On a penetrating radiation from thunderclouds [PDF]

Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1933
Abstract The possibility of the production of fast β-rays by a charged thundercloud has been discussed by Professor C. T. R. Wilson, who has shown that such a cloud should spray upwards a stream of “runaway electrons” of energy as high as 5 × 109 electron-volts. The action of the earth’s magnetic field upon this stream should cause it

Polarization Measurements and Source Locations of Saturn Electrostatic Discharges During the Voyager Era

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract A Saturn Electrostatic Discharge or SED is an intense electromagnetic impulse induced by Saturn lightning, which escapes into space through the magnetoplasma of the ionosphere. Since previous SED polarizations from Voyager data are inconclusive, this polarization study is the first which properly considers the characteristics of the Voyager ...

Stratosphere‐Troposphere Exchange of Ozone and CO Over the North Pacific: Roles of Different Types of Rossby Wave Breaking With Multiple Chemical‐Reanalysis Perspectives

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract In this study, we investigate the characteristics of stratosphere‐troposphere exchange (STE) of ozone and carbon monoxide (CO) over the North Pacific on the 350 K isentropic surface during 2005–2021 using two chemical reanalyses (Copernicus Atmosphere Monitoring Service and TCR‐2).

Simulation on the development progress of positive glow corona discharge from ground wire of AC/DC transmission lines under thunderstorm condition

The Journal of Engineering, 2019
In thunderstorm weather, lightning induction appears on the surface of ground objects, and then the positive glow corona is initiated, which influences the selection of lighting targets by lighting leader.

The Source Brightness Distribution of Terrestrial Gamma‐Ray Flashes From the ALOFT Flight Campaign

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Terrestrial Gamma‐ray Flashes (TGFs) are naturally occurring phenomena that consist of bursts of gamma radiation associated with thunderclouds. Measurements of TGFs have been predominantly based on satellite instruments due to the significantly larger observation area compared to ground measurements. Due to atmospheric attenuation of the gamma

Space-temporal structure of the thunderstorm ground enhancements (TGEs)

Physics Open
We analyzed the structure of the Thunderstorm Ground Enhancement (TGE) using a particle detector network on Aragats. We performed a statistical analysis of the particle arrival time series on a nanosecond time scale using the largest TGE event on record,

On the impact of thunder on cloud ice crystals and droplets [PDF]

Atmospheric Chemistry and Physics
Calculations are presented on the impact of thunder on cloud particles. The results show that the creation of a shock wave front near a lightning channel results in shattering of ice crystals, droplets, and dust aerosols, this being a yet unidentified ...

HF Lightning Observations in the Upper Volga Region of Russia

Atmosphere
Much of the information for studying the processes of lightning discharge initiation and development is provided by studying thundercloud radio emissions in various frequency bands.

Penetrating Radiation from Thunderclouds [PDF]

Nature, 1933
IN their recent paper1 B. F. J. Schonland and J. P. T. Viljoen throw doubts on the ability of ionisation methods to detect the penetrating radiation from thunderclouds. However, this method has been in use at this station during the thunderstorm season October 1932–April 1933 with practically the same results as those obtained by Schonland and Viljoen.
