Abstract

Abstract

In this paper, based on a nested high resolution reginal ocean modeling system, the relatively complete system of the circulation structure in the East China Sea is constructed. By comparing the model results with the existing estimates based on measurements, the numerical model results show agreement with the observation well. The results indicate that the water exchange in the East China Sea exhibit pronounced seasonal variations. From the view of the volume transport, the Taiwan Strait, the sections east of Taiwan and the section between Iriomote Island and Okinawa Island are the main sections flow into the East China Sea, however, the section between Okinawa Island and Amami Island, Tokara Strait, the Osumi Strait, the section east of Cheju Island, and the section between East China Sea and Yellow Sea are the main sections flow out of the East China Sea. The annual mean volume transport through these sections are 1.06×10⁶ m³/s、20.49×10⁶ m³/s、3.2×10⁶ m³/s、-0.92×10⁶ m³/s、-20.59×10⁶ m³/s、-0.30×10⁶ m³/s、-2.37×10⁶ m³/s and -0.37×10⁶ m³/s (inflow is positive). Comparison of these transports (volume, heat and salinity) indicate that these transport in the East China Sea have similar trends, the maximum flux often appeared in summer (July or August), and the minimum often appeared in winter (January or February). The calculation of volume balance indicates that from July to November that the East China Sea has a net outflow, however, from December to June it has a net inflow. The East China Sea flow into the Yellow Sea throughout the year, the annual mean value of the volume, heat and salt transport are 0.37×10⁶ m³/s,0.027×10¹⁵ W and 12.7×10⁶ kg/s respectively.
