Optimal estimation of absolute geostrophic velocity field in vicinity of the Luzon Strait using variational data assimilation technique
Lan Jian, Wang Dongxiao
2002, (2): 157-163.
Abstract:
A P-vector method is optimized using the variational data assimilation technique(VDAT).The absolute geostrophic velocity fields in the vicinity of the Luzon Strait (LS) are calculated,the spatial structures and seasonal variations of the absolute geo...
Multi-scale variability of subsurface temperature in the South China Sea
Gao Rongzhen, Zhou Faxiu, Wang Dongxiao
2002, (2): 165-173.
Abstract:
Using Morlet wavelet transform and harmonic analysis the multiscale variability of subsurface temperature in the South China Sea is studied by analyzing one-year (from April 1998 to April 1999) ATLAS mooring data.By wavelet transform,annual and semi-...
Evidence for water exchange between the South China Sea and the Pacific Ocean through the Luzon Strait
Qu Tangdong
2002, (2): 175-185.
Abstract:
An analysis of historical oxygen data provides evidence on the water exchange between the South China Sea (SCS) and the Pacific Ocean (PO).In the vicinity of the Luzon Strait (LS),the dissolved oxygen concentration of sea water is found to be lower o...
A numerical study of the South China Sea deep circulation and its relation to the Luzon Strait transport
Yuan Dongliang
2002, (2): 187-202.
Abstract:
A fine-resolution MOM code is used to study the South China Sea basin-scale circulation and its relation to the mass transport through the Luzon Strait.The modal domain includes the South China Sea,part of the East China Sea,and part of the Philippin...
Structure of a pair of anticyclonic vortices in northern part of the South China Sea in autumn of 1994
Fu Gang, Toshio Yamagata
2002, (2): 203-216.
Abstract:
A pair of remarkable meso-scale anticyclonic vortices,one formed closely to another,in the northern part of the South China Sea during the period from the later August to early September of 1994 were documented by the in situ observation data.Their s...
A possible role of the South China Sea in ENSO cycle
Wang Qi, Liu Qinyu, Hu Ruijin, Xie Qiang
2002, (2): 217-226.
Abstract:
A data-based hypothesis on the role of the South China Sea (SCS) in ENSO cycle is proposed:during El Niño,there are westerly wind anomaly over the western equatorial Pacific and positive SST anomaly in the eastern equatorial Pacific.Meanwhile anomalo...
The South China Sea thermohaline structure and circulation
Peter C. Chu, Binbing Ma, Yuchun Chen
2002, (2): 227-261.
Abstract:
In this study,we used the Navy's Master Oceanographic Observation Data Set (MOODS),consisting of 116 019 temperature and 9 617 salinity profiles,during 1968~1984 to investigate the temporal and spatial variabilities of South China Sea thermohaline st...
Environmental monitoring of the Zhujiang Estuary and its coastal waters
J. C. Chen, L. Dong, L. A. Wong, G. W. Heinke
2002, (2): 275-304.
Abstract:
The Zhujiang (Pearl River) Estuary is a complex water system whose catchments basin coveers a very large part of southern China.The large quantity of fresh water carried by the river system flows into the northern coast of the South China Sea through...
Features of eddy kinetic energy and variations of upper circulation in the South China Sea
He Zhigang, Wang Dongxiao, Hu Jianyu
2002, (2): 305-314.
Abstract:
The features of eddy kinetic energy (EKE) and the variations of upper circulation in the South China Sea (SCS) are discussed in this paper using geostrophic currents estimated from Maps of Sea Level Anomalies of the TOPEX/Poseidon altimetry data.A hi...

Comparison among four kinds of data of sea surface wind stress in the South China Sea
Xie Qiang, Wang Weiqiang, Mao Qingwen
2002, (2): 263-273.
Abstract:
By using remote sensing (ERS) data,FSU data,COADS data and Hellerman & Rosenstein objective analysis data to analyze the sea surface wind stress in the South China Sea,it is found that the remote sensing data have higher resolution and more reaso...
