摘要: [1] Mainly based on the channel base current of 0803 and 0902 flashes detected in Shandong Artificial Triggering Lightning Experiment (SHATLE) from 2005 to 2010, waveforms six return strokes an RM process (a characterized by both a stroke M-component) containing subsidiary peaks were analyzed. The percentage with peak is approximately 17%. amplitudes primary varied 8.53 16.34 kA 5.40 15.86 kA, respectively. time intervals between secondary 6.3 12.0 μs. have different waveform characteristics, indicating that mechanisms generating two lightning may be different. To learn more about causes forming assumption branches every corresponds physical process, Heidler function model was used simulate four flash 0902. simulated results indicated component could reflect characteristics some extent. Based comparison waveforms, possibilities proposed: branching, flashover along triggering wire previous unsuccessful launch, corona or reflection current. Branching main flashes,
