Electron acceleration above thunderclouds [PDF]
Environmental Research Letters, 2013 The acceleration of electrons results in observable electromagnetic waves which can be used for remote sensing. Here, we make use of ∼4 Hz–66 MHz radio waves emitted by two consecutive intense positive lightning discharges to investigate their impact on ...

Parameterizations for global thundercloud corona discharge distributions [PDF]
Atmospheric Chemistry and PhysicsFour parameterizations, distinguishing between land and ocean, have been developed to simulate global distributions of thundercloud streamer corona discharges (also known as Blue LUminous Events or BLUEs) mainly producing bluish optical emissions ...

Observation of gamma ray bursts at ground level under the thunderclouds
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2016 We observed three γ-ray bursts related to thunderclouds in winter using the prototype of anti-neutrino detector PANDA made of 360-kg plastic scintillator deployed at Ohi Power Station at the coastal area of the Japan Sea.

On the initiation of lightning in thunderclouds [PDF]
Scientific Reports, 2017 The relationship of lightning and elementary particle fluxes in the thunderclouds is not fully understood to date. Using the particle beams (the so-called Thunderstorm Ground Enhancements – TGEs) as a probe we investigate the characteristics of the ...

Thundercloud structures detected and analyzed based on coherent Doppler wind lidar [PDF]
Atmospheric Measurement Techniques, 2023 The studies of intracloud discharges may shed light on the microphysical structure of thunderclouds, as both the magnitude and the sign of charge separation due to graupel collides with ice crystals within the strong updrafts are influenced by the ...

Charge Density Distribution Model in Self-Organizing Cloud [PDF]
E3S Web of Conferences, 2020 The paper considers a charge distribution model in a thundercloud presenting a self-organizing system in view of its fractal structure. An analytical solution to the model equation is obtained. Using numerical calculations, the distribution of charges in

Numerical Model of Cloud-to-Ground Lightning for PyroCb Thunderstorms
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 This paper demonstrates a 2-D numerical model to represent two conceptual pyrocumulonimbus (pyroCb) thundercloud structures: i) tilted dipole and ii) tripole structure with enhanced lower positive charge layer, which are hypothesized to explain the ...

Thundercloud induced spatial ion flow in the neighborhood of rotating wind turbine and impact mechanism on corona inception [PDF]
, 2021 Lightning accidents seriously threaten the safe operation of wind turbines due to the unclear initiation mechanism of the airborne lightning-induced discharges on turbine blades, in which turbine rotation is one of the principal influencing factors.
