Remote Sensing, 2021 Lightning location provides an important means for the study of lightning discharge process and thunderstorms activity. The fine positioning capability of total lightning based on low-frequency signals has been improved in many aspects, but most of them ...

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

In-flight measurements of energetic radiation from lightning and thunderclouds [PDF]
, 2015 In the certification procedure aircraft builders carry out so-called icing tests flights, where the zero degree Celsius altitude is deliberately sought and crossed in or under thunderstorms. Airbus also used these flights to test ILDAS, a system aimed to

Lightning attachment processes of an “anomalous” triggered lightning discharge [PDF]
Journal of Geophysical Research: Atmospheres, 2014 AbstractUsing a high‐speed optical imaging system specifically designed for observing the lightning attachment process, we have documented the process for stepped, dart, and dart‐stepped leaders in an anomalous rocket‐triggered lightning flash that terminated on a 10 m grounded utility pole.

Wave Profile for Breakdown Waves with a Large Current Behind the Wave Front [PDF]
, 2017 For analytical solution of breakdown waves with a large current behind the wave front, we employ a one-dimensional, steady-state, three-component (electrons, ions, and neutral particles) fluid model.

The Review of Laser Engineering, 1991 Electrical discharge guided by a 100J/2GW pulse CO2 laser is reviewed. A long air break-down plasma channel is produced by using a Multi-Active CHannel (MACH) focusing mirror which has two focal lengthes. The plasma channel has been used to guide electrical discharge over a distance of 6m in laboratory air at an applied potential of-1.2MV. A successive

VHF lightning mapping observations of a triggered lightning flash [PDF]
Geophysical Research Letters, 2012 On 3 August 2010 an extensive lightning flash was triggered over Langmuir Laboratory in New Mexico. The upward positive leader propagated into the storm's midlevel negative charge region, extending over a horizontal area of 13 × 13 km and 7.5 km altitude. The storm had a normal‐polarity tripolar charge structure with upper positive charge over midlevel

应用气象学报, 2023 Channel current is an important parameter of the lightning discharge, but it's difficult to be directly measured due to the randomness and instantaneity of the natural lightning. The channel luminosity, however, is relatively easier to obtain.

Wave Profile for Anti-force Waves with Maximum Possible Currents [PDF]
, 2015 In the theoretical investigation of the electrical breakdown of a gas, we apply a one-dimensional, steady state, constant velocity, three component fluid model and consider the electrons to be the main element in propagation of the wave. The electron gas
