Thundercells and Thunderstorms
Most lightning activity in North America is the result of a separation of electrical charges due to air turbulence created when a summertime cold front from the north collides with a warm air mass sweeping up from the south. The “frontal” or “squall line” storms thus created are large-scale events whose turbulent fronts may extend several hundred miles, across several states.
