Abstract

The methods and means of the system-evolutionary analysis of mesoclimate state ensemble in multidimensional phase space of meteorological variables provide new opportunities for estimation of features of climate changes. The method of graphic climate representation includes procedures of processing of meteorological data, calculation of the estimation characteristics and construction of meteorological portraits. The techniques of the analysis use procedures of identification of particular areas in state space for long-term intervals, determination of the variability characteristics of the state ensembles. The characteristics of interdecadal and long-term variability of Siberian mesoclimate were obtained. The features of changes in relations between surface processes and atmospheric climate processes, variation of periodicity and violation of climate rhythm synchronism at the transition stages, tendencies to temperature and precipitations growth during cold period and an increase in the duration of warm periods are revealed.
