Abstract

A statistical model describing the electrical physical processes in the last stage of propagation of lightning leader channel to the ground, taking into account the possibility of appearance the ascending sparks from ground objects has been proposed. Experimental data on the speed of the lightning leader channel, the electric field strengths necessary for development of leader channels of negative and positive polarity, specific linear conductivity of the leader and streamer channels, etc. are laid in the basis of the model. Compliance of this model with the investigated process has been validated by comparison of the results of calculation of probabilities of places of high-voltage discharge strikes to the earth and located on it objects with known experimental data. References 15, figures 2.

Key words: leader channel of lightning, electrical physical processes, statistical model, probability of lightning stroke, lightning rod.
