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 ...

Constraints to do realistic modeling of the electric field ahead of the tip of a lightning leader. [PDF]
J Geophys Res Atmos, 2017 Several computer models exist to explain the observation of terrestrial gamma-ray flashes (TGFs). Some of these models estimate the electric field ahead of lightning leaders and its effects on electron acceleration and multiplication.

Using Lightning Flashes to Image Thunderclouds. [PDF]
J Geophys Res Atmos, 2019 AbstractThe optical energy emitted by lightning flashes interacts with the surrounding cloud medium through scattering and absorption. The optical signals recorded by space‐based lightning imagers describe a convolution of lightning flash energetics and radiative transfer effects in the intervening cloud layer.

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

Energetic Charged Particles Above Thunderclouds [PDF]
Surveys in Geophysics, 2012 The French government has committed to launch the satellite TARANIS to study transient coupling processes between the Earth’s atmosphere and near-Earth space. The prime objective of TARANIS is to detect energetic charged particles and hard radiation emanating from thunderclouds. The British Nobel prize winner C.T.R.

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 ...

Continental thunderstorm ground enhancement observed at an exceptionally low altitude [PDF]
Atmospheric Chemistry and Physics, 2022 Two long-lasting thunderstorm ground enhancement (TGE) events were registered at the Milešovka meteorological observatory in Czechia (50.55∘ N, 13.93∘ E; 837 m altitude) on 23 April 2018, during linearly organized thunderstorms.
