The key weather and climate features in the northern hemisphere in May 2016
Air temperature
In the Russian North during the whole month prevailed abnormally warm weather. The thermometers rose to 27-29°C. New record maximum temperatures have been established. As a result, the average monthly temperature anomalies were above 4°C here, and last May was the warmest in the twentieth and twenty-first centuries. Only in the distant 1897, May was also a little warmer - by 0.1°C.
To the south of the European part of Russia, the mean temperature for the month were close to normal, or even colder then it. In the Pskov and Leningrad regions, Republic of Karelia, the Upper Volga was observed freezing. The same happened in the southern Urals, but there, as well as in the Volga and Western Siberia, in the third decade came hot weather with temperatures up to 30 °C and above.
The key weather and climate features in the northern hemisphere in April 2016
Air temperature
In the European part of Russia most of the month dominated abnormally warm weather. Daily temperature highs were recorded in the west (Kaliningrad and Pskov region.), in the central region (Smolensk and Bryansk region.), in the Volga region and the Crimea. In Simferopol, the thermometer closely approached to + 30ºC. Records of maximum temperatures in the Russian North has become a habit already. In the North-West Federal District, last April was the warmest in the history of meteorological observations, and in the Crimea - the third warmest. Yet April is only the middle of the spring, so there is no wonder that the cold weather came here in the third decade. In the central, western and southern regions, the average temperature for the third decade was lower than the norm. In the south, in the Krasnodar region and the North Caucasus republics night frosts reached -3ºC. Anomalies of average monthly air temperature in the European Russia totaled over + 2-4ºC.
Much stronger they appeared in the Urals - + 4-8ºC. Here the whole month was abnormally warm. Air temperature for the month exceeded norms by 8-11ºC. April 2016 in the Urals Federal District was the third warmest since 1891.
