Process of Tornado Development:

• Black clouds and thunder storms
• Warm air rises into a spiraling motion
• Moisture is swept upward
• After cooling it forms a twisting, funnel-shaped cloud
• The cloud is called a vortex or an elephant's trunk
• Cold air pushes from the outside making a loud roar.
• The updraft lowers the pressure inside the funnel's center
• This causes it to pick up everything in tornaodes path
• This will make it spin until the warm air has been pushed to the top

Tornadoes come in different shapes and sizes.

Shapes:

• long and narrow ropes
• hour-glasses
• tall columns
• funnel-shaped (wide at the top and narrow at the bottom)
• outbreak (cluster of several separate tornadoes hit at the same time)
• multi-vortex (has a large and several small tornadoes instead the main funnel)
• Whirlwinds-waterspout (happen over water)

Size:

• 800-2000 feet tall
• less than 1 mile wide at the base
