摘      要：The Princeton Ocean Model (POM) was modified and used to study the monthly mean circulation in the Yellow Sea and the East China Sea. The calculated results showed almost all major characteristics of the circulation system and their seasonal evolutions. Offshore branch and inshore branch of the Taiwan Warm Current derived from the two sides of the Taiwan Island vary significantly in different seasons. The Tsushima Warm Current is a multi-source current, and especially in winter, mid-shelf water is its main source. The Yellow Sea Warm Current (YSWC) is the strongest in winter, and a part of the YSWC water always adds into the Tushima Warm Current through the north and south sides of the Cheju Island. The calculated thermal structures showed distinct path of the YSWC in winter and the position and scope of the Yellow Sea Cold Water Mass in summer. Based on the circulation simulation, suspended matter transport was modeled numerically by adding its governing equation into the POM. Simulated results on the temporal and spatial distribution of total suspended matter concentration revealed and further proved that seasonal characteristics of suspended matter transport are: storage in summer and autumn, transport in winter and spring in the Yellow and East China Seas. Shelf circulation plays a crucial role in long-term suspended matter transport.
