THE MAIN WEATHER AND CLIMATE FEATURES OF THE NORTHERN HEMISPHERE IN FEBRUARY 2018
Air Temperature.
February weather in Russia was intricate. It would seem that the closer to the spring, the warmer the weather should be. But everything has happened vice versa. In the first half of the month the air temperature in the most part of the country exceeded the norm noticeably. Over the first decade the average decade air temperature anomalies from west border to East Siberia have set +2…10°. New warmth records were registered in Krasnodar district and Crimea, in Russian North, Kamchatka, Chukotka and all Russian Arctic. In the middle of the month the abnormal warmth was kept only in the south of ETR and to the east of Urals. In the third decade all Russian territory, except north-east, Arctic territories and part of North Caucasus republics was captured by abnormally cold air. Temperature norms in the third decade became lower than real values by 4-10°. Record colds were registered in European territory, it was lower than -30°. The single country region with exceptionally warm weather during all month was north-east (Kamchatka, Chukotka, Kolyma). Here in all decades the average monthly air temperature exceeded the norm by 6-12° and more.
As a result, the average monthly air temperature of February in the north of Far East federal district is the second highest on the record. It succeeds only to the February 1934, i.e. the year which became the part of the period of the first instrumentally fixed Arctic warming. In other Russian regions the change of the warmth and cold caused the proximity of the average monthly air temperature to the norm. It was slightly colder the norm in the most part of ETR and in the south of Far East, warmer – to the east of Urals, where the Arctic coast, as before, showed the warmth records.
THE MAIN WEATHER AND CLIMATE FEATURES OF THE NORTHERN HEMISPHERE IN JANUARY 2018
Air Temperature.
Surprising temperature swing was observed in the Russian Federation in the last January. In the first decade almost entire country territory, except the south of Siberia and Kamchatka was in the conditions of the abnormally warm weather. In the European territory (ETR) and in the north Urals the average decade temperature norms were exceeded by 6-13°. In the north-west and centre of ETR the new temperature maximums were registered.
The abnormal temperature background was kept here in the second decade, although it became weaker (decade anomalies - +4…9°). In Polar area the warmth records were achieved. But at the same time the cold air captured entire territory of the country from Urals to the Pacific ocean, as well as in Volga area and North Caucasus. In Yakutia the frosts reached -60°, in Siberia they impended closely to -50°, in Volga area - -30°. But, in some areas in the south of Siberia (Kemerovo region, Altai district) in the middle of the summer it was warmer than 0°.
