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

Pulse train of lightning discharge is an intracloud event that remains poorly understood especially in Malaysia. Therefore, this paper presents the frequency analysis on pulse train observed in Malacca, Malaysia. This study employed 100 pulse train samples preceding negative subsequent return stroke...
