| 摘 要： | 本文基于长时间序列的海流和温盐资料（最新版SODA高分辩率再分析资料和137°E断面的观测资料），计算了黑潮流系四个主要断面的流量，并分析了它们的变化特征．结果表明，黑潮流系各主要断面流量具有显著的季节性差异，其年际、年代际变化明显．相关分析表明，源地黑潮及其上下游流量变化具有较强的独立性，变化不尽一致，其中，短期气候变化特征可能与热带太平洋的年际变化有明显关联，而年代际变化则可能与发生于北太平洋的年代际变化以及其它副热带中尺度涡旋等变化有一定联系．

| Abstract: | Based on the long series of current velocity data from the new version of SODA reanalysis, and data of temperature and salinity on 137°E section, the transport on 4 main sections of the source and adjacent areas of Kuroshio were calculated. And the annual cycle and long-term variations were analyzed. The results indicate that the transport of the main Kuroshio sections have strong seasonal and striking inter-annual and inter-decadal variations. The correlation analysis shows that there were strong independences among the variations of the transport in main sections of Kuroshio. Among them the short climate changes are likely related to the tropical Pacific inter-annuM variation, while the inter-decadal variation could be possibly associated with the North Pacific inter-decadal variations and subtropical meso-scale eddy. |
