Overview of studies on some eddies in the China'seas and their adjacent seas Ⅰ.The South China Sea and the region east of Taiwan

Over view of studies on some cyclonic and anti cyclonic eddies is made in the South China Sea and the region east of Taiwan.Meso-scale eddies(MSE)are rather active in the South China Sea(SCS).Some MSE in the central and southern SCSs and the northern SCS are reviewed,respectively.The most interested problem awaiting solution in the northern SCS is as follows.How the deuce is the physical processes about water exchange between the western Philippine Sea(WPS)and the SCS across the Luzon Strait? Could the Kuroshio form a loop current west of the Luzon Strait inside the SCS when the Kuro shio intrudes into the SCS?Up to now the problem remains untouched,especially the studies about their dynamic mechanism.For solving above problems,it is very necessary to get the long-term observed currents and hydrographic data and the longterm sa ellite remote data from the cooperative program in the Luzon Strait in the future.In the region east of Taiwan,the MSE always occur in the both sides of Kuroshio,and their variability is large and complex.The following two cyclonic cold eddies are discussed mainly:the Lanyu cold eddy and the cyclonic cold eddy northeast of Taiwan.
