摘要: Abstract Physical processes related to polynya formation are reviewed and selected examples from both the Arctic Antarctic seas given. Polynyas categorized by dividing them into mechanically convectively forced systems, recognizing that most polynyas formed a confluence of two or more physical factors, positive feedback also impact formation. strongly regional oceanography. Those initiated mechanical forcing wind, for example, may produce large quantities ice brine. Dense water in this manner can then migrate via Ekman layers, gravity currents, eddying motions across shelf, drain deep ocean. Under scenarios global warming, climatologically retreating edge will alter size distribution polynyas. In on Peninsula, general pattern relative is likely be similar.
