中文摘要:

      一些研究认为,原观测场时间序列的第一特征向量场与时间平均场表现出强相似。经研究得出,原观测场时间序列的这两个统计场间存在本质差异。它们的相似性依赖于原观测场时间序列在相空间中的结构。时间平均场(气候场)与时间偏差(异常)场集的相对强弱在二者相似与否中起到重要作用。

英文摘要:

      Some studies holded that the firsteig envector field of the time series of or iginal observations fields usually shows a striking similarity to the time-averaged field. How ever, this paper pointed out that there are intrinsic differ ences between the two statistical fields of the time series of original observ ations fields. Their similarity depends on the structure in the phase space of the time series of original observations fields. The relative intensity of the time-averaged(climatic) field and temporal anomalies fiel dset plays an import ant role in their similarity.
