Abstract:

The results of analysis of average monthly trend anomalies of air temperature in the atmospheric boundary layer are submitted. The data of radiosonde observations of 10 aerological stations in territory of the Siberian region over 1981-2010 (for January) and 1980-2009 (for July) were used. It has been found that in winter period the negative trends (for the most part from -0.6 to -0.8°C/10 years) are present in the temperate latitudes (50-60°N) of Western Siberia against the background of general domination of positive trends in the examined territory. Comparison of air temperature anomalies for the last and preceding decades was done. According to it, in the beginning of ХХI century, the considerable deceleration of climates warming in the atmospheric boundary layer or even its cooling are marked in the both seasons over all the Siberian territory.
