Abstract: In late autumn of 2017(early October),Cangzhou was affected by the intersection of warm and wet air flow over peripheral subtropical high and cold air.The continuous rainfall process occurred in Cangzhou for four days.Based on the data,this paper analyzed the temporal and spatial distribution of the rainfall and its affection on the surface water,groundwater and soil moisture.The results show that the rainfall alleviated the draught,reduced the buried depth of groundwater,and increased the storage of lakes and river runoff.

Key words: late autumn, continuous rainfall, temporal and spatial distribution, soil moisture, surface runoff, groundwater level

摘要： 2017年深秋季节(10月上旬)受副热带高压外围暖湿气流与冷空气交汇影响,沧州市区域发生了连续4日的持续降雨过程。文中通过相关的监测资料对本次降雨的时空分布以及对地表水、地下水、土壤墒情的影响进行了系统的分析,结果表明本次持续降雨过程使得全区旱情得到了明显的缓解,地下水埋深显著减小,洼淀蓄水量和河流径流量有所增加。
