摘要 On the basis of hydrographic data and current measurement (the mooring system, vessel-mounted ADCP and toward ADCP) data obtained in June 1999, the circulations in the southern Huang-hai Sea (HS) and northern East China Sea (ECS) are computed by using the modified inverse method.The Kuroshio flows northeastward through eastern part of the investigated region and has the main coreat Section PN, a northward flow at the easternmost part of Section PN, a weaker anti-cyclonic eddy be-tween these two northward flows, and a weak cyclonic eddy at the western part of Section PN. Theabove current structure is one type of the current structures at Section PN in ECS. The net northwardvolume transport (VT) of the Kuroshio and the offshore branch of Taiwan Warm Current (TWCOB)through Section PN is about 26.2× 106 m3/s in June 1999. The VT of the inshore branch of TaiwanWarm CArrent (TWCIB) through the investigated region is about 0.4 × 106 m3/s. The Taiwan WarmCurrent (TWC) has much effect on the currents over the continental shelf. The Huanghai Sea CoastalCurrent (HSCC) flows southeastward and enters into the northwestern part of investigated region, andflows to turn cyclonically, and then it flows northeastward, due to the influences of the Taiwan WarmCurrent and topography. There is a cyclonic eddy south of Cheju Island where the Huanghai Sea CoastalCurrent flows to turn cyclonically. It has the feature of high dense and cold water. The uniform and coldwater is occurred in the layer from about 30 m level to the bottom between Stations C306 and C311 atthe northernmost Section C3. It is a southern part of the Huanghai Sea Cold Water Mass (HSCWM). On the basis of hydrographic data and current measurement (the mooring system, vessel-mounted ADCP and toward ADCP) data obtained in June 1999, the circulations in the southern Huanghai Sea (HS) and northern East China Sea (ECS) are computed by using the modified inverse method. The Kuroshio flows northeastward through eastern part of the investigated region and has the main core at Section PN, a northward flow at the easternmost part of Section PN, a weaker anti-cyclonic eddy between these two northward flows, and a weak cyclonic eddy at the western part of Section PN. The above current structure is one type of the current structures at Section PN in ECS. The net northward volume transport (VT) of the Kuroshio and the offshore branch of Taiwan Warm Current (TWCOB) through Section PN is about 26.2 x 10(6) m(3)/s in June 1999. The VT of the inshore branch of Taiwan Warm Current (TWCIB) through the investigated region is about 0.4 x 10(6) m(3)/s.
