What are the stages of a tornado?

A tornado’s development can be described by a sequence of distinct phases. Sunshine heats the ground which in turn heats the air near ground level. Localised pockets of air become warmer than their surroundings and begin to rise. Cumulus clouds are formed, which grow until they become a storm cloud (cumulonimbus).
