MAIN WEATHER AND CLIMATE TRAITS IN THE NORTHEN HEMISPHERE AS OF DECEMBER 2021
Air Temperature
In the first decade of December, the distribution of decade-averaged air temperature over the territory of Russia was of zonal character. The weather was abnormally cold in the north (with the anomalies down to -5…-7°), but abnormally warm in the central part and in the south (with the anomalies up to +5° in European and to +6…10° in Asian territories). The thermometer readings sometimes dropped below -30° in the Arkhangelsk, Vologda, Kirov and Kostroma Regions, below -40° in the Kostroma Region and the Republic of Komi, and below -60° in the north of Yakutia. At the same time, the record-breaking heat was observed in the Voronezh, Belgorod, Astrakhan and Tyumen Regions, in the Republics of Mari El, Crimea, Bashkiria and Udmurtia, as well as in the Trans-Baikal and Primorye Territories.

MAIN WEATHER AND CLIMATE TRAITS IN THE NORTHEN HEMISPHERE AS OF NOVEMBER 2021
Air Temperature
In the north of the ETR, cold weather changed to abnormal warmth at the beginning of November and remained warm until the middle of the month. The rest of the ETR received even more heat (resulting in the anomalies of up to +3…5°) in the first decade. Nevertheless, colds on some days did take place there: -25° frosts were already observed in the north, and cold spells were noted in the Black Earth region, in the North Caucasus and in the Crimea. In the second decade, the temperature became normal in the central region or even lower than that in the south. But in the third decade, the heat triumphed again. Positive anomalies reached 2-3°, and new daily temperature maxima were set in the midland part (Ryazan and Moscow Regions, etc.). Bitter colds came to the north of the ETR at the end of the month. In the Arctic zone, the average air temperature in the third decade was 3-5° below the normal value.
In the vast territory from the Urals to the Pacific Ocean, especially in Siberia and in the Far East, the month was warmer than usual almost everywhere apart from the extreme north-east of the country. In Yakutia, in the Trans-Baikal and Cis-Baikal Territories, in the south of the Krasnoyarsk Territory and in the Republics of Tyva and Altai, new daily temperature maxima were recorded – for several days in succession sometimes. As a rule, the decade-averaged temperatures were 5-10 or more degrees higher than normal. At the same time, the air temperature on some days already dropped as low as -40° in Yakutia or -35° in Chukotka.
