摘要 本文应用复经验正交函数分析方法对1899—1980年期间北太平洋夏季海平面气压距平场进行分析。第一主分量表明,北太平洋海平面气压场是以副热带太平洋高压存在和位移为主要特征,其空间波动的传播方向有较大的差异。另外二个主分量则分别与我国多雨和少雨的型式相配合。此外,本文还探讨了北太平洋夏季海平面气压场与黄河、长江流域各分区旱涝的关系。

Abstract:The Complex Emperical Orthogonal Function (CEOF) technipue was applied to the data, which are 96-point summer sea-level pressures on the Northern Pacific from 1899 through 1980 A.D.The dominant feature of the first principle Component in this area might be the existence and displacement of quasi-permanent atmospheric active centre, the Tropical Pacific High, The moving direction of spatial wave in low latitude was different from that in high latitude. The second aad third components could correspond to the flood and drought patterns in China, respectively.The relationship between the sea-level pressure field and drought/flood over the Huanghe and changjiang valleys has been also discussed it this paper. Based on multi-spectral analysis, the coupling oscillation with two-three years appeared between the pressure field and drought/flood variation. Meanwhile, it was pointed out that the oscillation seemed to represent a major feature by synchronous teleconnection. In addition, there were other relativities between them.
