#### Towards a Theory of Barotropic Geostrophic Currents

In this article, 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....

#### About a role of vegetation of deserts of Central Asia in climate change

This article focuses on the temperature of various underlying surfaces (rubble-rock on hamadas, sand on the beds of temporary **streams**, plants) in the southern steppes of Mongolia. The authors present a comparative analysis of soil and plant temperature and address the issue of the impact of overgrowing of desert areas on climate change on Earth.

#### Nutrient Fluxes from the Pregolya Catchment Area into the Vistula Lagoon

... emissions and diffuse load. The author applies the model of nutrient flux from the Pregolya River catchment area based on FyrisNP Version 3.1, which takes into account the catchment land use, nutrient runoff from point sources and lands of different types, **stream** characteristics, and precipitation.

#### The interaction between an anticyclone and barrier

The article considers the interaction of a two-dimensional anticyclone with a barrier and generates and solves its motion equation. The
authors claim that an anticyclone accelerates at the approach of the edge of a barrier forming an intensive **stream**. The article also offers
the streamline pattern analysis.
