Similarity between the initial breakdown pulses of negative ground flash and narrow bipolar pulses

, 2014
In this paper, temporal characteristics of several initial electric field pulses of preliminary breakdown process (PBP) from very close negative cloud-to-ground (CG) flashes are compared to close narrow bipolar pulses (NBPs) to observe any similarity ...

The Characterization of Electric Field Pulses Observed in the Preliminary Breakdown Processes of Normal and Inverted Intracloud Flashes

Remote Sensing
We have studied the parameters of preliminary breakdown (PB) pulses in 395 normal and 319 inverted intracloud (IC) flashes observed in Gifu, Japan, and Ningxia, China, respectively, by using a low-frequency mapping system called fast antenna lightning ...

Lightning initiation: Strong pulses of VHF radiation accompany preliminary breakdown [PDF]

Scientific Reports, 2018
We analyze lightning initiation process using magnetic field waveforms of preliminary breakdown (PB) pulses observed at time scales of a few tens of microseconds by a broad-band receiver.

Time domain simulations of preliminary breakdown pulses in natural lightning [PDF]

Journal of Geophysical Research D: Atmospheres, 2015
AbstractLightning discharge is a complicated process with relevant physical scales spanning many orders of magnitude. In an effort to understand the electrodynamics of lightning and connect physical properties of the channel to observed behavior, we construct a simulation of charge and current flow on a narrow conducting channel embedded in three ...
