Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical 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.

Propagation of positive, negative, and recoil leaders in upward lightning flashes

open access: yesEarth and Planetary Physics, 2019
Leader propagation is a fundamental issue in lightning physics. The propagation characteristics of positive leaders and negative leaders are summarized and compared based on data from high-speed camera and electromagnetic field in rocket-triggered ...

Fast and Fine Location of Total Lightning from Low Frequency Signals Based on Deep-Learning Encoding Features

open access: yesRemote 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 ...

Luminosity and Current Characteristics of Metal-vaporized Channel of an Artificially Triggered Lightning

open access: yes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]

open access: yes, 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

Application of Genetic Algorithm to Estimation of Function Parameters in Lightning Currents Approximations

open access: yesInternational Journal of Antennas and Propagation, 2017
Genetic algorithm (GA) is applied for the estimation of two-peaked analytically extended function (2P-AEF) parameters in this paper. 2P-AEF is used for approximation of measured and typical lightning discharge currents.

Luminous pulses during triggered lightning [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2012
A triggered lightning flash that transferred negative charge to ground in central New Mexico produced more than three levels of branching above the main channel to ground in a 1 km vertical field of view. A high‐speed video recording shows that the main channel had about 50 brief luminous pulses, many of which were superimposed on a slowly changing ...

Lightning for Energy and Material Uses: A Structured Review

open access: yesGlobal Challenges, 2020
The average atmospheric charge density of Earth is neutral. Charge built up from thunderstorms and lightning phenomena is offset by oceanic surface charging, and offers a source of energy that has not been harnessed broadly.
