通过对ＮＣＥＰ１°×１°周平均ＳＳＴ资料（１９８２～１９９４）进行谐波分析，发现南海ＳＳＴ年循环中基波Ｗ１和第二谐波Ｗ２是决定性的谐波；诸谐波具有准驻波特征：气候平均意义下的季节内振荡不显著。此外，还讨论了南海全区ＳＳＴ在夏季风爆发之前迅速增温的原因
By analyzing the NCEP1 ° × 1 ° weekly mean SST data (1982 ~ 1994), it is found that the fundamental wave W1 and the second harmonic wave W2 are the decisive harmonics in the SST annual cycle of the South China Sea. The harmonics have quasi-standing wave characteristics : The intra-seasonal oscillations in the climatic mean are not significant. In addition, the reasons for the rapid warming of the SST in the entire South China Sea before the onset of the summer monsoon are also discussed
