| 英文摘要 | The characteristics of zonal anomaly and change rule of temporal distribution of annual precipitation in the northeastern china are revealed in this paper with eof (empirical orthogonal function) and reof (rotated empirical orthogonal function) methods and results are drawn in the standard relief maps with gis technology for practical application. data used in the study were obtained from 208 meteorological stations over the northeastern china from 1961 to 2001. eof results show that the first 3 loading vectors could give entire spatial anomaly structure of annual precipitation. in the northeast plain including the songneng plain and the liaohe plain, there is a regional compatibility (whether wet or dry) of annual precipitation change and this precipitation pattern has occurred since the late 1980s to the present. there also exist annual precipitation patterns of wet (or dry) in south and dry (or wet) in north and wet (or dry) in east and dry (or wet) in west. reof results display 8 principal precipitation anomaly areas by the first 8 rotated loading vectors: the west plain, the liaodong hills, the sanjiang plain, the liaoxi hills, the changbai mountains, the hulun buir plateau, the southwest plateau and the liaodong peninsula. |
