Abstract
In this study, electromagnetic field radiation bursts known as chaotic pulse trains (CPTs) and regular pulse trains (RPTs) generated by lightning flashes were analyzed. Through a numerical analysis it was found that a typical CPT could be generated by superimposing several RPTs onto each other. It is suggested that the chaotic pulse trains are created by a superposition of several regular pulse trains. Since regular pulse trains are probably created by dart or dart-stepped leaders or K-changes inside the cloud, chaotic pulse trains are caused by the superposition of electric fields caused by more than one of these leaders or K-changes propagating simultaneously. The hypothesis is supported by the fact that one can find regular pulse trains either in the beginning, middle or later stages of chaotic pulse trains.

In pulse addition to providing thehypothesized, statistical data for the of chaotic pulse trains (CPTs) and regular trains (RPTs), we based onfeatures the features of pulse trains (CPTs) and regular pulse trains (RPTs), we hypothesized, based on the features of measured measured RPTs and CPTs, that the CPTs are possibly formed by a superposition of RPTs
Summary
Regular pulse trains (RPTs) consist of a train of pulses each with a signature similar to electric field pulses generated by dart leaders. According to Krider et al [1], RPTs are generated by a dart-stepped leader or K-changes type discharges propagating inside the cloud. Each pulse train had a typical duration of 100–400 μs with a mean time interval between individual pulses of about 5–6 μs. According to Rakov et al [2], the amplitude of individual pulses in RPTs is about two order of magnitude smaller than the return stroke (RS) pulses. The observation made by Rakov et al [2] shows that the RPTs occur both in cloud flashes and during cloud activity between return strokes
