| 摘 要： | 运用距离权重反比法对重庆市气象自动观测站的雨量资料进行格点化处理,采用地球椭球体梯形面积的计算方法计算出暴雨面积,对重庆市2007—2016年的各次区域暴雨天气过程进行暴雨面积估测,计算出的暴雨面积能真实反映暴雨的影响范围,并充分证实了重庆市2014年的"9·17"区域暴雨是该年重庆市影响范围最大的暴雨。通过对暴雨面积的估测,分析重庆市近10 a的暴雨面积变化趋势,反映出其总体呈增大的趋势。

| Abstract: | By using inverse distance weighting method, the rainfall of automatic station in Chongqing was processed into gridded form. The area of rainstorm was calculated by terrestrial elliptic trapezoid method. We hereby estimated the area of regional rainstorms happened during 2007 and 2016 in Chongqing by combining the aforementioned algorithms. The result showed that the calculated rainstorm area could objectively reflect the influence radius of rainstorms, and confirmed that the rainstorm on 17thSeptember2014 is the most influential one in that year. With the evaluation of the area of rainstorm in recentS10Syears, a general rising trend was identified. |
