AN ANALYSIS OF SIGNIFICANT DAY-TO-DAY FLUCTUATIONS IN THE AIR TEMPERATURE OF THE COLD PERIOD IN THE SAKHA REPUBLIC (YAKUTIA)
Climate anomalies are signicant deviations of certain meteorological elements from the climate norm. The cause of climate anomalies is large-scale deviations from the standard conditions of atmospheric circulation. The studied part of the Republic of Sakha (Yakutia) (north-east of Russia) is located in a zone of sharply continental climate, with very cold long winters, relatively hot short summers, short off-seasons and with large annual temperature amplitudes. From November to March, the territory is under the infiuence of the Asian Anticyclone. During the cold period, the anticyclonic type of weather prevails - very low temperatures, low humidity, little or no cloud cover, weak winds or calm. The usual weather pattern is occasionally disrupted by the arrival of warm air masses. There is a signicant increase in temperature, which then just as quickly returns to the background values. The authors set the task to study the synoptic conditions for the formation of sharp inter-day temperature changes in the territory of the Republic of Sakha (Yakutia). The dates of the beginning and end of the cold period are calculated and the analysis of the repeatability of the number of cases with a signicant difference in the average daily temperature in the cold half of the year for a number of weather stations is made. The characteristic synoptic situations for days with signicant day-to-day variability of air temperature are highlighted.
