Investigation of preliminary breakdown pulses in lightning waveforms

The cloud-to-ground lightning contains one or more sporadic discharges. These cloud discharges usually include a pre-starting process which is called the preliminary breakdown (PB) before a leader initiation. These breakdown processes are not well understood because of the stochastic characteristics...
