Compact intracloud lightning discharges: 2. Estimation of electrical parameters
[1] We estimated electrical parameters of 48 located compact intracloud discharges (CIDs) using their measured electric fields and vertical Hertzian dipole approximation. This approximation is consistent with the more general bouncing‐wave CID model for a reasonably large subset of allowed combinations of propagation speed and channel length. For nine events, we estimated channel lengths from o...
متن کاملOn phenomenology of compact intracloud lightning discharges
[1] We examined wideband electric fields, electric and magnetic field derivatives, and narrowband VHF (36 MHz) radiation bursts produced by 157 compact intracloud discharges (CIDs). These poorly understood lightning events appear to be the strongest natural producers of HF‐VHF radiation. All the events transported negative charge upward (or lowered positive charge), 150 were located by the U.S....
متن کاملModel of red sprites due to intracloud fractal lightning discharges
A new and improved model of red sprites is presented. Emphasis is placed on accounting for the puzzling observation of the spatial structure in the exnissions. The model relies on the electromagnetic pulse (EMP) fields created by a horizontal lightning discharge and includes the observed fractal structure of such discharges in the computation of the EMP power density. It, is shown that the mode...
متن کاملJoint radio and optical observations of the most radio-powerful intracloud lightning discharges
The most radio-powerful intracloud lightning emissions are associated with a phenomenon variously called “narrow bipolar events” or “compact intracloud discharges”. This article examines in detail the coincidence and timing relationship between, on the one hand, the most radio-powerful intracloud lightning events and, on the other hand, optical outputs (or lack thereof) of the same discharge pr...
متن کاملHigh-altitude electrical discharges associated with thunderstorms and lightning
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 ionosphere such as sprites, halos, and elves. We gi...
