Understanding the mechanism of positive leader discharge is important in lightning
protection engineering and the external insulation design in high voltage power …

Electrical discharges in long air gaps, referred to as 'leader discharges', usually propagate
with transient thermal plasma channels. The gas temperature evolution of the channels …

The elongation and branching of long positive spark discharges in the laboratory and in
lightning have been attributed to the formation of thermalized channels inside a diffuse, glow …

Leader discharge plays a key role in the breakdown of long air gap and the evolution of
natural lightning discharges. Prior to the formation of continuous leaders, streamer corona …

Transitions between the streamer and spark modes affect the stability of gas–liquid
discharges, limiting their practical applications, while the nature of such transitions is poorly …

The presence of water molecules in air introduces complexities to residual charge transports
and energy relaxations that may provoke streamer discharge instabilities under repetitive …

We investigate the effect of humidity on the propagation of streamers in air. We present a
minimal set of chemical reactions that takes into account the presence of water in a …

In this study, we present a comprehensive investigation of positive leader discharges, with
the aim of enhancing our understanding of leader decay and reactivation. Our approach …
