The main difference between a tornado and a cyclone is that a tornado is a rapidly rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud, while a cyclone is a large rotating storm system that has thunderstorms around its center. Tornadoes form quickly, usually within minutes, while cyclones can take hours to develop. Tornadoes are typically smaller than cyclones, but they can produce stronger winds.
