摘要
文章介绍了暴雨过程的定义,并利用2008—2017年汛期(4—9月)湖北省气象观测站逐小时降水量资料对暴雨过程进行了分类;同时对90个鄂西南地区暴雨过程的持续时间、过程降水量、短时强降水的频数空间分布和日变化特征以及极端强降水特征进行了详细地统计分析。分析结果以期进一步揭示鄂西南地区强降水规律性,为鄂西南地区暴雨的预报预警提供参考。
The definition of rainstorm process is introduced,and the rainstorm process is classified by using hourly precipitation data of Hubei meteorological observatory in flood season(April-September)from 2008 to 2017.At the same time,the spatial distribution and diurnal variation characteristics of frequency,process precipitation,short-term heavy rainfall and extreme heavy rainfall characteristics of 90 rainstorm processes in southwestern Hubei are statistically analyzed in detail.The analysis results are expected to further reveal the regularity of heavy rainfall in southwest Hubei,and providing reference for the forecast and early warning of rainstorm in southwest Hubei.
