The water characteristics of the East China Sea depend on influxes from river run-off, the Kuroshio, and the TWN Strait. A three-year observation using an acoustic Doppler current profiler (ADCP) operated on a ferry provides the first nearly continuous data set concerning the seasonal flow pattern and the volume transport from the TWN Strait to the East China Sea. The observed volume transport shows strong seasonality and linkage to the along-strait wind stress. An empirical regression formula between the volume transport and wind was derived to fill the gaps of observation so as to obtain a continuous data set. Based on this unique data set, the three-year mean of monthly volume transport is northeastward throughout the year, large (nearly 3. Sv) in summer and low (nearly zero) in winter. The China Coastal Current flows southward in winter, while the northward-flowing TWN Strait Current may reverse direction during severe northeasterly winds in the winter or under typhoons. The sea level difference across TWN Strait is closely correlated to the transport through the strait, and their relation is found seasonally nearly stable.
