Abstract: Unique lightning signatures have been observed from sub-tropical, mountainous country, Nepal. These signatures were observed by measuring the electric field using a simple circuit and antenna system. The unique unusual signatures analysed are assumed to be positive ground flashes. These lightning signatures were each characterised by a relatively slow, negative electric field events preceded by a pronounced opposite-polarity pulse. The average durations of the main waveform was 523.84 μs and the average duration of preceding opposite-polarity pulses was 37.99 μs.

Keywords: unique waveforms; unusual lightning; Himalaya's thunderstorm; opposite polarity-pulses; Nepal.
