| Abstract: | Highlights: What are the main findings? During the sudden turn of Super Typhoon Vongfong (2014), the precipitation structure also changed accordingly: the precipitation coverage expanded, convective rainfall weakened, and stratiform rainfall intensified. The intensification of stratiform precipitation was associated with enhanced warm-rain processes due to increased cloud liquid water, whereas the weakening of convective precipitation was related to weakened ice-phase processes due to decreased cloud ice content. What are the implications of the main findings? This study analyzes the evolution of precipitation during the base observation of the sudden turn of the typhoon, which can provide valuable guidance for improving flood-risk assessment, optimizing urban drainage, and emergency response planning. The findings provided observational constraints to improve the representation of cloud microphysics parameterization in typhoon prediction models and also contributed to the development of more accurate precipitation nowcasting and typhoon intensity–structure prediction tools. The sudden turn of tropical cyclones (TCs) can rapidly alter the affected disaster-prone regions and associated rainfall distributions, posing severe threats to coastal areas and creating major challenges for operational forecasting. However, most of these events occur over the open ocean, where the scarcity of in situ observations limits our understanding of how precipitation and cloud microphysical processes evolve during the sudden turning. In this study, we analyzed the precipitation evolution and associated microphysical characteristics during the sudden turn of Super Typhoon Vongfong (2014) using the latest GPM satellite observations. The main findings are as follows: (1) During the sudden-turning period, the precipitation coverage expanded significantly. Strong convective precipitation was distributed from the inner eyewall to the outer eyewall and spiral rainbands and weakened in intensity, whereas stratiform precipitation broadened in coverage and intensified. (2) The increase in stratiform precipitation was attributed primarily to increased cloud water content, which strengthened collision–coalescence processes, promoted the formation of larger and more numerous raindrops, and consequently increased precipitation efficiency and intensity. (3) The weakening of convective precipitation was related to the reduction in eyewall updrafts, which suppressed ice-phase processes and limited the development of deep convection.
