In order to find the circulation anomaly in the South China Sea, the circulation of 19952000 had been calculated by the ECOM hydrodynamic numerical model. The elevation and circulation of January and August in 1998 indicated that there were great anomaly of elevation and circulation after this El Nio event.(1)In January, the whole South China Sea had positive sea level anomaly and anticyclonic velocity anomaly, so the cyclonic circulation was weaker than normal.(2) In August, the South China Sea had positive sea level anomaly, especially stronger in the east of Vietnam, and cyclonic velocity anomaly in south, anticyclonic velocity in north, especially strong in the east of Vietnam. So the cyclonic gyre in the north and the anticyclonic gyre in the south were both weaker than normal, and an anticyclonic gyre appeared in the east of Vietnam.
