This paper discusses the results of calculations of the climatic river runoff for the subarctic East Siberia region obtained by the linear reservoir model. For the verification of the model, the measurements data as well as the MERRA reanalysis data for the XXth century were used. For the XXIst century...

In a number of papers, it is shown that the ocean currents velocity considerably affects the interaction between the atmosphere and the ocean in the regions where currents are sufficiently strong. In this paper, the influence of the ocean currents on its response of the atmosphere to changes in CO...

We have simulated the influence of the Lena River heat and fresh water ux on the Laptev Sea shelf water state based on the coupled regional ocean-ice model and the subsea permafrost model. The numerical results show the variability of the summer hydrological fields on the shelf caused by the...

The auras of technogenic pollution of the snow cover observed from the space, and their dependence on the current weather conditions are investigated. On an example of emissions of weighed substances from the Iskitim cement plant, the numerical reconstruction of fields of losses of dust is carried out. For the...

A non-stationary mathematical model of the bio-aerosols dynamics is considered. It is stated as the initial boundary value problem for integral-differential equation, describing the particle size spectrum dynamics with respect to coagulation, condensation and evaporation processes. The numerical scheme for solving the equation is presented. It is based on the...

A nonlinear model of the saturated granular media based on a two-phase mixture model of viscous liquids is proposed. A mathematical model of the two-velocity dynamics of a granular medium involves the temperature phase equilibrium and the absence of the pressure phase equilibrium and is consistent from the thermodynamic standpoint...

A system of the Burgers equations of the two-velocity hydrodynamics is obtained. We consider the Cauchy problem in the case of a one-dimensional system. The estimate of the stability of the solution is obtained. We have obtained a formula for the Cauchy problem for the one-dimensional system of equations that...

Using the reconstruction models, the methods for the joint analysis of satellite and contact observations of the snow cover pollution ghosting in the vicinity of sources of dust have been developed. Based on numerical data analysis of the ground monitoring and satellite imagery, stable quantitative relationships between the falling dust...
