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

Air temperature

In November, the average temperature in Russia was close to normal. However, it changes during the month were uneven. So if in the European territory on each decade the average temperature was above normal, after a large positive anomalies of the first decade in the Urals and Siberia (up to +5 ... + 7°C), in the second decade a strong cold snap occurred (anomalies to -4 ... -10°C), while in the third - here again it was warm (anomaly up to + 4 ... + 8°C), with the exception of Trans-Baikal, which still held the abnormal cold. 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.
