How does lightning downward leader occur

WebAt the initiation point of the connecting leader the well-known pulse-shaped lightning current occurs with an amplitude of several 1,000 Amperes up to some 100,000 Amperes. The rise time of the current is in the microsecond range. The negative charge deposited along the leader channel is discharged to the ground. WebThis electrical potential can become millions of volts in magnitude. Eventually, the electrical resistance in the air breaks down and lightning, the electrical discharge between the regions of the cloud or between the cloud and the ground, is formed. A single lightning “flash” is formed by a series of lightning “strokes”.
