## Simulation of seasonal geographic patterns of methane using observation data

The three-dimensional global climatic model is employed as a tracer transport model to the study of atmospheric distributions of methane. Methane is input at appropriate surface grid points. The 4-year model experiment was run using sparse observed data at 19 sampling sites for the period 1984-1987, by which time a...

## The use of satellite remote sensing data in numerical modeling of the North Pacific circulation]

A numerical model constructed in the Institute of Computational Mathematics and Mathematical Geophysics (the former Novosibirsk Computing Center), based on the finite element method has been used for investigation of the sensitivity of the Pacific ocean circulation to a climatic (Hellerman and Rosenstein) and satellite derived (Halpern et al.) wind...

## A qualitative theory to explain the fractal properties of convective turbulence

The hydrodynamics statistical model which qualitatively explains the fractal features of the atmospheric convection has been suggested.

## On sensitivity of the World Ocean model to the vertical resolution

The three-dimensional linear model of the World ocean climate (with real bottom) is presented. The numerical method is based on the implicit schemes. The equations of heat and salt transport with respect to horizontal coordinates are approximated by the nine-point difference scheme, obtained by the Richardson extrapolation. The second up-wind...

## A difference algorithm for a small-scale non-hydrostatic meteorological model

A numerical scheme for the advection part of a small-scale mathematical-meteorological model developed earlier is proposed. The algorithm has a technical advantage when dealing with implicit difference schemes. The flow produced by the meteorological model serves as a basis for the calculation of pollutant transport over complex terrain. A simple...
