Natural zones and climate
The common characteristic features of Koryakiya’s climate are:
• Long cold winters, short and cool summers, still shorter springs and autumns;
• General sub-zero average annual air temperature;
• Shallow uneven snow cover in the open spaces of plain and mountain tundras;
• Strong all-the-year-round winds;
• General spread of permafrost (total or sporadic).
The investigations of the temperature regime in Koryaksky reserve has not been performed, but we have data obtained by the meteorological station of the village of Tilichiki in 2015. The distribution of temperatures in the area of the meteorological station is of continental character, which is confirmed by low temperatures in winter and relatively high temperatures in summer (absolute maximum 22,3 ℃, July 30, 2015; absolute minimum -28,1 ℃, December 12, 2015). However, the nearness of the Bering Sea has a significant influence on the climate of the region. The average duration of frostless period in the continental part is 90-95 days, on the coast it is 130-145 days. An intensive wind regime is characteristic of the territory. In winter winds of the north and north-west bearings prevail, with the average speed of 7-10 meters per second, and in summer – south-eastern ones with the average speed up to 6 meters per second. Windless periods are very rare (2% of time). The peculiarities of the snow cover are influenced mostly by its redistribution by winds and rather frequent thaws during winter.
