what atmospheric conditions are necessary for the formation of super cells that spawn tornadoes?
-cold, dry air overlaying warm moist air creates convective instability.
-adding in wind shear will create rotation.
-the combination of cold, dry air, warm,moist air, and warm dry air will create a dry line which creates the ideal conditions for a tornado
-then, some sort of trigger is required to produce the tornado(cold front, thunderstorm, lifting mechanism, etc)
