THE MAIN WEATHER AND CLIMATE FEATURES OF THE NORTHERN HEMISPHERE IN AUGUST 2018

Air Temperature.
The last summer month continued to please the European Russians with the warm, and sometimes hot weather. In every of three month decades the average monthly air temperature exceeded the norm by 2-4°. During the month, the temperature rose repeatedly above +30°. The new temperature maximums were registered. At the end of the month, when the sun were noticeably lower in the sky, than in the middle of the summer, and the air must have been cooler, but this did not happen. It became to heat even more, especially in the south. However, the first breath of the autumn was sensed by the Central Russia and Upper Volga inhabitants. In the middle of the second and beginning of the third decade in Volga-Vyatka region, Bashkortostan republic, Smolensk, Tula, Moscow areas the first frosts were registered.
Another situation was observed beyond the Urals. In the first decade in Siberia and Far East, the air was cooled substantially than usual. The average decade temperature in some places became by 2-4° below the norm. The daily minimums were registered from Turukhansk in the north to Novosibirsk in the south and Chukotka in the east. Then the cold retreated and all region, especially in Siberia found itself in the abnormally warm weather, which caused the exceeding of air temperature norms by 2-6° in the second and third decades. In Krasnoyarsk district and along the Arctic coast the new temperature maximums were registered.
As a result, in the most part of Russia the average August air temperature exceeded the norm. In the European territory, in the south of East Siberia, in Transbaikalia, Taimyr and the north of Yakutia – by 2-3°. It was slightly cooler in the south-east of the Ural and south-west of Siberia federal districts, also in Sakhalin, Kuril islands and Kamchatka.

THE MAIN WEATHER AND CLIMATE FEATURES OF THE NORTHERN HEMISPHERE IN JULY 2018

Air Temperature.

In July 2018 air temperature, averaged by all Russian Federation territory, is close to the norm. However, this result is achieved due to opposition of the hot and at some times, very hot weather in the European territory of the country, and the cold one in Siberia. In the second and third decades of the month, the air temperature from Arctic to the Black and Caspian seas exceeded the decade norm by 2-7°. It was repeatedly informed on the new temperature maximums in Polar circle, as well as in Low Volga area, North Caucasus and Crimea. In the north of ETR, it was above +30°, in the south - +40°. In Murmansk during the month it was fixed 8 days with the temperature higher than +30°, it has never been before. In some Polar areas, the duration of the hot weather one can qualify as a severe weather. In republics of North Caucasus, the average monthly air temperature in July came into the first three highest values on the record.
At the same time, the minimum temperature records were registered in East Siberia, that was surprising,  because during all previous month (June) the maximum temperature values were registered here, and as Hydrometcentre informed earlier, June 2018 became the hottest one in Siberian history. July in Siberia became colder than June. In the end of the month, the early frosts covered the Irkutsk area.
As a result, the July average air temperature in the European territory of the country exceeded the norm by 2-4°, in Siberia it is less the norm by 1-3°, in the Far East is close to the norm.
