This study analytically examines the possible presence of double Kelvin waves along the Okinawa Trough in the East China Sea. Not only was the response of sea level to transient and time-periodic wind forcing from the north confirmed following Mysak (1969),but also to steady-state and moving wind forcings was examined according to the realistic wind fields in the East China Sea. Double Kelvin waves generated by these forcings, due to the discontinuous depth trapping, propagate southward and disperse. Finally, these dispersive waves shift to free ones. The moored current meter observations in summer and winter of 1987 along the Okinawa Trough supported the analytic solutions. There was a southward propagating current fluctuation with a speed of 0.32 m/s along the escarpment which was documented by Lin and Guo (1990).
