| 摘 要： | 本文采用二维纬向平均模式,通过模拟试验,研究西太平洋中纬度海域海温异常对环流变化以及我国东部江淮、华北平原汛期降水的影响。按季节不同把海温异常分为南冷北暖型和南暖北冷型。结果表明前期海温异常,其后3—5个月西太平洋副高位置明显变化。例如,春季南冷北暖型异常分布(20°—35°N偏冷,35°N以北偏暖)则夏季副高增强,其脊线位置偏北,长江流域夏季(7—8月)偏旱,而华北地区偏涝。反之,得到相反的结果。

| Abstract: | In this paper, the two-dimensional zonal average model is used for the stndy of the effect of the anomalous SST (sea-surface temperature) on the western Pacific Ocean in the middle latitudes upon the general circulation of the middle latitudes and the rainy season in the Changjiang River drainage areas and Northern China. The anomalous SST is classified into two types. Southern Cool-Northern Warm and Northern Cool-Southern Warm, in accadance with different seasons. The results show that there exists a time lag of three to five months in the seasonal movement of subtropical high to respond to the anomalous SST. |
