英文摘要	Based on the geoinformation analysis, the main climatic markers (parameters and indices) of the geocryological boundaries of the cryolithozone in the European northeast of Russia have been determined. Calculations of climatic data are based on the analysis of the WorldClim database with high spatial resolution and of regional permafrost map. The analysis of climatic characteristics, stipulating the geographical differentiation of regional permafrost conditions was carried out for the background period (1960-1990). To assess the efficiency of climatic markers of permafrost boundaries, it is proposed to use the values of their variation coefficients. The decrease in the variation coefficients from north to south emphasizes the efficiency “strengthening” of climate markers towards the southern permafrost limit. To improve the efficiency of individual climatic markers of permafrost boundaries, a subdivision of the region into two sectors has been proposed. The multiple regression equation, combining air frost number (air frost index), annual amplitude of air temperature and July precipitation, explains the geographic position of regional permafrost boundaries by 83 %. © 2019 Academic Publishing House Geo.
