The analysis results of the long-term change trends of average seasonal temperature within the atmospheric boundary layer of Siberian region over 1981-2010 estimated by the observed data of 25 aerological stations for winter, spring, summer, and autumn are represented. It has been found that spring, summer, and autumn periods, but not winter (as it is adopted to consider), make the main contribution to the processes of regional warming for the noted last thirty years. It is shown that in the last ten years, when the trend to a slowdown of the global warming was exhibited, it becomes also apparent at a regional level as a result of the considerable drop of the average seasonal temperature in winter and summer, that is observed throughout the atmospheric boundary layer and almost all area of Siberian region.
