How many types of tornadoes are there? What are they?

There are four types of true tornadoes. There is the multiple vortex tornado, it usually has two or more funnels of clouds rotating around a common centre. A satellite tornado is a smaller, weaker tornado that orbits around a larger and stronger tornado. A water spout is a tornado formed over water, and a land spout is a tornado on land. A land spout is smaller than many other tornadoes, but is quite strong.

The other types of tornadoes are tornado-like circulations. The gustnado is a small, vertical swirl. It is created by the cold, dry outflow of air from thunderstorms. Dust devils are vertical swirling columns of air. It is formed under clear skies and usually in hot areas. They are not as strong as even the weakest tornadoes. A fire whirl is usually formed near large, intense wildfires. Although they are not usually thought of as tornadoes, they can still cause a considerable amount of damage. Steam devils are swirling updrafts that can form near hot springs and deserts. They are very rare, and there also have been some reports of cold air steam devils.
