| 摘 要： | The Singular Spectrum Analysis (SSA) method is used to conduct studies of periodicity of theSST and meridional winds in tropical Pacific Ocean. The results show that the air-sea system for the Pacificvaries on quasi-4-year, quasi-2-year and interannual scales, with the quasi-4-year scale having the highestvariability. Depending on the scale, the wind field has a varying degree of association with the SST anomalies.Difference is also found in the evolution of phase. In addition, the work discusses the difference in SSTA resultedfrom wind fields for quasi-4-year and quasi-2-year components.
