In this review we describe a transient type of gas discharge which is commonly called a
streamer discharge, as well as a few related phenomena in pulsed discharges. Streamers …

Despite being one of the most familiar and widely recognized natural phenomena, lightning
remains relatively poorly understood. Even the most basic questions of how lightning is …

A long-standing but fundamental question in lightning studies concerns how lightning is
initiated inside storms, given the absence of physical conductors. The issue has revolved …

It is by now well understood that large sprite discharges at the low air densities of the
mesosphere are physically similar to small streamer discharges in air at standard …

Extremely low frequency (ELF) and very low frequency (VLF) observations have formed the
cornerstone of measurement and interpretation of effects of lightning discharges on the …

This paper presents a literature survey on the recent developments related to experimental
and modeling studies of transient luminous events (TLEs) in the middle atmosphere termed …

There are many open questions about prebiotic chemistry in both planetary and
exoplanetary environments. The increasing number of known exoplanets and other ultra …

While narrow bipolar events (NBEs) could be related with lightning initiation, their intrinsic
physics remains in question. Here we report on optical measurements by the Atmosphere …

Streamer discharges are the primary mode of electric breakdown of air in lightning and high
voltage technology. Streamer channels branch many times, which determines the …

We study negative streamers in ambient air using a 2D axisymmetric fluid model. Depending
on the background electric field, we observe accelerating, steady and fading negative …
