AbstractSpatiotemporal variation of the surface Kuroshio east of Taiwan Island is investigated by quantitatively analyzing 23-year (1993-2015) sea surface Absolute Dynamic Topography data. The annual mean state of the Kuroshio is shown, with a flow width 136 km and surface transport 7.75x10(4)m(2)/s. The corresponding standard deviations of these are 28 km and 2.14x10(4)m(2)/s. Results of power spectrum analysis indicate that the primary periods of Kuroshio surface transport east of Taiwan Island are 1 and 2.8 years, respectively. Spatially, the Kuroshio surface transport southeast of Taiwan Island has greater variability than that to its northeast. That transport showed strong seasonality, with a maximum 8.8x10(4)m(2)/s in summer and minimum 7.5x10 (4) m (2) /s in winter, which was mainly caused by local monsoon winds. A linear long-term upward trend of Kuroshio surface transport during 1993-2015 was found, during which the mean, southeast, and northeast of the Kuroshio east of Taiwan Island increased by 0.30x10 (4), 0.22x10 (4) and 0.36x10 (4) m (2) /s, respectively. Correlation and composite analysis show that the Philippines-Taiwan Oscillation (PTO) is important in the interannual variability of the Kuroshio. PTO-induced relative intensity of anticyclonic and cyclonic eddies is the dominant influence on the interannual variability of the Kuroshio east of Taiwan Island.
