Tornado formation, illustration. From left to right, the formation of a tornado is shown in four stages: initial updraft, impact with cold front to create spiralling air, further uplift, and then impact with the ground. A tornado is a violent rotating column of air that can form during the growth of a cumulonimbus (thunderstorm cloud). Large tornadoes form from severe thunderstorms called supercells, and can be devastating in their impact with extremely high wind speeds. | |
