Investigation on the occurrence of tles associated positive cloud to ground (+CG) lightning in UMP Pekan

Lightning is one of the phenomena that occur around the area above the atmosphere. Transient Luminous Events (TLEs) is a type of lightning events which take place above the flash of lightning in a thunderstorm cloud. It is a very fast event that is hardly seen and happens in a very short period of t...
