Ingredients for Severe Thunderstorms

What atmospheric conditions are necessary for the formation of severe storms?

  • a triggering mechanism to initiate the convection, e.g.,
    • dryline
    • cold front
    • terrain
  • Large convective instability (warm air at low levels, cold air aloft)
  • lots of low-level moisture
  • lots of vertical shear (suggests what needs to be overhead?)

So, what will the sounding look like???? --->>
