Dancing Sprites Above a Lightning Mapping Array—An Analysis of the Storm and Flash/Sprite Developments [PDF]

Journal of Geophysical Research: Atmospheres, 2021
Abstract One of the most enigmatic types of sprites is the dancing sprite which appears to dance above the storm as sequential luminous emissions a few 100 ms or less apart. Dancing sprites occur in relatively small proportion and many aspects of their generation remain unknown.

Internal Duality for Resolution of Rings [PDF]

, 1999
It has been argued in the technical literature, and widely reported in the popular press, that cosmic ray air showers (CRASs) can initiate lightning via a mechanism known as relativistic runaway electron avalanche (RREA), where large numbers of high ...

Preliminary Research on a Comparison and Evaluation of FY-4A LMI and ADTD Data through a Moving Amplification Matching Algorithm

Remote Sensing, 2020
In this study, a new moving amplification matching algorithm was proposed, and then the temporal and spatial differences and correlation were analysed and evaluated by comparing the FengYun-4A Lightning Mapping Imager (FY-4A LMI) data and the China ...

Analysis of charge transport during lightning using balloon‐borne electric field sensors and Lightning Mapping Array [PDF]

Journal of Geophysical Research: Atmospheres, 2007
Recently, wide band measurements of the electric field near a lightning flash have been obtained by a balloon‐borne electric field sonde or Esonde. This paper develops new techniques for analyzing lightning‐associated charge transport in a thundercloud by using both the Esonde data and simultaneous Lightning Mapping Array (LMA) measurements of VHF ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

Advanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Characteristics of the Preliminary Breakdown in Inverted-polarity Intracloud Lightning Flashes

应用气象学报, 2023
The intracloud (IC) flashes can be classified into normal and inverted-polarity types according to their initial leader propagation directions. Due to the rare occurrence of inverted-polarity IC flashes with downward preliminary breakdown (PB) processes,
