摘要
利用盂县18个自动雨量站点2016—2020年的降水数据资料,统计分析了盂县各站点年降水量、月降水量、暴雨发生过程次数和暴雨点个数,并根据盂县各站点单点暴雨过程的发生频次、出现单点暴雨点次数得出该县单点暴雨的时空分布规律为:盂县每年平均出现8次单点暴雨过程和13个单点暴雨点。月均出现单点暴雨过程次数从高到低的月份为7月、8月、6月、9月、10月、4月、5月,其中7—8月单点暴雨过程站全年的70%。出现单点暴雨点频次较高到低的站点为西潘、下社、上社,平均每年出现单点暴雨1次以上。
Based on the precipitation data of 18 automatic rainfall stations in Yuxian county from 2016 to 2020,the annual and monthly precipitation,rainstorm occurrence process and the number of rainstorm points of each station in Yuxian county are statistically analyzed respectively.The temporal and spatial distribution law of single point rainstorm in Yuxian county is as follows:there are 8 single point rainstorm processes and 13 single point rainstorm points in Yuxian county every year.The monthly average number of single point rainstorm process from high to low is July,August,June,September,October,April and may,of which the single point rainstorm process station from July to August accounts for 70%of the whole year.The stations with high to low frequency of single point rainstorm are Xipan,Xiashe and Shangshe,with an average of more than one single point rainstorm per year.
