摘要
Abstract
The temporal and spatial variations of Kuroshio patterns in the Luzon Strait were studied with the use of the Argos surface drifter data, as well as empirical orthogonal function (EOF) mode analysis of the satellite altimeter data and the sea surface height data resulting from a three-dimensional hydrodynamic model. Both trajectories of Argo.s surface drifting buoys and EOF mode analysis results reveal that the Kuroshio patterns in the Luzon Strait have significant seasonal variations. Kuroshio leaps across the Luzon Strait all around the year. During fall and winter, Kuroshio also loops and branches into the South China Sea (SCS) through the Luzon Strait,the loop can intrude as far as 118°E.but it seldom happens in the other two seasons when SCS water joins into the Kuroshio in reverse. Model data EOF mode analysis results also indicate that one branch of Kuroshio intrudes into SCS along the continental slope of northern SCS in winter.关键词
