| 摘 要： | 采用ＳＳＡ方法分析我国东南地区地面气温场，发现明显存在周期为３５─４０天的季节内低频振荡。计算还表明，ＳＳＡ不仅能有效识别振荡分量，同样也是一种很好的时间滤波方法。

| Abstract: | The Singular Spectrum Analysis (SSA) method is applied to the surface temperature field of southern China, in which a major low-frequency oscillation with period of 3 5 - 4 0 days is found . Calculation also identifies that SSA could not only recognize the oscillation component , but also an adaptive time filter. |
