A New Electric Field Mill Network to Estimate Temporal Variation of Simplified Charge Model in an Isolated Thundercloud [PDF]
Sensors, 2022 The gross charge distribution in an electrified cloud has already been estimated by polarity distribution of the electrostatic field on the ground surface.

Investigation of Thundercloud Features in Different Regions [PDF]
Remote Sensing, 2021 A comparison of thundercloud characteristics in different regions of the world was conducted. The clouds studied developed in India, China and in two regions of Russia. Several field projects were discussed. Cloud characteristics were measured by weather

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 ...

Relay charge transport in thunderclouds and its role in lightning initiation [PDF]
Scientific Reports, 2022 A new mechanism of charge transport inside a thundercloud is suggested and numerically investigated. The considered mechanism can be called “relay” because it is provided by a dynamical network of a relatively small amount of continuously decaying and ...

From decimeter-scale elevated ionic conductivity regions in the cloud to lightning initiation [PDF]
Scientific Reports, 2021 In this work, we represent the lightning initiation scenario as a sequence of two transitions of discharge activity to progressively larger spatial scales: the first one is from small-scale avalanches to intermediate-scale streamers; and the second one ...

On the Electric Fields Produced by Dipolar Coulomb Charges of an Individual Thundercloud in the Ionosphere [PDF]
Journal of Astronomy and Space Sciences, 2015 In this paper we study the transmission of the electrostatic field due to coulomb charges of an individual thundercloud into the midlatitude ionosphere, taking into account the total geomagnetic field integrated Pedersen conductivity of the ionosphere.

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.

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 ...

Polarity transitions of narrow bipolar events in thundercloud tops reaching the lower stratosphere [PDF]
Nature CommunicationsBlue corona discharges are often generated in thunderclouds penetrating into the stratosphere and are the optical manifestation of narrow bipolar events (NBEs) observed in radio signals.
