Spatio-temporal evolution characteristics of rainstorm in Tonghua
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.
