Tornadoes are violently rotating columns of air rising up into a cloud. A thunderstorm is the first step in the creation of a tornado. A thunderstorm happens when there is moisture in the atmosphere, a lifting force causing air to begin rising, and unstable air that will continue to raise once it starts. Then, if other conditions are right, the thunderstorm may spin out one or more tornadoes.
