Abstract
This paper reports a recent observation of Narrow Bipolar Pulses (NBPs) occurrence between return strokes (RSs) of negative cloud-to-ground (CG) flashes in tropical thunderstorms. A wideband electric field antenna measurement system has been used in this work and 173 isolated and non-isolated NBPs managed to be recorded. We found that 22 single NBPs and a pair of positive NBP embedded between RSs and some of them are located within the horizontal distance range from 20 to 45 km from the observation station.
