Electromagnetic atmosphere-plasma coupling: the global atmospheric electric circuit [PDF]

open access: yes, 2011
A description is given of the global atmospheric electric circuit operating between the Earth’s surface and the ionosphere. Attention is drawn to the huge range of horizontal and vertical spatial scales, ranging from 10−9 m to 1012 m, concerned with the ...

High-altitude electrical discharges associated with thunderstorms and lightning [PDF]

open access: yesJournal of Atmospheric and Solar-Terrestrial Physics, 2015
The purpose of this paper is to introduce electrical discharge phenomena known as transient luminous events above thunderstorms to the lightning protection community. Transient luminous events include the upward electrical discharges from thunderstorms known as starters, jets, and gigantic jets, and electrical discharges initiated in the lower ...

Development of novel hybrid machine learning models for monthly thunderstorm frequency prediction over Bangladesh

open access: yesNatural Hazards, 2021
Thunderstorm frequency (TSF) prediction with higher accuracy is of great significance under climate extremes for reducing potential damages. However, TSF prediction has received little attention because a thunderstorm event is a combination of intricate ...

Twentieth century secular decrease in the atmospheric potential gradient [PDF]

open access: yes, 2002
Current flowing in the global atmospheric electrical circuit (AEC) substantially decreased during the twentieth century. Fair-weather potential gradient (PG) observations in Scotland and Shetland show a previously unreported annual decline from 1920 to ...

Experimental Evidence of Giant Electron - Gamma Bursts Generated by Extensive Atmospheric Showers in Thunderclouds

open access: yes, 2004
The existence of a new phenomena - giant electron-gamma bursts is established. The bursts are generated in thunderclouds as a result of the combined action of runaway breakdown and extensive atmosphere showers (RB-EAS).
