摘要：

The rising speed, periodicity, seasonal signal and low-frequency signal of sea level change in the South China Sea are analyzed with 1993-2011 seal level anomaly (SLA) data providing by AVISO, and influence factors of seasonal and low-frequency signal of sea level change in the South China Sea are discussed by combing the Ishii temperature-salt data and Southern Oscillation index (SOI) data. The results show that the sea level rising speed is 4.9mm/a. The distinct periodicity is annual period. In addition, there are 0.5a, 1.5a, 2.5a and 7a period. The low-frequency signal is influenced by ENSO. The low-frequency signals of steric sea level (SSL), SOI, SLA have some correlations and the time lag when the relativities of SSL, SLA and SOI reach the maximum are almost the same. ENSO modulates sea level change in the South China Sea through SSL
