Change of processes in a climate system at transformations of a space-structure organization and relations between climate forming components have been investigated in the frameworks of conception of energy transformation and energy-mass transfer in geosphere. The interrelations between the Atmospheric Action Centers, moving baric systems, and energy transforming systems of surface affect on energy-mass transfer in the atmosphere through the circulation mechanism and energy-mass exchange. A system-evolutionary approach to description and analysis of climatic changes with the use of the graphic models of information about different objects and processes of different levels has been evolved. Techniques of coupling analysis of changeability of environment, baric systems, weather-forming regimes, and intersystem relations in the geosphere were developed.
Results of the instrumental data processing, the coupling analysis of baric system transformations, meteorological variables fields, and the weather forming regimes are shown for typical situations for Siberia. Mechanisms of energy exchange and basic energy transforming processes for different types fo dynamics of air mass movement above the continent have been investigated. The peculiarities of energy-mass exchange in moving air masses, conditions and physics of processes of forming peculiar phenomena have been revealed: the winter thaws, the oscillations of weather forming in transitional seasons, the forced snow melting, summer droughts.
