The Impulsive Nature of Lightning Initiation [PDF]

, 2021
<p>We report results from imaging the initiation region of lightning via 3D interferometric beamforming on data collected by the Netherlands-based core of the Low Frequency Array of Antennas (LOFAR). LOFAR achieves 1 nanosecond timing accuracy and meter-scale spatial precision in lightning imaging on pulses observed in the 30-80 MHz band ...

Global distribution of winter lightning: a threat to wind turbines and aircraft [PDF]

Natural Hazards and Earth System Sciences, 2016
Lightning is one of the major threats to multi-megawatt wind turbines and a concern for modern aircraft due to the use of lightweight composite materials. Both wind turbines and aircraft can initiate lightning, and very favorable conditions for lightning

In-cloud discharge of positive cloud-to-ground lightning and its influence on the initiation of tower-initiated upward lightning [PDF]

Journal of Geophysical Research: Atmospheres, 2021
The data supports the manuscript entitled “In-cloud discharge of positive cloud-to-ground lightning and its influence on the initiation of tower-initiated upward lightning,” and MATLAB can open these *.mat files. The *.mat contains waveforms of fast electric field change, slow electric field change, VHF waveform, and located radiations. The data *.cine

Polarimetric radar characteristics of lightning initiation and propagating channels [PDF]

Atmospheric Measurement Techniques, 2019
In this paper we present an analysis of a large dataset of lightning and polarimetric weather radar data collected in the course of a lightning measurement campaign that took place in the summer of 2017 in the area surrounding Säntis, in the northeastern

Lightning at Jupiter pulsates with a similar rhythm as in-cloud lightning at Earth

Nature Communications, 2023
Our knowledge about the fine structure of lightning processes at Jupiter was substantially limited by the time resolution of previous measurements. Recent observations of the Juno mission revealed electromagnetic signals of Jovian rapid whistlers at a ...

Numerical simulation of the effect of atmospheric condition on the lightning strike for wind turbine

Frontiers in Earth Science, 2023
The risk of lightning exposure increases as wind turbine size increases, and lightning accidents have grown up to be a severe threat to wind turbines. The present paper focuses on the influence of the changes in atmospheric conditions around the rotating

Initiation of lightning flashes simultaneously observed from space and the ground: Narrow bipolar events [PDF]

, 2022
We investigate the initiation of four lightning flashes detected from ground by means of the Colombia Lightning Mapping Array (Colombia-LMA) and simultaneously observed from space by the optical sensors of the Atmosphere-Space Interactions Monitor (ASIM)

A distinct negative leader propagation mode

Scientific Reports, 2021
The common phenomenon of lightning still harbors many secrets such as what are the conditions for lightning initiation and what is driving the discharge to propagate over several tens of kilometers through the atmosphere forming conducting ionized ...

Dependence of Warm Season Cloud-to-Ground Lightning Polarity on Environmental Conditions over Sichuan, Southwest China

Advances in Meteorology, 2021
The effects of thermodynamic and moisture factors on cloud-to-ground (CG) lightning polarity in the warm season were discussed. Small convective available potential energy (CAPE) represents relatively shallow convection, which is beneficial to the ...
