About this book

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.

Frontmatter
Chapter 1. Overview of the Atmosphere and Hydrological Environment of the South China Sea
Abstract
The South China Sea is located in tropical and subtropical low latitudes (0~23°N, 99°~121°E) with an area of about 3.5 million km2, surrounded by mainland China, Taiwan, Philippine, Malaysia Island and Indo-China Peninsula. It is the largest open sea in China, about three times the total area of the Yellow Sea, Bohai Sea and East China Sea.

Chapter 2. The Characteristics of Large-Scale Circulation Dynamics in the South China Sea
Abstract
The Luzon Strait is the only deep-water channel connecting the South China Sea and the Pacific Ocean. The characteristics of water exchange in this area have been studied by many scholars.

Chapter 3. The Northern Shelf and Slope Currents of the South China Sea
Abstract
Cyclonic circulation exists in the northern part of the South China Sea all year round (Su, Cont Shelf Res 24:1745–1760, 2004), the continental slope current is the northern flank of the cyclonic circulation in the northern South China Sea, located on the continental slope outside Dongsha Islands—Hainan Island—Jinsha Bay, with a depth of 200–1000 m.

Chapter 4. Middle and Deep Waters Mass and Circulation in the South China Sea
Abstract
The South China Sea is the largest semi-enclosed marginal sea in the Western Pacific. As a relatively isolated sea area, it has its own independent water mass system. According to the typical characteristics of temperature, salinity, density, etc., using TS diagrams, statistical indicators and other analysis methods, the South China Sea water mass can be divided into four typical water masses in the vertical direction: ① the surface waters (SW) of the South China Sea are located at 0–50 m, which potential density is less than 23.5 kg/m3, and it has the characteristics of high temperature and low salt; ② the subsurface waters (SSW) of the South China Sea are located at 50–300 m and have a potential density of 23.5–25.5 kg/m3.

Chapter 5. Mesoscale Eddy and Mesoscale Process in the South China Sea
Abstract
The first mesoscale eddy mentioned by scholars in the South China Sea is the cold eddy off the central part of Vietnam in summer (Huang et al. in Adv Earth Sci 7:1–9, 1992). Xu et al. (An overview of the horizontal circulation in the South China Sea. Science Press, Beijing, 1982) gave the climatical (seasonal average) results of the South China Sea such as the winter cyclonic eddy in the northwest of the Luzon Island and the summer anticyclonic eddy off southeastern Vietnam.

Chapter 6. Air-Sea Interaction in the South China Sea
Abstract
Sea surface temperature (SST) is an important indicator of thermal state of the upper ocean, an important factor in the air-sea coupled system, and a sensitive index of climate change.

Chapter 7. South China Sea Observation and Data Assimilation
Abstract
Before the 1980s, oceanic observation data in the SCS were very scarce and mostly concentrated in the continental shelf area. When ( Xu XZ, Qiu Z, Chen HC, et al (1982) Overview of horizontal circulation in the SCS // Editorial Department of Oceanology and Limnology. In: Proceedings of the symposium of the hydrometeorology society of the chinese society of oceanology and limnology. Beijing: Science Press: 127-L45. (In Chinese)) studied the upper and middle circulation of the SCS, they only obtained temperature and salinity data at more than 6000 stations from the Japan Oceanographic Data Center (as of 1970, SCS data from the Cooperatice Study of the Kuroshio and Adjacent current (CSK), which include Taiwan and Hong Kong to attend), and the distribution is very uneven. For example, the data in the deep water area of the central SCS and the waters of the Nansha Islands are very few.
