CLIMATIC FEATURES OF THE WARM PERIOD OF 2021 ON THE TERRITORY OF KHANGALASSKY DISTRICT, SAKHA REPUBLIC (YAKUTIA

Khangalassky Disctrict of the Sakha Republic (Yakutia) is located in a continental climate zone with very cold long winters, hot short summers, short spring and autumn and large annual temperature amplitudes. Climate changes in Yakutia are manifested, rst of all, in signi cantly increased winter temperatures, frequent cases of atmospheric droughts in summer, changes in the beginning of spring and autumn, changes in the amount and mode of precipitation in all seasons. Global changes in the climate system have led to the fact that the geographical position of the polar front has shifted to the north. The number of cases of southern cyclones entering the territory of Yakutia in winter has increased. In winter, cyclones bring warmer and wetter air, resulting in increased temperatures and precipitation. During the warm period, the position of spring and summer anticyclones changes. In spring and summer, anticyclonic weather can cause atmospheric droughts and, as a result, forest res. In the summer season of 2021, an acute shortage of precipitation combined with extreme temperature anomalies caused the formation of atmospheric droughts in July and August in the Far Eastern Federal District, especially in Yakutia. In the summer of 2021, an extremely large number of forest res was noted in Yakutia. The res have engulfed large areas of the taiga. The authors analyzed the average daily temperature of June-August, took into account the synoptic conditions that caused atmospheric drought. The data from the Isit weather station located at the southern tip of the Lena Pillars National Park were used for the analysis. One of the res, which covered a signi cant area and threatened the village of Kytyl-Dura, operated 40-50 km of the weather station.
