| 摘 要： | 本文采用区域高分辨率海洋数值模型，将谱松弛动力降尺度方法应用于吕宋海峡及其邻近区域，对吕宋海峡黑潮流径的流型特征进行模拟与分析。实验结果显示，应用谱松弛法能够较好地改善区域模型的模拟效果：通过约束大尺度误差，不仅能直接约束区域内的大尺度海洋状态，也间接调整了小尺度过程的演变规律，改善了吕宋海峡黑潮流径的模拟效果。

| Abstract: | The spectral nudging dynamic downscaling method is applied to a high-resolution ocean model covers the Luzon Strait and its adjacent areas, in order to improve the Kuroshio current simulation. The results show that, by restraining the large-scale bias, not only the large-scale of the ocean state can be constraint well, but also the small-scale phenomenon and its evolution are improved significantly. |
