Discussion: How do tornadoes happen in the real world? There are two winds, moving in opposite directions. When they meet they don’t want to bump together so they spin and spin and spin horizontally.Then hot humid air rises to make thunderclouds. So the rising air spins the tornado vertically in the cloud. When the cool air moves downwards, itpulls the spinning air to the ground and makes a tornado. Tornadoes are made from super cells that are very strong. They pull on dust and debris. Tornadoes wreck buildings and throw trucks and cars in the air.
