Hydrodynamic approach to modeling non-stationary processes in ionospheric plasma

Zubkov E. V., Dedkov Y. V., Karataeva P. M., Khudenko V. N.

Based on an improved mathematical model of low-energy near-Earth space plasma, non-stationary problems of evolution of the ionosphere-plasmasphere system under various heliogeophysical conditions are considered. The model allows solving the complete system of hydrodynamic equations for nine kinds of ions and electrons, taking into account their heat balance, as well as the diffusion equations for metastable and small components. Based on the results of numerical modeling, the space-time distributions of the key macroscopic parameters of the ionospheric-magnetospheric plasma are obtained and analyzed.
