摘　　要：文章利用通化地区6个国家地面气象观测站建站年至2023年逐日降水资料,分析通化暴雨的时空演变特征,并运用Morlet小波分析、滑动t检验方法,对代表不同地理特征的梅河口、通化市区、集安3个观测站暴雨日数随时间变化特征作进一步分析,以期为通化暴雨的预报提供气候背景,为预报服务提供技术支撑。This article utilizes daily precipitation data from six national ground meteorological observation stations in Tonghua region until 2023,the spatial-temporal evolution characteristics of rainstorm in Tonghua are analyzed,and Morlet wavelet analysis and sliding t-test methods are used to further analyze the temporal variation characteristics of rainstorm days at Meihekou,Tonghua urban area and Ji'an observation stations representing different geographical characteristics,in order to provide climate background for rainstorm prediction and provide technical support for prediction services.
