MAIN WEATHER AND CLIMATE TRAITS IN THE NORTHERN HEMISPHERE AS OF NOVEMBER 2024
 
Air temperature
 
In the first decade of the month, abnormal heat with decade-averaged temperatures 4-10° higher than normal prevailed almost everywhere in Siberia, repeatedly setting new daily temperature maxima in the Novosibirsk, Tomsk and Kemerovo Regions in Western Siberia, and surpassing old November maxima by more than +10° in a number of locations. At the end of the decade, the heat returned to the south of Primorye, accompanied by record-breaking temperatures as well. But in the rest of Russia, the average temperatures were about normal, except for the coastal regions of the Russian North where they were 2° lower than usual, and for the north-east of the country where the anomalies reached -2…-4°.
In the second decade, Atlantic warmth came to the ETR and set new daily temperature maxima in the Non-Black Earth region. Warm weather persisted in Siberia and advanced further eastward as far as to the Sea of Okhotsk, binging new temperature highs to Trans-Baikal. This decade, the weather colder than usual was only observed on the Arctic coast, from Yamal to Chukotka: there, the decade-averaged temperature anomalies were -2…-6°.
In the third decade, unprecedented warmth covered almost all of Russia: new temperature maxima were recorded in the midland part, in the Russian North, in the Urals, in the Amur River Region and in Kolyma. The decade-averaged temperature anomalies exceeded 6-12°.

MAIN WEATHER AND CLIMATE TRAITS IN THE NORTHERN HEMISPHERE AS OF OCTOBER 2024

Air Temperature

In the first decade of October, the air temperature in most of the Russian Federation was approximately normal, with the exception of the central and southern regions of the ETR where the weather was warmer than usual by 2-4 or more degrees, and new daily temperature maxima were even recorded in some locations. But at the same time, new temperature minima were set in the south of Western Siberia and of the Krasnoyarsk Territory.

In the second decade, abnormal colds occupied almost the entire country, the weather in the south of Siberia became extremely cold, new temperature minima were recorded in the Novosibirsk Region and the Altai Territory, and the areas with the weather warmer than usual reduced to the Russian North and Kolyma where the decade-averaged temperatures were 2-3 or more degrees above normal. New temperature maxima were measured in the Arkhangelsk Region and the Republic of Karelia.

In the third decade, a significant part of Russia was invaded by the air which was abnormally warm that time, and the cold weather only prevailed in Taimyr and Evenkiya, in the central regions of the Khabarovsk Territory and partly in the North Caucasus. The northern and central regions of the ETR, the Urals, and the north and south of the Far East were now dominated by the warmth. The decade-averaged temperature anomalies reached 2-4 or more degrees, and new positive extremes of air temperature were repeatedly recorded in the Russian North, in central Russia, Western Siberia, Kamchatka and the Kuril Islands as well as on the Arctic Islands beyond the Arctic Circle.
