Thunderstorms have 3 main Stages. The first stage is called the cumulus stage. In this stage warm air rises and the storm begins to form. The second stage is called the mature stage. This stage is the climax of the storm, it is at its biggest and there is precipitation. Dissipating Stage is the final stage in a thunderstorm. There is precipitation and the cloud cools down.
Tornadoes are a very deadly and powerful storm. Just like thunderstorms, tornadoes have 3 stages in formation. It all starts out with warm, unstable air rising. That air then begins to rotate. Finally the air begins to roll, creating a vortex, and thus a tornado is born.
Hurricanes are the most powerful storms on the Earth. These monstrous storms have 5 stages. They begin as a bunch of thunderstorms. Things begin to escalate when warm air from the storms move. Next the clouds form a ring (eye wall). After that the ring spins and grows, the destructive nature of the storm becomes apparent. The storm will wreak havoc until it dies on land.
