Numerical modeling study for driving processes of the thermohaline circulation in the polar oceans

我们开发了一些物理过程的模拟方法，这通常被忽略在以前的模拟研究，与深水形成在极地海洋。通过应用这些方法，我们估算了这些物理过程对海洋温盐环流的影响。潮汐的存在通过影响海冰的分布，显著地促进了南极大陆架稠密水的形成。潮汐还以不对称的方式输送浓水，从而促进浓水向大陆坡的输出，冰架与海洋之间的相互作用减少了从南极洲周围开始的温盐环流。在气候变暖的情况下，冰架融化的增加加速了温盐环流的减弱。

We developed modeling methods for some physical processes, which had usually ignored in previous modeling studies, associated with deep water formation in the polar oceans. By applying the developed methods, we estimated the influence of those physical processes on the oceanic thermohaline circulation.The existence of tides significantly enhance dense water formation on the Antarctic continental shelves through their influences on sea ice distribution. Tides also enhance the export of dense water onto the continental slopes as they transport dense water in an asymmetric way.Interaction between ice shelf and ocean reduces the thermohaline circulation starting around Antarctica. Under a warming climate, enhanced melt of ice shelf accelerates the weakening of the thermohaline circulation.
