2012-2023年喀什地区暖季分级短时强降水时空分布特征
Spatiotemporal Distribution of Classified Short-Term Heavy Precipitation during Warm Season in Kashgar from 2012 to 2023
摘要
Abstract
Based on hourly precipitation data from 178 meteorological stations in Kashgar from April to October in 2012-2023,this study statistically analyzes the spatiotemporal distribution characteristics of short-term heavy precipitation of different magnitudes in the region.The results show that the frequency of short-term heavy precipitation in Kashgar is distributed in the pattern of north>south>east and shallow mountain areas>plain areas.The terrain is closely associated with short-term heavy precipitation.The short-term heavy precipitation mainly occurred in regions with complex terrain,such as windward slope at mountain fronts,valley,steep terrain,horn-shaped outlets,and transition zones between oasis and the Gobi desert.The interannual variation of short-term heavy precipitation is significant,with the highest frequencies occurring during 2016-2018,2017 recorded the most events(155)and 2012 the fewest(10).The annual variation of short-time heavy precipitation frequency of different magnitudes is generally consistent with the total frequency,all peaking in 2017.On monthly and ten-day scales,the frequency of short-term heavy precipitation exhibits a unimodal distribution,with the highest frequency concentrated in July-August,the cumulative frequency reached its maximum(140 times)in mid-July,while the maximum of extreme rainfall intensity appeared in early August(87.9 mm/h).The diurnal variation displays a bimodal pattern,with the highest frequency from evening to midnight,a secondary peak from midnight to early morning,and the lowest frequency from morning to noon;short-term heavy precipitation of different magnitudes occurs most frequently from 19:00 to 01:00.关键词
