wizard of Oz tornado picking the house off of the ground and Dorthy and her dog get picked up into the tornado and go to Oz. There was a massive tornado in barnivelled wisconsin during the 1900's and wiped out the whole entire city. There was also a big tornado in flint michigan. Another recent tornado is in Mississippi. It killed 5 Mississippians. That tornado was a very big tornado. Humans have prepared for tornados by going into basements when there is a tornado alert or by making tornado shelters. Once the coulds turn grey, and the wind speed picks up you should probably head inside.
