The paper focuses on the differentiations between large clasters of thunderstorms and a smaller ones such as supercells. The analysis was also enriched by DEMETER flybys, which granted us with a better insight into the origin of these phenomena. The main conclusion from the paper shows that the more condensed in a matter of size the thunderstorm is the stronger discharges it generates.

One of the fundamental tasks of atmospheric physics is the study of the processes of vertical interaction of atmospheric layers. We carried out observations with a Fabry-Perot interferometer at an altitude of 90-100 km. We have shown that sudden stratospheric warming and active planetary waves have an impact on the dynamics of the upper atmosphere. Namely, the green line airglow decreases, and the temperature rises. Major warming causes the reversal of the zonal wind in the upper atmosphere.

It is a continuation of my works published by the Annales Gephysicae in 2016–2020. In this work, a new method for analyzing experimental data is proposed, calculations have been carried out, and a new class of distributions of particles of radiation belts has been constructed. As a result of this work, new, more finer physical regularities of the structure of the Earth's proton radiation belt and its solar-cyclic variations were obtained, which cannot be obtained by other methods.

Numerical modeling is used to simulate atmospheric circulation and calculate residual mean meridional circulation (RMC) during sudden stratospheric warming event (SSW). Calculating the RMC is used to take into account wave effects on transport of atmospheric quantities and gas species in the meridional plane. The results show that RMC undergoes significant changes at different stages of SSW and also contribute to the SSW development.

Boundaries in the plasma around comet 67P separate regions with different properties. Many have been identified, including a new boundary called an infant bow shock. Here, we investigate how the plasma and fields behave at this boundary and where it can be found. The main result is that the infant bow shock occurs at intermediate activity and intermediate distances to the comet. Most plasma parameters behave as expected, however some inconsistencies indicate that the boundary is non-stationary.
