摘要
冷涡雨是华北地区夏季出现的一种降雨形式,针对2017年6月21~24日出现的6年来最大的冷涡雨降雨过程,从降雨时程分布、空间分布、河道过水情况、对地下水位影响以及对土壤墒情影响等方面进行分析。此次降雨过对于增加河道流量、缓解旱情、提升地下水位等起到一定的作用,同时也提出如何更好地实现雨洪资源化的新课题。
Cold rain is a kind of rainfall in summer in North China. This paper analyzes the maximum cold rainstorm and rainfall process in the past six years from June 21 to 21,2017, and analyzes the distribution of rainfall, the spatial distribution. The impact of the groundwater level and the impact on soil moisture and other aspects of the analysis, the rainfall for the increase in river flow, relieve drought, improve the groundwater level played a certain role, but also reflects how to better achieve the rain resource is placed in front of us a difficult task.
