奇异谱方法( SSA) 是一种特别适合于研究周期振荡行为的分析方法, 它是从时间序列的动力重构出发, 并与经验正交函数相联系的一种统计技术, 是EOF分解的一特殊应用。((SSA) is a kind of special singular spectrum method is suitable for the study of periodic oscillation behavior analysis method, it comes from the time series of dynamic reconfiguration, and associated with the empirical orthogonal function a statistical technique, EOF decomposition is a special application.)
