"In 30 years of observing what we have on the satellite data, we increase the ice cover in the Southern Ocean surrounding Antarctica, more than 4%," — said the scientist. At the same time, the number of floating ice at the North Pole has been steadily declining, and in 2007-2008 was recorded historic low Arctic sea ice on record. At this time at the South Pole to the contrary processes.
Klepikov noted that the increase in the amount of ice was uneven in different areas of the Antarctic coast, and the most significant increase in ice area was observed in the Ross Sea in the western part of the Pacific sector of Antarctica. At the same time, in the Bellingshausen Sea opposite trend: reduction of the ice cover.
British researchers said Klepikova, with the help of mathematical models and analysis of meteorological data showed that the growth trend of ice may be linked to the so-called ozone anomaly in the South Pole. Reducing the concentration of ozone over the South Pole leads to a cooling of the upper atmosphere and, ultimately, to strengthen circumpolar vortex — winds blowing along the coast of Antarctica. The winds of the protected zone of Antarctica from the effects of the environment, warmer, air. This mechanism, according Klepikova, explains, in particular, abnormally rapid destruction of the Larsen Ice Shelf: Efforts winds were able to overcome the ridge on the Antarctic Peninsula, and as a result brought the warm air to this glacier.
