利用海表漂流浮标观测和高分辨率数值模式的示踪粒子试验,研究了黑潮在台湾东北入侵东海的路径及其季节变化规律.通过分析1989~2013年的海表漂流浮标数据,发现黑潮在台湾东北的表层入侵存在两条明显的路径:一条为沿台湾岛北岸的西北向入侵,另一条为陆坡转折附近的直接入侵;前者主要在冬季出现,而后者则全年都存在.高分辨率数值模式的示踪粒子试验印证了表面漂流浮标观测的结果,同时揭示了黑潮入侵的三维结构,给出了黑潮次表层水入侵的路径、特征和可能成因.
Using the sea surface drifting buoy observation and the high resolution numerical model tracer particle test, we studied the path and seasonal variation of the Kuroshio in the northeastward invasion of the East China Sea in Taiwan.Through analyzing the sea surface drift buoy data from 1989 to 2013, we found that the black There are two clear paths of surface tide in northeastern Taiwan: one is the northwest intrusion along the north shore of Taiwan island and the other is the direct invasion near the transition of the slope; the former appears mainly in winter and the latter exists all year round. The particle tracing experiments with resolution numerical model confirmed the observation results of surface drifting buoys and revealed the three-dimensional structure of Kuroshio intrusion. The path, characteristics and possible causes of sub-surface water intrusion were given.
