“…The concept of creating charged aerosol particles in order to model a lightning discharge in laboratory was proposed in the 1960s (Barreto, 1969). The setup used in this work is based on a condensing steam generator (Temnikov et al, 2009;Vasilyak et al, 2003). Its outdoor version was described in Kostinskiy et al, 2016).…”

Effects of lightning‐induced generation of high‐frequency and microwave radiation are of great interest for studying fundamental physics of lightning and its applications for monitoring of the thunderstorm activity and protection of equipment against electromagnetic interference. Ultrawideband electromagnetic pulses (UWB EMPs) of spark discharges about 1 m long were detected in a frequency band of up to 10 GHz in laboratory experiments using a cloud of water droplets charged up to the electric potential exceeding 1 MV. Electromagnetic pulses with characteristic front buildup durations from 50 to 100 ps were produced by streamer flashes, at the stage of leader propagation and the main stage of the discharge (i.e., the return stroke). Electric and magnetic fields of pulses were measured, and the radiation polarization was determined. The UWB EMP waveforms and the spectra obtained experimentally are consistent with colliding streamer models.
