Abstract

Behavior of climate system (CS) of Siberia was studied with regard to structural transformations and reorganization of atmospheric processes. New approach to description of CS modification with using integral estimation functions and the model of weather formation has been developed. This approach allows us to anlayze features of time-spatial changes of climate, to ascertain dominating factors and to reveal cause-effect relatins. Analysis of instrumental data permits us to describe Siberia climate changes and features of modifications of weather forming regimes at transformation of pressure field. It is shown that Atlantic air masses forms the warm and moisture advection regime and provide the warming at winter searson. Abnormal processes of circulation transformations into summer type and atmospheric vortexes motion, which formed different climate forming factors and weather regimes at regions, have been investigated. Physical processes and mechanisms of regional CS states transformation are discussed.
