A new model of lightning subsequent stroke - Confrontation with triggered lightning observations
Abstract
A theoretical model describing the displacement of electric charge and the flow of electric current during a subsequent lightning stroke is developed, and model predictions are compared with published observational data from triggered-lightning experiments (Hubert et al., 1984). The model explains the return stroke in terms of the negative charge delivered by the dart leader to the earth, taking into account the fact that the channel is not straight and vertical. The model is found to predict the current and magnetic-field signals accurately but to give a value of the electrical-field jump at 100 m which is 3.7 times greater than that observed for subsequent strokes.
