Insufficient observations near the origin of the Kuroshio have led to incomplete understanding of the intraseasonal variability(ISV)of the *** measurements of the Kuroshio velocity were performed with an array of three profiler moorings(122.7°e,123°e,and 123.3°e)along 18°N from January 2018 to February *** ISV of the Kuroshio at 18°N was investigated based on a combination of mooring observations and global high-resolution HYbrid Coordinate Ocean Model reanalysis *** estimated time-averaged transport in the upper 350 m across the observation transect was 6.5±2.6 Sv(1.0 Sv=10^(6)m^(3)/s).Two significant ISV peaks at 50-60 and~100 d were recognized in the power spectra of the meridional velocity and *** analysis indicated that the ISV at 50-60 d was caused by westward-propagating eddies at average propagation speed of~13 cm/s and wavelength of~635 *** ISV peak at~100 d was mainly caused by northward-propagating eddies generated in the North equatorial Current *** investigation indicated that the ISV of the Kuroshio at 18°N is dominated by meridional transport,rather than by the zonal migration of the Kuroshio main *** findings provide a better understanding of the ISV of the Kuroshio east of Luzon Island.
