High-speed footage of a classic lightning strike, showing stepped leaders of charge heading downwards, until one makes contact with the ground, forming a channel through which the main discharge can travel. The return strokes show m-component fluctuations and continuing currents. Filmed at 7200 frames per second in South Dakota, USA, in spring. | |
