Tornadoes are violent windstorms that form a vortex and reach up to 300 m/ph.
The United States has an average of 770 tornadoes every year.
How Tornadoes Form
- All tornados begin with a thunderstorm. This is when warm and unstable air rises.
- The warm air begins to rotate, causing a mesocyclone to be formed.
- The air begins to roll, creating the vortex.
