American scientists say that global warming is not has a direct relationship to the abnormal heat, which is observed in Russia last summer, reports Associated Press.Researchers at the National Administration Oceanic and Atmospheric (NOAA) on March 9 issued a report in which Russia anomaly 2010 was named a natural climatic phenomenon.Extreme weather "caused the natural atmospheric changes," says the report, which will be published on the pages of Geophysical Research Letters.
The main reason for the anomaly meteorologists called a stable anticyclone, blocking the movement of air masses and thus not allowed to change the weather for a long period of time."No doubt, it was a rare event, but things unfortunately happen, and rarity in itself does not indicate any special reasons.", - Said one of the leaders of the research team Randall Dole.
However, scientists believe that the causes of such events should be carefully considered, because such serious climatic anomalies have a negative impact on the global
researchers said that for Russia the heat in 2010 did not record - in the 1930s.west Russia have experienced similar climatic conditions, also accompanied by drought.However, for other regions of the world the last decade has been extremely hot."Looks like we're on the cusp of that period, when the possibility of such events is growing rapidly and to a large extent, this growth is related to the concentration of greenhouse gases in the Earth's atmosphere." - Stated in the report of the research team.
note that the opinion of the American scientists contradicts statements Russian meteorologists.Exactly one month ago, the head of Roshydromet Alexander Frolov on the expanded board meeting of the agency made a sensational statement that the average temperature in Russia in the last ten years has grown twice more than in the rest of the world.
According to the director of Roshydromet, this record was recorded for our country and for the entire globe.But at the same time, if the entire planet temperature anomaly was 0.43 ° C, while in Russia it reached a value of 1,1 ° C.According to Frolov, amid rising temperature anomalies 7% increase in the number of dangerous weather phenomena.
addition to global warming, and an unfortunate weather circumstances, among the causes of the abnormal summer featured another - the most exotic.According to Professor Hydrometeorological Institute Valentin Sapunov, heat and drought could trigger the eruption of the Icelandic volcano Eyjafjallajokull, which began April 14, 2010.
Recall that in July - August 2010, in the European part of Russia established an abnormally stable anticyclone, which heated the air in the settlements, including in Moscow, to record temperatures.According to weather forecasters, none anticyclone previously held for so long.Finally, he left only at the end of August.The worst consequence of the anomaly for the capital's residents began to smoke from a wildfire surrounding the city.
As a result, established in the capital of extreme heat, sharply increased mortality in the population.According to Ministry of Health data released in 2010, in July, the number of deaths increased by 50.7% in Moscow.
Last year experts from the National Oceanic and Atmospheric Administration recognized the hottest in the history of meteorological observations.This title he shared with 2005, which was previously considered the record (the observations are from 1880).Third place is keeping 1998, when the excess of the average temperature was 0.6 ° C.
