| 摘 要： | 在分析辽宁汛期降水的气候特征基础上,着重对影响辽宁汛期降水的环流特征进行了分析,结果表明:(1)近44年辽宁汛期降水呈下降趋势并出现显著的年际、年代际变化特征。(2)辽宁汛期水汽来源于西南夏季风和我国东部海域,汛期降水异常与低空的西南、东南夏季风、中空的极涡、西风槽、西太平洋副热带高压活动及高空的南亚高压关系密切。

| Abstract: | Based on the analysis of climatic characteristics of precipitation in flood season of Liaoning,the circulation characteristics infulence on precipitation in flood season Liaoning are analyzed.The rsults are as follows:(1) precipitation shows the decreasing trend and remarkable interannual and interdecadal variations in flood season in the last 44 years.(2) precipitation anomalies in flood season have a good correlations with southwest and southeast summer monsoon,polar vortex,west wind trough,the subtropical high over West Pacific and South Asia High. |
