【 摘 要 】

The methodical approach to an assessment of trends of long-range pollution of atmosphere for the ecologically significant zones in view of predicted climatic changes is formulated. Zonal and meridional pollution indices are introduced, which characterize the amount of transported impurities in the latitudinal and meridional directions. The features of the dynamics of long-range atmospheric pollution of the territories of the Russian Federation (RF) under current conditions, in the immediate and distant prospects taking into account the changing climate (from 1980 to 2050) are studied. The results indicate for some strengthening in 2015-2050 compared to the period 1980-2015 the contribution of the west-eastern impurity transport to atmospheric pollution over the northwestern part of the European territory of Russia (ETR), the center of Western and Eastern Siberia, most of the Far East and the Arctic zone of Russia above 70° N and the contribution of the southern impurity transport to atmospheric pollution over the center and southern part of the ETR and the southeastern territories of the Far East. These results are important for the development of proposals for ensuring the environmental safety of Russian regions and for planning economic development of the country's territories that affect the pollution of the environment of ecologically significant zones.
