Overshooting tops are a proxy for deep convection in clouds. Using Himawari-8 satellite images, overshooting tops were identified in 45 typhoons and their diurnal variation was analyzed by Sun et al. . Strong typhoons and typhoons going through rapid intensification (RI) have a greater density of overshooting tops, than weaker typhoons, as well as those intensifying slowly or weakening. Furthermore, RI typhoons have a greater diurnal variation in overshooting top density than non-rapid intensifying typhoons. The results point to overshooting top density as a potential indicator for estimating changes in typhoon intensity and could potentially be used in the improvement of both diagnosis and prediction of typhoon intensity in the future.
