| Abstract: | Characteristics of the synoptic time scale variability over the South China Sea (SCS) are explored based on the Tropical Rainfall Measuring Mission (TRMM) and auxiliary atmospheric data. Unlike the intraseasonal oscillations, which are significant only during the summer monsoon season (May–September), the synoptic timescale disturbances are active not only during the periods of the South China Sea Summer Monsoon (SCSSM), but also after summer monsoon retreat (October–December). The maximum synoptic time scale signals occur in September. The synoptic time scale variabilities over the SCS are strong modulated by the ENSO events, especially after the retreat of the SCSSM. The synoptic timescale signals in October–December are much stronger during the La Nina years than those in the El Nino years. Moreover, the synoptic time scale variabilities over the SCS are also related the activities of the SCSSM. The synoptic time scale signals in the monsoon onset periods and the early summer are much stronger during the strong SCSSM years than during the weak SCSSM years. |
