Tornadoes

Tornado Formation
In tornado alley, twisters are normally caused when warm, humid winds from the Gulf of Mexico move north and collide with cool, dry air from the west


















As the warm air and colder winds collide, they begin an invisible horizontal rotation.
Energy from the sun warms the ground, which in turn warms the air near it. This warm air then rises even further.
This warm air pushes itself upwards through the colder air and starts to form a vortex.
This then forms into the fully-fledged funnel of a tornado.
