The Arctic Ocean is the mass of water positioned approximately above latitude 65° N. Arctic Sea Ice refers to the area of the Arctic Ocean covered by ice. The Arctic sea ice minimum is the day in a given year when Arctic sea ice reaches its smallest extent, occurring at the end of the summer melting season, normally during September.
As the Arctic continues receiving energy from the sun during this time, the land, which is mostly free of snow by now, can warm up on clear days when the wind is not coming from the cold ocean. Over the Arctic Ocean the snow cover on the sea ice disappears and ponds of melt water start to form on the sea ice, further reducing the amount of ...
The Arctic's indigenous people have a long relationship with its icy conditions, and face the loss of their cultural heritage. Further, there are numerous implications which go beyond the Arctic region. Sea ice loss not only enhances warming in the Arctic but also adds to global temperature increase through the ice-albedo feedback.
Indeed, if we observe only the month of September, the ice floe has diminished by 10.7% every ten years, compared to only 2.8% in March. Projection models of the evolution of the arctic ice floe are based on the last 30 years. These projections mainly use circulation models of ocean and atmospheric currents, such as NEMO, the OGCM and the CMIP.
The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [1] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans.
Cold air will stick around for much of the East as the calendar flips to December and could last through the first week of the new month, according to forecasts from the Climate Prediction Center.
Feedbacks associated with sea ice and snow cover are widely cited as one of the principal causes of terrestrial polar amplification. [12] [13] [14] These feedbacks are particularly noted in local polar amplification, [15] although recent work has shown that the lapse rate feedback is likely equally important to the ice-albedo feedback for Arctic amplification.
