... of horizontal neutral wind and plasma heating by superthermal electrons. The article presents numerical calculation results of variations of charged particles concentration in the ionosphere and the plasmasphere. The comparative analysis of various hydrodynamic approximations for the description of the ionospheric and the magnetospheric plasma is carried out. It is made on the basis of the numerical solution of the system of equations of energy, continuity and motion for O+, H+ ions and electrons ...

One method for constructing exact solutions of equations of two-dimensional hydrodynamics of an incompressible fluid
We propose a simple algebraic method for constructing exact solutions of equations of two-dimensional hydrodynamics of an incompressible fluids.The problem reduces to consecutively solution three linear partial differential equations for a nonviscous fluid and to solving three linear partial differential equations and one first-order ordinary differential ...

Towards a Theory of Barotropic Geostrophic Currents
... we examine barotropic geostrophic currents in a Cartesian and the polar coordinate system. The polar system is preferable for analysing geostrophic currents, since radial symmetry is intrinsic to these currents. We obtained ratios between the general hydrodynamic properties. The expressions of geostrophic current velocity components in terms of pressure were the most important among them. The procedure of deriving the expression of vorticity in terms of pressure was carried out. We determined that ...

Inertial oscillations induced by the propagation of the Vis-tula Lagoon waters in the coastal zone of the Southeastern Baltic Sea
A mathematical model of the mechanism of anti-symmetric vortex at the confluence of fresh water to sea water, observed, in particular, the output of the Baltic Canal connecting Visla Lagoon to the Baltic Sea is constructed. It is shown in particular that the main reason the vortex formation in this case is the Coriolis force. Also analytically calculate the exact dependence of circula-tion rates from time to time for the three simplest forms of "language" of the intrusion of fresh water...
A study into the passive tracer and Lagrangian particles propagation in the coastal area of South-East Baltic

The geochemical characteristics of the bottom sediment in the pockmark area of the eastern part of the Gulf of Finland
... distribution of microcomponents in the bottom sediment indicates that the pockmark area is located in the geochemical barrier border zone where the reducing medium of the incoming mineralized solution meets the highly oxidizing sea water medium. The hydrodynamic and geochemical processes in the pockmark zone create focal areas of anomalous microenvironment and affect the composition and development of benthos.
