Citizen Science Observation of a Gamma‐Ray Glow Associated With the Initiation of a Lightning Flash

Geophysical Research Letters, 2023
Gamma‐ray glows are observational evidence of relativistic electron acceleration due to the electric field in thunderclouds. However, it is yet to be understood whether such relativistic electrons contribute to the initiation of lightning discharges.

An Experimental Study of Electromagnetic Field Propagation Due to Lightning Upward Leaders and Its Probability on Different Small-Scale Structures

Energies, 2022
In this paper, upward leader initiation and the probability of lightning flashes on different air terminal were analyzed in detail. With the growing global warming, lightning flash density has increased abruptly, especially in tropical countries.

An Initiation of Ball Lightning in an Aircraft

Journal of Atmospheric and Solar-Terrestrial Physics, 2021
Abstract The detailed observation of ball lightning in an aircraft gives strong evidence that the ball lightning was initiated by preceding corona from metallic diverter strips attached to the surface of the radome. These diverter strips are designed to direct current from a lightning strike to the radome towards the aircraft fuselage in order to ...

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

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

Numerical Simulation of Main Negative Charge Area Parameters for Upward Negative Cloud-to-ground Lightning

应用气象学报, 2020
Different types of lightning initiation condition are the focus of scientific research. The initiation of cloud lightning is competitive with self-sustaining uplink lightning.

Difference Between 2D and 3D Development Characteristics of an Upward Lightning Leader

应用气象学报, 2023
Tall object not only has a high probability of being struck by downward lightning, but also is easy to trigger upward lightning. Comparing with 2D optical observation, reconstructed 3D observation by dual-station optical observation can better reflect ...

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)

Luminosity of initial breakdown in lightning [PDF]

Journal of Geophysical Research: Atmospheres, 2013
Time correlated high‐speed video and electromagnetic data for 15 cloud‐to‐ground and intracloud lightning flashes reveal bursts of light, bright enough to be seen through intervening cloud, during the initial breakdown (IB) stage and within the first 3 ms after flash initiation. Each sudden increase in luminosity is coincident with a CG type (12 cases)
