Abstract
The paper presents the analysis of the influence of the lower stratiform clouds (Sc, St, Ns) on long-term changes in surface temperature, performed for Siberia using the results of zoning of the territory according to cloudiness conditions. It has been shown that there is a weakly marked increase in the amount of low stratiform clouds during all seasons in the last 45-year period (from 1969 to 2013), which is accompanied by a quite noticeable increase in the surface temperature, especially in the polar regions.
