The weather in the Russian Federation supported the first month of spring general warming trend. Although in different regions of the country warm and cold periods during the months succeeded each other, in general in March the average temperature was almost everywhere significantly higher than the norm. In most parts of the country anomalies of mean monthly air temperature were + 3 ... + 5°C, and on the Arctic islands in the Barents Sea - + 11-12°C. Only in Chukotka, the air temperature was lower than normal.

New daily temperature highs were set in the Black Earth and the Volga region, the North Caucasus and Trans-Baikal region, Yakutia and the Far East. Already in the beginning of the month in the North Caucasus, the air warmed up to + to 25°C. At the same time, cold and freezing were still frequent. In Kolyma and Chukotka cold reached -40 ... -45°C, in the Komi Republic - -35°C, and even in the Moscow Region up to -15°C.

Anomalies of the average decade temperature reached + 12 ... 13°C. In the south end of the month air warmed up to + 20 ... to 25°C. In the North-West, Central and Urals federal districts last February was the warmest in the history of meteorological observations, i.e., since 1891, and in the Volga - it is the second among the warmest after February 2002.

The key weather and climate features in the northern hemisphere in January 2016

Air temperature

European territory of Russia was experienced with the real winter weather in the first decade of the new year. In the central and north-western regions frosts reached -25°C and below (in the Khibiny - up to -40°C). As a result, the mean decade negative temperature anomalies covered the entire territory from the western border to the Urals, reaching -10°C or lower values. In the second half of the month the weather has changed dramatically and become more like a spring (temperature anomalies for the third decade amounted to + 5°C or more). As a result, on average for January over most of European Russia have developed temperature conditions close to normal and only in the northwest it still was colder than usual for about 2-3°C.

Another cold center in the territory of Russia was located in the south of Siberia, where on average it turned out colder than normal by 2-6°C. Finally, the third is Kamchatka, where during the whole month it was colder than normal, but much less than in Siberia - by 2-4°C.

The key weather and climate features in the northern hemisphere in December 2015

Air temperature

December 2015 proved to be a very warm one in Russia. In the whole European territory, Siberia and Altai almost every day were established record values of daily maximum air temperature. In the first decade of the month the average temperature in the south of Siberia exceeded the norm by 12-16°C, not far below the anomaly have been here in the second decade and only the third - the cold air from the eastern regions of the country came over. In Central Russia in December the thermometer rose to near 10°C of heat. Only in the east, the whole month was colder than usual. Eastern regions of Yakutia, Kolyma, Chukotka and Kamchatka experienced the frost of 50°C. As a result, in general, over the last month the average temperature in the south of Siberia were higher than the norm by 8-10°C, on European territory by 4-6°C. At the same time, in the northeast of the country they fell short of standardd by about  1-2°C. In the Volga region it was the warmest December in history, and in Central Russia - the second warmest. The distribution and size of the anomalies of mean temperature for December in the territory of Russia are very similar with the December two years ago. The only difference is that in the place of the current cold weather in the northeast of the country in December 2013 there, so as in Siberia, were large positive anomalies in temperature (+ 10°C). Therefore, December 2013 is the warmest in the annals of Russia, while December 2015 only rounded out the top five warmest.

In the Far East, the heat of the first decade gave way to the cold in second and third. Especially in the Kamchatka and Chukotka, where the average decade temperature was below the norm by 4-6°C. Strong warming took place in the European territory of Russia in the last week of the month. In the Black Earth, the Middle Volga and the Lower Volga were recorded daily maximum temperatures. In the south, in the Krasnodar and Stavropol Territories, Rostov Region the thermometer rose to summer values of +20 ... 25°C. At the same time, in Yakutia, Irkutsk Region and Trans-Baikal frosts reached -45°C, which is typical for the middle of winter, but not fall. During all month, the weather was very warm in the Russian North and the Arctic islands. As a result, the average temperature in November in the Russian sector of the Arctic exceeded the norm by 4-12°C. In the fight against heat and cold in the Southern Urals and southern Siberia and Kamchatka the cold won. Here, the average temperature for the month was less than the norm by 1-3°C.
