Arctic ice in October grew at a record pace, the researchers reported

© RIA Novosti.  Alexander LiskinArctic sea ice to recover their possessions winter accelerated pace in October 2011, covering the ice up to 114.9 thousand square kilometers of open sea for each day of the month, which is 40% greater than the average growth rate of ice area from 1979 to 2000, said specialists from the National Information Center for Snow and Ice (NSIDC) USA.
The average area of ice in the Arctic in October rose to 8.41 million square kilometers, which is 330,000 more than the record minimum sea ice in the Arctic, recorded by U.S. climate satellite in 2007.
In September 2011, has been fixed annual minimum ice area for the region: September 9, the figure was 4.33 million square kilometers. This is the second lowest result in the history after 2007, when the annual minimum, made on September 16, was 4.17 million square kilometers.
The area of Arctic sea ice in October 2011, was little more than the record lows of 2007 and the second highest minimum area of ice ever recorded. Believed to climatologists, the Arctic ice cover will shrink by 6.6% in each subsequent year, if current trends continue.
"The area of ice in the Arctic has increased rapidly throughout October. Area ice (sea ice extent, a figure that uses NSIDC — Ed.) Grew at a record pace — ice was added to 114.9 thousand square kilometers a day, which is 40% more similar figures for 1979-2000 years ", — said the press service of the NSIDC.
Reason for the reduction of the ice cover has once again made an abnormally high summer temperatures in the northern regions of Siberia and North America. According to experts NSIDC, average temperature in October in Siberia and the mainland of Canada and the United States exceeded the typical values for the October 5-8 degrees Celsius.
Overall, the average air temperature over the Arctic Ocean were above normal by 1-4 degrees Celsius.
On the other hand, the summer in the eastern part of the Canadian Arctic Archipelago and Greenland dawned unusually cold — the average temperature on these land areas were below normal by 3 degrees Celsius.
According to the calculations of climate scientists, the main "engine" of this anomaly is the positive phase of the Arctic Oscillation — periodically increase or decrease the low and high atmospheric pressure in the Arctic and mid-latitudes. Positive phase of the phenomenon characterized by an increase of average temperatures in the continental regions of the Arctic, and the negative — an abnormally cold winter in these regions.
Beaufort and Chukchi Sea froze only partially due to this warming, and warm water in the open areas continues to "warm up" the Arctic.
Weather conditions in the last month of 2011 were less extreme in terms of the melting ice as compared to "record" 2007. Four years ago, the air temperature in the area of the Beaufort Sea and the Chukchi Sea was five degrees Celsius above normal, while this year it was close to her. In addition, there were less significant surface temperature anomalies in the Arctic Ocean.
Experts stress that the ice in the Arctic continues to "younger" in March 2011 to the ice age of about one to two years accounted for 80% of the total area of ice cover, while in 1980-2000, the figure was an average of 55%.
