Variability in Kuroshio axis in the northeast of Taiwan Revealed by Long Range Ocean Radar

摘要：

　　Since the Kuroshio variations in the northeast of Taiwan play an important role to material cycle in the East China Sea,we investigated the Kuroshio axis variation in the northeast of Taiwan using the Long Range Ocean Radar data from 2001 to 2008.We examined the Kuroshio axis variation with the time-scale from seasonal to several days.The Kuroshio in summer is relatively stable and flows along shelf edge.On the other hand,the Kuroshio in winter sometimes intrudes into the shelf.From frequency distribution of the Kuroshio axis,it is found that there are 2 modes in winter; one located at shelf edge and the other located on the shelf.This result suggests that the Kuroshio in winter does not locate on the shelf steadily but moves shoreward with short time-scale.The movement of the Kuroshio axis related to variation in wind field.In order to see relationship between Kuroshio axis variations with wind field,we also examine the Kuroshio axis variation during typhoon passage.As previous studies suggested,it is found that the Kuroshio axis moved onto the shelf associated with typhoon passage in some cases.
