The storm began in Alaska and walked almost the entire territory of the Arctic Sea. Over the last 34 years the number of such storms over the North Pole, recorded in August, does not exceed eight. Unusual storm called because usually such atmospheric pressure system about 964 mbar are in the Arctic, but in the winter.
According to experts, late storms can have a huge impact on the sea ice, causing it to melt at an accelerated pace. Ice by the heat of the masses rather break into lumps that are carried by the wind in the warm latitudes, and there is melting in a matter of days. Such as storms Fit warm water from lower latitudes to the Arctic glaciers, which helps them to melt, not sliding.
Scientists suggest that there will be a storm will lead to the next minimum Arctic ice. Ten years ago the storm would not cause significant changes in the thickness and quality of the Arctic ice, because then it was much thicker and stronger. Of modern observations, we can conclude that the number of storms in an uncharacteristic season began to grow in the last decades of the 20th century, which can be explained by a warmer world.
Summer cyclonic storm in the Arctic
August 11. A rare summer storm hit the Arctic this week. Beginning on the coast of Alaska, he slowly, over several days, moved over most of the Arctic Ocean, before finally dissipate.
By itself, the storm is unusual — Space Flight Center NASA (Goddard Space Flight Center) in Greenbelt, Md., said that over the last 34 years has been about eight storms so strong in August. This meteorological event was recorded on August 6 photos using Moderate Resolution Imaging Spectroradiometer (MODIS) satellite on NASA's Aqua. Cyclone rotates in the direction of the North Pole, Greenland is seen in the lower left corner. Scientists can only guess what impact can have on nature and people like cyclonic storm.
Arctic storms like this can have a strong influence on sea ice as a result of which they start to melt quickly. But in Greenland glaciers melted. In fact, these storms tear chunks of ice and drive them in warm water, or being forced to rise from the depths of the warm waters of the Arctic Ocean. Claire Parkinson, a climatologist from NASA Goddard, suggests that the storm caused the separation of large piece of ice from the main sea ice massif. It can lead to more serious decay of the ice cover in summer than it would have been, had it not been a storm. Perhaps this will lead to new Arctic minimum.
But a few decades ago, a storm of the same strength would have a smaller impact on the sea ice, as if ice was thicker and takes up more space.
