鸭绿江口及东港近海降水与旱涝分析

Analysis of Precipitation and Drought in Yalu River Estuary and Donggang Coastal

利用中尺度地面观测资料,分析了鸭绿江及东港近海的降水与旱涝之间的关系。对大气环流的分析表明,天气系统的移动直接影响降水的产生,并导致旱涝年的形成。在分析一般规律的基础上,进一步分析了季风与旱涝的关系,以及地形对降水产生的影响。

Using the mesoscale surface observation data,the relationship between rainfall and drought in Yalu River and the coastal water of Donggang was analyzed. The analysis of atmospheric circulation indicated that the movement of weather system directly influenced precipitation and lead to formation of flood and drought years. Based on analyzing the common law,the relationship between monsoon and drought was further analyzed as well as impact of topography on precipitation.
