| 使用1958－1987年COADS资料对南海全区表层水温做了分析。结果发现，南海表层水温存在20－40个月的低频振荡，其中以准两年周期最显著，，其次是3－4年．这种振荡主要发生在深水海盆区，并且与季风异常有着十分密切的关系。 |

| Abstract: |
| Analyses of the basic features of the South China Sea’s interannual low frequency SST oscillations by using the 1958 - 1987 COADS data set, empirical orthogonal function, spectrum, digital filter, etc. show that:
1) There are SST low frequency oscillations of 20 - 40 months, the most remarkable being the quasi-biennial oscillations, then those with the 3 - 4 year period.
2) These oscillations /generate in the deep water basin and are quite different from seasonal variances .
3) There is almost no propagation of SST oscillation, which implies a fast SST adjustment forced by wind anomalies.
4) The SST oscillations are closely related to the V-component of the wind anomalies. |
