The key weather and climate features in the northern hemisphere in June 2015


Air temperature

June was abnormally warm in most parts of the Russian Federation. Only on Sakhalin Island, in the north of Primorye and the south of Kamchatka, partly in Kaliningrad, Pskov, Arkhangelsk Region and the Republic of Karelia mean monthly air temperature was a little lower than normal. In the rest of the country, it has exceeded the norm. In the Urals, western Siberia and the Lower Volga - by 4-6ºC. New temperature maxima during the month were many times recorded throughout the territory. On certain days in the Republic of Kalmykia, the Astrakhan Region and the eastern areas of the Volgograd and Saratov Regions the thermometer rose to the level of +40ºC and above. Also there was frost during the month, sometimes it comes up to new daily temperature minima. Thus, in the first decade of the month frosts happened in the north of the European territory, in Bashkiria, in the south of the Krasnoyarsk Territory, the Irkutsk region and the Trans-Baikal region, in the second decade - in the central region of Russia, and in the third decade - again on Sakhalin and in Trans-Baikal. Still the warm weather in June significantly prevailed over the cold the mean month temperature received the second rank among the highest values for this indicator yielded only by June 2012; the first half of the year was the warmest in the history of regular meteorological observations in the country.
