Abstract

As known the lightning incidence of a vertical structure is related to the physical processes involved in the final stage of the progression of the downward lightning leader to the structure and upward streamers, in case downward flashes are taken into account. Within this context, the paper presents and discusses a numerical implementation based on the Finite Element Method (FEM) of the Leader Progression Model (LPM): LPM-FEM. The obtained results are compared with those of the original implementation of the LPM based on the charge simulation method and the relevant differences analyzed and discussed.
