Oh No!!!!!! TORNADOES!!!!!!
What exactly is a tornado?
What are the causes of tornadoes?
Tornadoes form in unusually violent thunderstorms.When there is sufficient (1) instability and (2) wind shear present in the lower atmosphere.Instability refers to unusally warm and humid weather in the lower atmosphere. Wind shear in this situaiton of tornadoes refers to to the wind direction changing. The particular kind of wind shear and instability usually exists only ahead of a cold and low pressure system. The intense spinning of a tornado is partly the result of the updrafts in the thunderstorm inerating with the wind shear.
