Thundercloud electrification models in atmospheric electricity and meteorology [PDF]

A survey is presented of presently-available theoretical models. The models are classified into three main groups: (1) convection models, (2) precipitation models, and (3) general models. The strengths and weaknesses of the models, their dimensionalities

Post-return stroke VHF electromagnetic activity in north-western Mediterranean cloud-to-ground lightning flashes [PDF]

Atmospheric Chemistry and Physics
We investigate properties of the electromagnetic activity following the first lightning return stroke (RS), using concurrent observations from the SLAVIA (Shielded Loop Antenna with a Versatile Integrated Amplifier) sensor, the SAETTA (Suivi de l ...

Stepped Leader Progression and Speed Evolution in a Thunderstorm: Theoretical Model

Energies, 2019
This paper presents a theoretical model to describe the progression of leading (falling) lightnings in storms (stepped leaders). Stepped leaders move down from the thundercloud base to the encounter point with an upward streamer.

Solar modulation of atmospheric electrification through variation of the conductivity over thunderstorms [PDF]

It is suggested that variations of the current in the global atmospheric electrical circuit can be produced through regulation of the resistance between the tops of thunderclouds and the ionosphere.

Simulated Impacts of Thundercloud Charge Distributions on Sprite Halos Using a 3D Quasi-Electrostatic Field Model

Atmosphere
Sprite halos are transient luminous phenomena in the lower ionosphere triggered by tropospheric lightning. The effect of removed charge distributions on sprite halos has not been sufficiently discussed.

GRMLJAVINSKI OBLAK CUMULONIMBUS (CB) - ELEKTRIČNI GENERATOR [PDF]

, 2010
U radu se razmatra grmljavinski oblak Cumulonimbus (Cb) kao električni dipol i njegovo sudjelovanje u izgradnji atmosferskog električnog polja. Razmatranje je ograničeno na Cb s elektrostatskim unutarnjim stanjem tj.

Charging Thunderclouds Affect Ionospheric Conductivity

Eos, 2019
As thunderstorm updrafts strengthen, electrification of clouds can heat the lower ionosphere, explaining prolonged disturbances to radio waves in the rarefied atmospheric layer.

Rapid evolution of energetic lightning strokes in Mediterranean winter storms

npj Climate and Atmospheric Science
The occurrence of winter lightning concentrates in a few specific regions in the world, including the Mediterranean, where electromagnetic signatures of this interesting dangerous phenomenon have not yet been studied in detail. We investigate the initial
