在北太平洋西部的亚热带海域，黑潮向极地输送热量、盐分和动量，就像它在北大西洋的类似物墨西哥湾流一样。尽管黑潮通常以“附着”流的形式沿着台湾至日本东南部的西部边界流动，但黑潮的强度、垂直结构和水平位置在整个路线上经历了显着的时空变化。普遍存在的中尺度涡旋和复杂的地形与一串边缘海联合收割机相结合，使西北太平洋成为一个具有复杂环流的区域。在这里，我们综合的结果，从最近的美国起源的黑潮和棉兰老海流和台湾观测的黑潮运输变率观测计划与以前的研究结果，建立一个全面的黑潮从台湾东北部到日本东南部的路线，目前最终从西部边界电流过渡到黑潮延伸，一个积极曲折的自由射流。
In the subtropical western North Pacific Ocean, the Kuroshio delivers heat, salt, and momentum poleward, much like its North Atlantic analog, the Gulf Stream. Though the Kuroshio generally flows along the western boundary from Taiwan to southeastern Japan as an "attached" current, the Kuroshio's strength, vertical structure, and horizontal position undergo significant temporal and spatial variability along this entire route. Ubiquitous mesoscale eddies and complicated topography associated with a string of marginal seas combine to make the western North Pacific a region with complex circulation. Here, we synthesize results from the recent US Origins of the Kuroshio and Mindanao Currents and Taiwan Observations of Kuroshio Transport Variability observational programs with previous findings to build a comprehensive picture of the Kuroshio on its route from northeastern Taiwan to southeastern Japan, where the current finally transitions from a western boundary current into the Kuroshio Extension, a vigorously meandering free jet.
