Abstract

Results of numerical simulation, devoted to the investigation of the influence of the Earth's relief on the circulation of the lower and middle atmosphere, are presented. The main attention is focused on the influence of an isolated mountain array on the circulation of the lower and middle atmosphere in the vicinity of this array. Mountains and rocks, covering the Kerguelen archipelago, are selected to be the isolated mountain array.
