中国极地研究中心自然资源部极地科学重点实验室极地气—冰—海相互作用研究团队一项对北冰洋 巴伦支海—喀拉海区域内潮动力学的研究，打破了学界对喀拉海峡附近海洋动力过程的传统认知，为深 入理解北极潮汐混合机制提供了全新视角。该研究成果近日在国际期刊发表。 巴伦支海—喀拉海区域是北极海冰变化的敏感核心区域，也是北冰洋大西洋化的前哨区域，同时还 是影响东亚乃至北半球气候变化的关键区域之一。其中，喀拉海峡不仅是该区域海冰输运与能量传递的 核心枢纽，更是北极东北航道的重要节点，具有突出的科研价值与意义。喀拉海峡由于地形复杂且潮汐 活动强盛，成为海洋内波的活跃区域。海洋内波可通过驱动海水垂向混合，调控海洋热收支平衡，进而 影响海冰变化，还能通过改变海—气热量交换过程作用于大气环流，最终对欧亚中高纬度的天气与气候 产生影响。此外，内潮分裂所激发的大振幅内孤立波，还可能对北极航道的通航环境构成潜在威胁。当 前，针对喀拉海峡内波的研究仍较为匮乏，这制约了北极航道的安全规划与运营。 该团队的研究结果显示，该海区中瓦伊加奇岛的陆坡区域是另一处重要的内潮生成源，且其能量强 度甚至超过了海峡中部区域。背景环流将内潮限制在瓦伊加奇岛陆坡外侧 ...
