TORNADO

WHAT IS A TORNADO

• A tornado is a violently rotating column of air that touches the Earths ground and the cumulus cloud

HOW TORNADOS FORM

• They rotate because of the wind shear
• Rotation happens when winds of 2 different altitudes blow at different speeds that creates a wind shear
• If the column gets caught in a supercell updraft the updraft tightens and the spin and then it speeds up then a funnel cloud is crated
• The rain and hail in the thunderstorm causes the funnel to touch the ground making a tornado
