| Summary: | Climate change is one of the main today'schallenges. Over the past 130 years the world's temperature has increased approximately by 0,85 °C. In physiographic terms the West Siberian sub-boreal forest (sub-taiga) is the southernmost latitude climatebelt in the subzone of the Southern taiga of the West Siberian plain. The climate belt includes mixed light coniferous, parvifoliate, and grass layer's forests located between 54 and 56 ° N. This article examines changes in temporal characteristics (start dates, end, duration) of seasons in the period from 1936 to 2015, insub-boreal forest(sub-taiga) of the West Siberian plain, derived from the schedule of average years of average daily air temperature. The foundation of our research was comprehensive genetic method of climate study of N.N.GalakhovandN.V.Rutkovskaya. Spatio-temporal trends in the dynamics of the dates of the beginning and end of the seasons of the year in podtayge are established: 1) there is a shift in time characteristics from the first period to two subsequent ones: the dates for the beginning of the spring and summer seasons - for earlier dates, the dates of the beginning of the autumn and winter seasons - for later dates of the end of the winter and spring seasons - for earlier periods; 2) their duration of the seasons of the year changes and the ratio between them in the annual cycle; 3) domination of different seasons of the year is revealed: in Tyumen - in summer, in Tomsk - in winter; 4) sharper changes in temporal characteristics in the western part of the subtaiga of Western Siberia; 5) recorded a difference in the duration of the main seasons - more than two weeks, and winters - more than a month. Analysis of the dynamics of temporary changes in natural seasonal rhythms makes it possible to assess the changing conditions of landscape functioning, to consider the directions for their further development and organization of human economic activity. |
