We analyzed the unique episode of long-range dust/sand atmospheric aerosol transport from the arid zones of the southern European territory of Russia, i.e. the Northern Caspian and Astrakhan regions and the Kalmykia Republic, to the Moscow region dur

The possible existence of distinct regimes of barotropic circulation in closed annular channels at the same external parameters governing the flow dynamics is investigated both experimentally and numerically. Transitions between the regimes are reali

Helicity is inherent in many circulating motions and structures in the atmospheric boundary layer (ABL), where it is continuously reproduced due to the combined action of the Earth’s rotation and friction, which also is closely related to the pheno
The study was carried out using observations in a 5 km long and 200-300 m wide patch of loose sands, located west of the Naryn Khuduk settlement (Russia, 2013-2021). The uniqueness of this area is determined, in particular, by the structure of the Se

An analytical approach to the determination of optimal disturbances is developed. The approach, suitable for flows with piecewise-constant vorticity distributions, is based on the equation of disturbance energy balance and explicit expressions for th

The article analyzes difficult to explain experimental data on acoustic signals recorded from explosions and injections of matter at heights of 120–150 km. It is noted that a significant part of the acoustic energy of high-altitude explosions reach

Spatially periodic vortex systems that form due to unstable shear flows are called vortex streets. A number of exact and asymptotic solutions of two-dimensional hydrodynamic equations describing nonstationary vortex streets have been constructed. It
