Introduction

Abstract

The major advance in the thermospheric and ionospheric physics has been taking place in recent decades on the grounds of the active development of the mathematical modelling of the upper atmosphere of the Earth representing a complex, multicomponent inhomogeneous gas system. The mathematical modelling of the atmosphere is a tool of its study based on the numerical calculation of the equations describing the spatial-temporal distribution of the medium parameters. It comprises the physical recognition of the problem; mathematical substantiation of the modelling equations, of the boundary and initial conditions; the choice or working out of the method and the algorithm of the solution of the obtained set of equations; constructing, testing and debugging of the model’s software; calculations, data processing and analysis of the results.
