| Research Abstract |
In this study, I examine how the atmospheric circulation over the Arctic influence the rapid decrease of Arctic sea-ice. The results point out that the summer atmospheric circulation is characterized by strong anticyclonic circulation over the Arctic Ocean. The anticyclonic circulation influences the decrease of summer Arctic sea-ice. The decrease in the sea-ice over the Arctic has been accelerating. In recent year, the summer anticyclonic circulation over the Arctic has contributed to accelerated decrease in sea ice over the Arctic.
