Abstract:

The results of research of long-term changes of air humidity conditions of the atmospheric boundary layer observed over the territory of the Siberian region in the last 30 years are presented. It has been found that if in winter the positive trends of water vapor mixing ratio take place in the atmospheric boundary layer in Arctic area, and negative trends prevail on the rest of territory of the region, especially, in the south of Western Siberia, then in summer there are positive trends everywhere. In addition, it is discovered, that the noticeable weakening of growth rates of water vapor mixing ratio is marked in the first decade of ХХI century, and there is even its decrease in some regions.
