| 摘 要： | 对辽宁省降水的气候特征进行了详细诊断分析,结果表明:辽宁省降水呈现不同的季节变化特征,汛期降水异常在空间分布存在明显东西向差异,汛期降水异常的空间分布在不同年代有不同的位相分布特征,四季降水量的年际、年代际变化特征明显,在周期上四季3年左右的振荡特征较为一致,而且出现不同程度的10年以上周期,夏季降水的10~12年周期。

| Abstract: | The climatic characteristics of precipitation in Liaoning province was diagnosed and analyzed. The result showed that the precipitation in Liaoning province showed seasonal variations. There were many obvious differences in flood season precipitation anomalies between eastern and western parts of Liaoning and the spatial distribution of precipitation anomalies in flood season had different phase distribution characteristics in different years. The characteristics of inter-annual variation and decadal variation were obvious for the precipitation in 4 seasons. The oscillation characteristics of 3 years in the four seasons were consistent and it showed more than 10 years periodic variation and 10-12 years periodic variation in summer to different degree. |
