Analysis of dynamic properties of Siberia climatic system

摘要

The results of analysis of climatic system dynamic properties, which manifest themselves in temporal changeability features of atmosphere states, meteorological fields and phenomena, weather regimes and rhythms, are presented Changeability of climate forming factors and climate rhythms is considered in correlation with transformations of the environment and interrelation between the geosphere elements. A system-evolutionary approach to describe climatic changes in the context of multilevel model with the use of the information about different objects and processes of different levels has been evolved. New techniques of coupling analysis of changeability of environment, state ensemble, and intersystem relations in geosphere were developed. Special dynamics types such as long-term oscillations and directional climatic changes, which are caused by partly reversible transformations of relations, were revealed and studied. The mechanism of climate process reorganization due to the media transformation in the atmosphere and in the ocean with the subsequent formation of ice cover in North seas, which leads to changes in interrelations of the Ocean-Atmosphere-Land system, heat-mass exchange, the atmospheric circulation, and weather formation regimes, has been discovered.
