Phase variability of some characteristics of the present-day climate in the northern atlantic region

Study of the variability of the present-day climate based on statistical analysis of a century-long sequence of experimental hydrometorological data has shown that its phase state is subdivided into three subsets. Each of these subsets is particular to its thermodynamic characteristics and should be considered as an individual climatic scenario. The basic result of the study was obtained by estimation of evolution of the phase trajectory of parameters of thermodynamic conditions of the Northern Atlantic climate system that directly influences a vast area of the Eurasia continent. The three climate scenarios were attributed to periods of 1905–1935 (relatively warm phase), 1940–1970 (cool phase), and 1980–2000 (warm phase). According to our analysis and some independent indications 1], we believe that, in the first decade of the current century in the Northern Atlantic, a transition to a new (relatively cool?) climate scenario began, which appears likely to continue until 2030–2035.
