The climatological water mass features, the seasonal variabilities of the thermohaline structure, and the linkage between fluxes (momentum, heat, and moisture) of the East China and Yellow Seas have been investigated. The long term mean surface heat balance corresponds to a heat gain of 15 W/m2 in the Yellow Sea shelf (YS), a heat loss of around 30 W/m2 in the East China Sea shelf (ECS) and Cheju bifurcation zone (CB), and around 65 W/m2 in the Taiwan Warm Current region (TWC) and Kuroshio Current region (KC). The surface fresh water balance, i.e., evaporation minus precipitation, ranges from -1.8 to -4.0 cm/ month for the five subareas. The four seasons for the stud area are divided based on the relative heat storage, which do not follow the usual atmospheric seasons. The entire water column of the ECS, YS and CB undergoes a seasonal thermal cycle with maximum values of temperature during summer and maximum mixed layer depths during winter. Only the surface waters of TWC and KC exhibit a seasonal thermal cycle. Two patterns exist in the surface salinity and Yangtze River run-off, out of phase in the East China Sea and in phase in the Yellow Sea.

There exists a need in the oceanography community to be able to produce climatologies of remote or poorly sampled shallow water areas through remote sensing techniques. Our goal was to construct a three-dimensional thermal structure of the Yellow Sea based primarily upon sea surface temperature data. The ability to do this successfully could lead the way to applying these techniques elsewhere using remotely sensed SST. The shallow water and dynamic conditions of the Yellow Sea made it an ideal study area. The large MOODS observational data set for the area provided us with 15,000 observations from 1929 to 1991. For the winter months we used regression techniques on the predominantly well-mixed, vertically isothermal profiles with excellent results. For the summer we applied a Feature Model which extracted physically significant depths and gradients from the observations. These modeled data were statistically compared with mixed results indicating little link between SST and mixed-layer depth but good correlation between SST and thermocline gradient. We believe interannual variability and significant sampling errors in our data contributed to our mixed results. Overall, we feel our approach is robust and has potential for further applications providing data quality issues are addressed.

This book summarizes achievements of the study on circulation and air–sea interaction and development of the ocean observation network in the South China Sea in the last 20 years, thus serving as a comprehensive reference book to understand the dynamic environment in the SCS. It consists of seven chapters, briefly reviewing our understanding of the SCS circulation and air–sea interaction in chapter 1, then describing in detail the upper layer circulation from large scale (SCS through flow, SCS western boundary current, etc.), to meso- and submeso-scale in Chapters 2 and 5, dilute river plume and coastal upwelling over the shelf in Chapter 3, deep ocean circulation in Chapter 4, tropical cyclone activities and air–sea flux at the interface in Chapter 6, and the construction of the observation network and database in Chapter 7. Besides the basic features of these physical processes, the book also discusses their variations and fundamental dynamics. Thus, it is written in a way that meets the different information demands from researchers working in various marine related fields.
