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 …

This paper reviews optical diagnostic methods and approaches applied to study the
fundamentals of streamer discharges, considering the peculiarities of streamers developing …

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 …

In atmospheric pressure air preheated from 300 to 1000 K, the nanosecond repetitively
pulsed (NRP) method has been used to generate corona, glow, and spark discharges …

Positive and negative streamers are studied in ambient air at 1 bar; they emerge from a
needle electrode placed 40 mm above a planar electrode. The amplitudes of the applied …

We simulate short positive and negative streamers in air at standard temperature and
pressure. First, double-headed streamers in homogeneous electric fields of 50 kV cm− 1 are …

We present an open-source plasma fluid code for 2D, cylindrical and 3D simulations of
streamer discharges. The code is based on the Afivo framework, which features adaptive …

Positive streamers are thought to propagate by photo-ionization; the parameters of photo-
ionization depend on the nitrogen: oxygen ratio. Therefore we study streamers in nitrogen …

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 …

The paper discusses the relation between streamer velocity and diameter that follows from
an analytical approach to description of the streamer head structure. It is shown that using …
