Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China

open access: yesHigh Voltage, EarlyView.
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

DC Side Impedance Modelling of an Actual Line Commutated Converter High Voltage Direct Current System and DC Resonance Characteristics

open access: yesHigh Voltage, EarlyView.
ABSTRACT The stability analysis of Line Commutated Converter High Voltage Direct Current (LCC‐HVDC) is of considerable engineering importance. Establishing its analytical mathematical model helps to analyse stability and the factors that affect stability of the system.

Comparison of lightning location data and polarisation radar observations of clouds [PDF]

open access: yes
Simultaneous observations of both the precipitation and the lightning associated with thunderstorms show that the lightning is within 3 km of the maximum precipitation echo.

Flash Detection Efficiencies of Long Range Lightning Detection Networks During GRIP [PDF]

open access: yes, 2012
We flew our Lightning Instrument Package (LIP) on the NASA Global Hawk as a part of the Genesis and Rapid Intensification Processes (GRIP) field program. The GRIP program was a NASA Earth science field experiment during the months of August and September,

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

open access: yesHigh Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

Lightning mapper development: Status and requirements [PDF]

open access: yes, 1984
The feasibility for the detection and location of lightning on a continuous basis using a sensor in geostationary orbit was established. Measurements of the optical characteristics of lightning and the capabilities of solid state mosaic focal plane ...

The Issue of Pre‐Islamic Arabic Christian Poetry Revisited

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Is only very little Arabic Christian poetry extant from pre‐Islamic times? While distancing myself from Louis Cheikho's (1859–1927) view that almost all pre‐Islamic poets were Christians, I contend in this article that some of them indeed were.

Sprites identification and their spatial distributions in JEM-GLIMS nadir observations

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2017
The Global Lightning and Sprite Measurements on the Japanese Experiment Module (JEM-GLIMS) started continuous nadir observations of lightning and transient luminous events (TLEs) at the International Space Station (ISS) in November 2012 and completed the
