Abstract

Abstract

Based on the CTD data dur ing July of 1997 from the cruise of China-Japan Cooperative Study on the Subtropical Circulation and the data of the same period of Global Temperature Salinity Profile Program(GTSPP) Realtime Data Sets,the MOM2 model is used to calculate the circulation for the region of 21.875°~35.125°N, 120.875°~137.125°E.Both diagnostic and robust diagnostic simulations are done.The result of diagnostic simulations is more reliable.The main feature of the circulation pattern in this season is as below:(1)The Kuroshio east of Taiwan Island does not split into two branches as usual.(2)The volume transport(VT)of Kuroshio in the East China Sea is about 30×10⁶ m³/s.The VT south of Japan is about 70×10⁶ m³/s.(3)There is a westward flow at 21.875~25 N coming from 137°E.It splits into three br anches south of Okinawa Islands,the main branch flows northeastward east of Ryūkyū-guntö.(4)The Ryūkyū Current comes mainly from the above westward flow.
