摘　　要：利用AVISO数据集的卫星高度计资料,分析了中国台湾以东中尺度涡的时空特征,通过具体的中尺度涡实例探讨了其对台湾以东黑潮路径的影响。研究表明气旋式中尺度涡在春夏季节的数目要少于反气旋式中尺度涡,在秋冬季节气旋式涡旋个数则多于反气旋涡;并且台东以东区域涡旋传播存在多种路径,涡旋的存在对台湾东北部黑潮入侵东海的路径具有重大影响,特别是2004年夏季台湾以东区域存在多个涡旋,相应的吕宋海峡黑潮主轴向东偏移明显,台湾东北黑潮入侵东海的路径发生了显著变化。In this study,the characteristics of mesoscale eddies in the east of Taiwan are studied with the AVISOdatasets of satellite altimeter data.The impact of the Kuroshio intrusion induced by mesoscale eddies with four examples has been discussed.The conclusions are summarized as follows:(1)the number of cyclonic eddies is smaller than that of anticyclonic eddies in the spring and summer and larger in autumn and winter;(2)when the anticyclonic eddies are transported to the scope of the Kuroshio,the path of the Kuroshio will weaken and its velocity of will increase;(3)when the cyclonic eddies are transported to the scope of the Kuroshio,the Kuroshio intrusion will enhance and the velocity of the Kuroshio will decrease;(4)if there are more than one eddies transported to the scope of the Kuroshio,the path of the Kuroshio will be significantly changed.
