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.
