The paper reviews work on investigation into the influence of A(ores High and its evolution on the stratospheric and tropospheric meteorological parameters and total ozone (TO) in Europe and their evolution. Preliminary results have been obtained that indicate the close relationship between regions with minimum TO and the Siberian anticyclone. Based on 105-year observations of the Siberian anticyclone parameters, the sharp pressure rise in the center of the anticyclone has been revealed recently. It has also been found that the center of pressure travels to the west.
