ESTIMATION OFSPATIAL-TEMPORAL VARIABILITY OF EXTREMWARM SEASON AIR TEMPERATURE VALUESIN THE NORTH-EAST PART OF LITTLE CAUCASUS (IN THE TERRITORY OF AZERBAIJAN REPUBLIC)

Abstract

The estimation of spatio-temporal patterns of the distribution of the hot air temperature of the extrema in the warm season using of the north-eastern slope of the Lesser Caucasus within the Republic of Azerbaijan as a case study under the influence of global climate change has been conducted. For the first time the temporal distribution patterns of the indicators of such extreme temperature regimes of warm period, the indices of summer days and tropical nights and their trends over many years have been identified. The average number of days from the summer days from April to July increases, thereafterdecreases. The largest number of summer days was observed in plain areas in July (30,1- 30,3 days), while in mountainous areas in August (2,7-12,5 days). In general, the greatest number of summer days was observed in Ganja, the smallest - in the Gay-gel. The climatic conditions of tropical nights were observed only in the lowland areas. The number of days with tropical nights was in June 1,2-4,3 days in July 12,6-21,3 days 10,7-14,9 days in August, in September 0,7-2,8 days . In some years, the mountain stations also observed the tropical nights (in 2001 14 days).
