Temporal analysis on pulse train of lightning discharge observed in Malacca, Malaysia

A few significant studies discovered that a pulse train tends to initiate subsequent return stroke in the same way that a preliminary breakdown pulse activates the first return stroke. This paper presents pulse train characteristics in the lightning waveform obtained in Malacca, Malaysia. This study...
