About the Edition

The circulation in the South China Sea (SCS) is mainly determined by the monsoons. This monsoon-induced circulation is connected with the circulation in the Pacific Ocean to a small extent and linked with that of the Indian Ocean only by the Timor Current. During winter, the water enters the South China Sea at the north through Formosa Strait and Luzon Strait, and exits at the south through Karimata Strait. During summer, the circulation reverses, the water enters at the south and exits at the north. Water from the north is generally cooler than water from the south. The northward (southward) flow induces warm (cold) advection. Therefore, the seasonal cycle of the circulation in the South China Sea becomes a major factor controlling the seasonal cycle of the sea surface temperature, which might effect the seasonal variation of the Eastern Asian monsoon system. In the preliminary results, the seasonal circulation and temperature patterns simulated by the primitive equation model are similar to those reported by Wyrtki(1961). Yet, our model is better than the Pohlmann (1987) shallow-water model and shows more details

  Advances in understanding the upper ocean circulation of the South China Sea (SCS) since the works of Dale () and Wyrtki () are reviewed. and numerical simulation .   A three-dimensional Regional Ocean Modeling System is used to study the seasonal water circulations and transports of the Southern South China Sea. The simulated seasonal water circulations and estimated transports show consistency with observations, e.g., satellite altimeter data set and re-analysis data of the Simple Ocean Data Assimilation. South China Sea upwelling system presents some unique features compared with the other upwelling systems in the region: 1) It is a seasonal coastal upwelling drive by southwesterly monsoon wind, 2) The upwelling water process affected by the circulation in the Gulf of Thailand. The trend of South China Sea upwelling was observed using Regional Ocean Modelling System (ROMS) simulation ( The South China Sea (SCS) is the largest tropical marginal sea and spans a region from the equator to 23°N and from 99°E to °E with an average depth over m. It connects to the Pacific Ocean through the Luzon Strait, which is a deep channel with a sill depth of about m.

The Finite Volume Community Ocean Model (FVCOM) was adapted to the Northern South China Sea (NSCS) to investigate the seasonality of coastal circulation, as well as along-shelf and cross-shelf transport.

In fall and winter, southwestward current dominates the NSCS shelf, while the current’s direction shifts to northeast in summer. The circulation pattern in spring is more Author: Yang Ding, Zhigang Yao, Lingling Zhou, Min Bao, Zhengchen Zang.

Abstract Seasonal and inter-annual variability of the mixed layer temperature in the Southern South China Sea (SSCS) is investigated using a regional ocean circulation model simulation.

Numerical experiments and the dynamical analyses show that (1) for the steady state inflow condition there is an insignificant loop current in the Bashi Strait like that in the Gulf of Mexico. This is probably due to the narrow outport and inport distance and the unfavourable.
