太平洋入流及其与北冰洋异常变化的联系

PACIFIC INFLOW AND ITS LINKS WITH ABNORMALVARIATIONS IN THE ARCTIC OCEAN

太平洋水通过白令海峡进入北冰洋 ,对北冰洋的海冰、水团和环流产生重要影响。在过去的十几年中 ,北冰洋的海冰和海洋系统发生了前所未有的异常变化 ;与此同时 ,白令海峡太平洋入流水的流量和性质发生了改变 ,太平洋水在北冰洋中的运移路径和影响范围也有所不同 ,这些变化之间的关系有待于进一步的研究。本文综述了有关的研究进展 ,探讨了北冰洋异常变化与太平洋入流变化之间的可能联系。

The Pacific water enters the Arctic Ocean through the Bering Strait, influencing the sea ice, water masses and circulation in the Arctic Ocean. During the past decade, a series of abnormal variations occurred in the Arctic Ocean. At the same time, the volume transports and features of the Pacific inflow in the Bering Strait varied obviously and the route and influence area of the Pacific water changed greatly. The relationships between these variations are still kept unrevealed. This paper reviews the advances on the relative studies and discusses the possible links between the abnormal variations in the Arctic Ocean and the changes of the Pacific inflow.
