Simulation of meteorological field variations associated with changes in different-level cloud formation conditions
Numerical experiments have been performed in order that the response of the surface thermobaric fields to changes in the formation conditions of different-level clouds be investigated. On the average, a 20% increase of the coupling coefficient between the amount of low clouds and relative humidity leads to an increase in...

The role of ocean dynamics in the Arctic water contamination
Using a rough resolution model of the ice-ocean interaction and seasonal atmosphere climate data, the main feature of the Arctic ocean circulation and ice drift were reproduced. On the basis of the restored dynamics the transport of contaminated materials from the Yenisey river mouth in the Kara Sea was investigated...

Application of a three-dimensional numerical model for estimation of atmosphere pollution with mountain-valley circulation
The paper deals with the problem of dispersing some polluting substances on the basis of application of a three-dimensional hydrodynamic model. A brief description of the model is given. The real profiles of wind velocity are used for the calculation of dispersing fields. This enables us to reveal peculiarities of...

Simulation of atmospheric methane distribution after releasing methane caused by plausible destabilization of methane hydrates
Methane possesses the radiative efficiency higher than that of carbon dioxide. To estimate the potential impact of the change in the global distribution of methane concentration - due to CH4 emission from marine sediments of the continental shelf - on climate, scenario calculations were carried out.

The North Pacific variability during 1981-1991: modeling and comparison with the reanalysis and satellite data
The development of realistic ocean circulation models may improve our understanding of the ocean processes and enable the prediction of the ocean response to the external forcing. The reanalysis and satellite data may be selected as control data for the simulated variations of the temperature fields on the surface. The...

Dust transport from industrial cities to large distances
It is well known that industrial centers are powerful sources of emission into the atmosphere of lot of pollutants transported with aerosol particles. As a result, the formation of antropogenically changing bio-geochemical provinces takes place. There are some examples of air pollution investigations in the vicinity of industrial centers, but...

On possible increase of the methane flux into the atmosphere from the destabilized methane-hydrates under changes of the ocean surface temperature
The possibility of methane-hydrate decomposition due to global climate changes is investigated using the world ocean model. It is supposed that the temperature of the ocean surface rises up to 1.5º during 50 years and then decreases to 1.5º. The climatic model of the ocean is integrated for the period...

Coordinate transformation for a small-scale meteorological model
A terrain-following coordinate transformation is introduced into a small-scale meteorological model by using a variational approach based on the Hamiltonian principle. The coordinate transformation is explicitly formulated in the corresponding Lagrange function. In this way, limitations on orography steepness can be easily obtained. An example of a mountain wave calculation...
