| Abstract: | The statistical characteristics of intensity change in tropical cyclones within 48 hours prior to landfall,as well as their annual,monthly,and diurnal intensity variations were studied.The relationship between intensity change and intensity,life time was analyzed.Furthermore,the spatial distribution of rapid intensifying and filling TCs was obtained.Main conclusions are as follows:(1) 12 hours before landing,these typhoons experience processes from intensifying to filling.(2) On average,the intensifying(fil... |
