A review of the modeling approaches of the lightning M-component with special attention to their current and electric field characteristics

Marcos Rubinstein, Mohammad Azadifar, Farhad Rachidi-Haeri, Carlo Alberto Nucci, Qi Li

In this paper, we present the characteristics of current, electric fields and modeling approaches of lightning M-component mode of charge transfer. We consider both the classical M-components (occurring after return strokes) and M-component-type ICC (Initi ...
