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.

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

Air Temperature.

Only Siberian inhabitants felt a real hot summer weather on the Russia territory since the first day until the end one of June. The last June became here the hottest month on the record, i.e. since 1891. Let remind you, that the last year June was also extremely hot. This time the average monthly air temperature anomalies exceeded +8°. In some areas, the temperature reached 40°, the new temperature records were registered repeatedly.
In the other regions of the country, the warmth and cold replaced each other during the month. In the European territory and Urals the cold weather (even frosts) in the first and second decades was replaced by the heat in the third one. In the south, the temperature was higher than +40°. As a result, if in the Central region, especially in the ETR south, the heat overpowered the cold (average monthly air temperature anomalies are positive here), in the most part of Volga area and Urals the cold at the average during the month overpowered the warmth.
It was colder than usual in the south of the Far East, in the north it was cold, even frosts and warmth replaced each other, as a result, the average monthly air temperature was placed in the third line of the highest ranged values since 1891.
