Abstract :
A study was made of the spatial structure and variability of hydrophysical fields at interannual, synoptic and partly seasonal temporal scales on the basis of temperature and salinity data, observed by the Japanese R.V. “Ruofu Maru” by means of 17 winter and 12 summer sections along 130, 135, 137 and 150°E from the equator up to 30-34°N in the 0-1000 m layer. The data were used in an eddy resolving barotropic model of the South China Sea (SCS). Thermal exchanges between the sea and the atmosphere were incorporated in the model low-frequency variability (with periods of several years) of the sea surface temperature (SST). Storms were simulated with a stochastic representation of the external source. A regime with long-period SST oscillations (2.5 and 1.3 years) was obtained
