【摘要】 过去十几年北极的快速变化以海冰变化为主要特征。然而,在冰-海-气变化系统中海洋起着关键性的作用。海洋是北极变化的关键因素,不仅影响着海冰的融化与冻结等过程,而且是大气变化的主要能量来源。在北极海冰快速变化的背景下,北冰洋的海洋特征也发生了一系列的变化。第四次国际极地年之后我国在北极科学研究中取得了一系列的进展,本文从北冰洋水团、锋面、海流等主要水文现象,以及上层海洋结构等方面,总结了2011-2014年我国在北极物理海洋学方面取得的一系列成果。更多还原

【Abstract】 Over the past ten years sea ice changes have been the main feature in the Arctic rapidly changing.However,the ocean plays a key role in the ice-sea-air change system.The Arctic Ocean not only affects the ice melting and freezing processes,but also is the main source of energy of the atmospheric change.In the context of rapid changes in Arctic sea ice,the Arctic Ocean feature has also undergone a series of changes.After the Fourth International Polar Year,Chinese has made a series of scientific research in the Arctic physical oceanography.In this paper Arctic water masses,fronts,currents,the structure of the upper ocean and other major hydrological phenomena were summed up during the 2011-2014.更多还原
