利用卫星高度计资料分析了热带气旋“艾碧”(Abe, 9315)、“贝姬”(Becky, 9316)、“莫拉克”(Morakot, 0309)和“茉莉”(Melor, 0319)对吕宋海峡及其附近海域黑潮流轴的影响。研究表明1)吕宋海峡附近海域黑潮流轴容易受到热带气旋的影响而发生一定的变化。2)在热带气旋的作用下, 黑潮流轴因中尺度涡的变异而变化; 当吕宋海峡东侧的暖涡西移时, 将使黑潮的流轴向西弯曲, 有利于黑潮在该处的入侵。
The impacts of tropical cyclones Abe (9315), Becky (9316), Morakot (0309) and Melor (0319) on the Kuroshio axis near the Luzon Strait are analyzed using satellite altimeter data . The results are as follows. 1) As affected by tropical cyclone, the Kuroshio axis can be easily shifted. 2) Under the influence of tropical cyclone, the Kuroshio axis changes due to the variation of mesoscale eddy. As the warm eddy in the east of the Luzon Strait moves westward, the Kuroshio axis bends to the west , which is conducive to the Kuroshio’s intrusion through the Luzon Strait.
