Regional features of thunderstorm activity (on the example of the territory of the Kabardino-Balkarian Republic)

Наука. Инновации. Технологии, 2023
Introduction. Thunderstorm activity refers to one of the regional climatic characteristics of a limited area. Thunderstorms result in lightning discharges and an increase in the electric field strength of the surface layer of the atmosphere.

Where numerical weather prediction meets large‐eddy simulations in a convective boundary layer during the FESSTVaL field experiment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We exploit the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL) to compare the performance of an NWP model at sub‐km resolutions with a traditional LES model. Focusing on clear‐sky ABL turbulence (June 14), shallow convective clouds and surface radiation (June 27), and deep convective cold pools (June 29), we find ...

Experimental Evidence of Giant Electron - Gamma Bursts Generated by Extensive Atmospheric Showers in Thunderclouds

, 2004
The existence of a new phenomena - giant electron-gamma bursts is established. The bursts are generated in thunderclouds as a result of the combined action of runaway breakdown and extensive atmosphere showers (RB-EAS).

Extreme weather caused by concurrent cyclone, front and thunderstorm occurrences

Scientific Reports, 2017
Phenomena such as cyclones, fronts and thunderstorms can cause extreme weather in various regions throughout the world. Although these phenomena have been examined in numerous studies, they have not all been systematically examined in combination with ...

Evaluation of the WRF model for simulating deep convection and cold‐pool characteristics relevant to wind‐energy applications in Germany

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Deep convection and cold‐pool characteristics over Germany during July 2023 are investigated using Deutscher Wetterdienst (DWD) radar observations and a Weather Research and Forecasting (WRF) model simulation. The temporal evolution of convective cell features reveals a downward‐facing parabolic pattern in both WRF and observations, in terms of cell ...

Application of Seq2Seq models for predicting the development of thunderstorm activity to enhance the pilot’s situational awareness in flight

Научный вестник МГТУ ГА
The paper presents the results of application of Seq2seq models based on neural networks for nowcasting-forecasting with a lead time of up to 2 hours – of thunderstorm activity in order to increase situational awareness of aircraft crews.

Moist convection and radiative cooling: Dynamical response and scaling

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The mechanism that sets the updraught velocities in deep convective clouds is studied here using cloud‐resolving model simulations in radiative–convective equilibrium. We show that, for simulations with vastly different rates of radiative cooling and surface temperatures, the buoyancy in clouds remains remarkably constant (histogram shown here).

Inversion of a Thunderstorm Cloud Charging Model Based on a 3D Atmospheric Electric Field

Applied Sciences, 2018
The measurement of the atmospheric electric field is of great significance for the study of thunderstorm cloud charge models. Traditional electric field meters can only measure the vertical component of the atmospheric electric field, and thus it is ...

Impact of Various Disturbance Sources on the Atmospheric Electric Field and Thunderstorm Activity of the Northern Tien-Shan

Atmosphere, 2023
Features of the manifestations of various sources of disturbances in the atmospheric electric field at the Tien-Shan high-mountain station have been studied, and the statistical relationship between solar and thunderstorm activity has been established ...

The stratospheric gravity wave field produced by a supercell

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Supercells are a class of long‐lasting thunderstorms with rotating updrafts that often cause severe weather, hail, and tornadoes. This study uses numerical simulations to characterize the stratospheric gravity waves that are caused by these storms.
