Lightning Discharges Producing Very Strong Radiation in Both VLF-LF and HF-VHF Ranges

摘要：

We introduce the mechanism of the so-called compact intracloud lightning discharges (CID).Based on experimental evidence of multiple reflections and modeling,we infer that CID is essentially a bouncing-wave phenomenon.Some tens of reflections may occur at both radiating channel ends.The reflections have little influence on the overall CID electric field signature (narrow bipolar pulse (NBP) waveform),but are responsible for its fine structure,noisiness of dE/dr waveforms, and accompanying HF-VHF radiation bursts.
