The phenomenon of regular pulse bursts in lightning research is characterized by continuous pulses occurring at regular intervals, resulting in intermittent rapid changes in the electric field at ground level. The individual pulses last for microseconds, while the entire sequence can last for milliseconds. The mechanism behind their occurrence has long puzzled scientists.
