本文依据东海黑潮途经海域岛屿测站资料采用滤波、调和分析、能谱方法探讨了该海域表面海温年变化及其年际变化特征，并浅释了其物理机制。其结果表明：东海黑潮沿途海温年变化趋势十分相似，其数值特征较相邻海域变化缓慢，年周期分量占绝对优势；年际变化具有显著的３年和６～７年准周期变化，还存在１０～１１年和２０～２２年准周期趋势变化。这些准周期与某些大尺度海－气现象密切相关，在金球水文气象要素和现象的年际气候变化中具有普遍意义。文中指出了黑潮海域海温年际变化的直接原因应主要是黑潮暖流自身的变动，即它的流速流量的变化；还分析了对马暖流源地海域海温变化振动结构与黑潮海域的关联性、差异及其原因。 Based on the data from island stations of the Kuroshio in the East China Sea, this paper discusses the annual variation of surface sea temperature and interannual variability of sea surface temperature using the methods of filtering, harmonic analysis and energy spectrum, and explains its physical mechanism. The results show that the annual variation trend of SST over the East China Sea is very similar, and its numerical characteristics are slower than the adjacent sea areas, and the annual cycle components have an absolute advantage. The interannual variations have significant 3-year and 6-7-year quasi-periodic changes, There are also 10 to 11 years and 20 to 22 years of quasi-cyclical trends. These quasi-cycles are closely related to some large-scale sea-gas phenomena and have universal significance in the interannual climate change of hydrofacies and phenomena in the Golden Globes. It is pointed out that the direct reason for the interannual variation of SST in the Kuroshio area should be mainly the change of the Kuroshio current, that is, the change of its flow rate and flow rate. It is also analyzed that the variation of SST variations and the Kuroshio area The relevance, the difference and the reason.
