Modeling of the final jump phase of a positive lightning leader

Behavior of the potential and electric field intensity at the front of a lightning leader channel taking into account the influence of space charges injected by the streamers is investigated theoretically. Analytical solutions of Poisson equation are found for different laws of charge density distribution in the streamer zone. Influence of the streamer zone parameters on the formation of final jump phase of a leader is investigated.

Electromagnetic fields created by the lightning leader channel in the final jump phase

The dependences between the parameters of the Lightning discharge in the leader phase and the return stroke phase are obtained. It is shown that the peak values of the electric field created by lightning are determined by the parameters of the streamer zone of the leader at the final jump phase. It is shown that a large peak value and the steepness of the lightning return stroke current are generated in the final jump phase.
