Results of climate changes with variability of climate formation factors at the Asian territory of Russia are presented. The variability of spatio-temporal distribution of temperature, radiative and heat balance components, variability of cloud cover, cyclonic activity, and influence of large-scale circulation on temperature variability are investigated. It is shown that over the territory for this period the positive trend of annual averaged temperature is 0.34°C/decade with higher values in some months. For West and East Siberia the process of weakening of west transfer blocking, described by SCAND index, has a major contribution. For Far East, circulation processes in the northern Pacific Ocean play a dominating role. Annual averaged radiative balance values at the top are negative; it is in consistent with negative annual averaged air temperature, averaged over territory. Obtained regression models allow us to describe up to 65% of temperature variability using both circulation and radiative factors.
