Characteristics of an `average` lightning flash:-

Stepped leader takes 0.005 secs to develop.

Return stroke takes 0.0001secs (about 1/3 the speed of light).

Return stroke

200,000,000 volts potential over length.

Current 50,000 Amps.

Core temperature 25,000 C (about 5x hotter than surface of the Sun).

Length 5 miles.

There are 1200 thunderstorms per hour over the Earth`s surface. Each will have about 1,000 flashes of lightning. A thunder cell within a cumulo-nimbus cloud recharges in 30 seconds.
