Mechanism of lightning discharge
WebThe leader stroke mechanism for the lightning discharge is explained on the basis of ion recombination in the discharge channel. It is assumed that a pilot streamer advances continuously from cloud to ground at a speed of 2 × 107 cm per sec. WebNov 13, 2024 · Cloud-to-ground lightning discharges are of utmost interest because of their hazards to life and property. The high current flowing during the lightning flash can melt conductors, ignite fires, damage equipment, trip power circuits, and produce deadly voltages for living creatures.
