"Look, in 2012, has long been cold, almost all of March and half of April. And then suddenly came the heat. May was a record warm, even hot in summer. That is, we have actually lost one season – spring, "- said Frolov.
This shows there is a persistent tendency to shift seasons: a long winter, spring is almost absent, warm, and sometimes extremely hot summer, Frolov said.
Summer of last year was the second warmest in the history of the entire 122-year period of observation, second only to 2010.
In Russia in 2012 took 6-7th warmest year for the entire period of observation. The area covered by ice in the northern polar region, in September 2012, has reached the absolute minimum on record and made 3 million 346 thousand 200 square meters. km, adds RBC.
In place of the relatively warm autumn came extremely cold December. According to Frolov, such as cold as last month, Russia has not been for 12 years. The temperature was below normal in all federal districts, with the exception of the Far East. In this case, significant abnormalities were reported in southern Siberia, Yakutia. Central Federal District in December set a record for the duration of frost.
"Absolutely, amazing, unique phenomena in the Arctic. Anomalies reach 5-7 degrees on average per year, the positive anomalies. This is a unique phenomenon never before observed" – quoted by ITAR-TASS Frolov.
One of the causes of temperature anomalies in the Arctic was warming Gulf Stream. At the same trend occurred in the north, according to a meteorologist, will continue to only grow. Another regularity in recent years scientists call shift seasons. The prolonged cold winter abruptly into a hot summer, practically skipping spring. On what will be the forthcoming summer season, the head of Hydromet promised to tell in March.
