Air temperature

With the beginning of July, the heat in the ETR intensified and spread as far as the Urals and the coast of the Kara Sea in the north. The anomalies of decade-averaged temperature were +2-3° in the central region, +4-5° in the south and +5-8° in the north. New daily temperature maxima were recorded in the Volga Region, in the Urals and in the Rostov, Volgograd and Lipetsk Regions. The air heated up to +40° or above in places. The decade-averaged air temperatures were close to normal in the west of the ETR only including Karelia and the Leningrad, Pskov and Novgorod Regions. The weather became colder in the second decade, and the decade-averaged air temperatures returned to their normal values over the most part of the ETR already. The anomalous heat solely survived in the south, in the Volga Region and in the Urals. Hot air fluxes from the Western Kazakhstan resulted in record-breaking temperatures in the Middle and Southern Urals where the thermometer readings rose above +40° sometimes. In Orenburg, a new absolute maximum of air temperature in July was set. The temperatures in the Sverdlovsk and Orenburg Regions and in Bashkiria remained extreme for 5-7 days in succession. There, the average air temperature in the second decade was 6-8° above the normal value. The weather grew colder in the third decade. The average air temperature in the centre and the west of the ETR was subnormal. New daily temperature minima were recorded in the Pskov, Yaroslavl, Tula, Ryazan and Tambov Regions. The anomalous warmth remained solely in the south and along the coasts of the Barents and Kara Seas. Yet, considering the overall monthly figures, the air temperatures in the South, Volga and Western Ural Federal Districts were 2-4 or more degrees above the normal values. In the rest of the ETR, they were approximately normal, and in the Leningrad, Pskov and partly Novgorod Regions, lower than that. In the Volga Region, this July was the fourth warmest in the history of meteorological observations.
The monthly-averaged air temperature in most of Siberia was close to normal. Only in the central regions of the Krasnoyarsk Territory, this value was somewhat lower than the normal one: cold weather prevailed there for most of July. The anomalies of decade-averaged air temperatures in the second and third decades reached -2° or more.


Air Temperature

With the beginning of summer, warmth finally came to the European territory of Russia. It was not clearly apparent at once: the average air temperatures in the first decade closely matched their normal values save for the south where the weather was hotter than usual and new temperature maxima were recorded in the Crimea and the Krasnodar Territory. But the second decade was marked with the ultimate victory of warmth. The anomalies of decade-averaged air temperatures in the ETR exceeded +3…5°. New heat extremes were being recorded not only in the Southern Federal District now, but also in the North-Western one, in Saint-Petersburg for example. In the third decade, such excess heat survived in the western part of the ETR only, while the decade-averaged air temperatures to the east of Moscow became normal or subnormal. From time to time, colds would break through to Central Russia and the Volga Region– most vehemently, in the last days of June. In the Volga-Vyatka, Moscow, Ryazan and Vladimir Regions, the air temperature reached the lowest values ever recorded on those days by the morning. In the Volga Region, this June concluded with a negative air temperature anomaly.
In the Urals and in West Siberia, the weather surprised with the abnormal heat of May lasting for the whole first decade. Then, the air temperature returned to normal first, and later dropped as the Arctic colds came to this region in the third decade. The anomalies of decade-averaged temperature were -5…-7° or below.
In Eastern Siberia and in the Far East, heat prevailed in the north, and cold, in the south. All June was very warm along the Arctic Coast (with the anomalies of the decade-averaged temperatures reaching +5…10° or more). In contrast, the weather in the south of the Far East remained cold for the whole month (the anomalies being -2…-4° or lower), with the same anomalies observed in the south of Eastern Siberia in the first decade.
