Air temperature anomalies on the vast territory to the south from Moscow exceeded 2-6° during the first month decade. Everything changed sharply in the second decade. The first large-scale freeze came. Air temperature in Chernozemye region dropped down to -4…-6°. Decade average temperature anomalies in almost all European territory, excluding North, are negative. In the centre and in the south the temperature dropped down to -2…-4°. They were almost the same up to the end of the month.

The main specific climatic features in the Northern Hemisphere in September 2016
Air temperature
In September in the European part of Russia abnormally cold weather was predominant. The average decade values of temperature in some areas were 1.5 - 2.0ºC below the norm. And, as a result, September was colder than usually in the Central, Southern and Volga Federal Districts. The situation was quite different in the Urals and east of the Ural Mountains. Two first decades were there exceptionally warm. In Evenkiya and Turukhansk Territory, in Taimyr and in Chukotka, in the Kuzbass and in the Baikal Lakeside, on Sakhalin and in Kamchatka daily air temperatures reached extremes quite a number of times. The average decade temperatures exceeded the normal by 4 - 8ºC. Only in the third decade steady cold weather established in Yakutia and Kolyma. The mean air temperature was here 2 - 3ºC lower than norm during the third decade. Nevertheless, freezing did not spoil the general impression of warm weather in the east of the country. In Siberia the last September was the warmest in the history of meteorological observations in Russia, and in the Ural Mountains region in occupies the second place.
