Predicting and Projecting Extreme Precipitation in Coastal Cities with High-Resolution Modeling
Abstract
On 5 August 2025, hours before the ninth convection-permitting climate modeling (CPCM) Workshop 2025 was set to begin in Hong Kong, participants were confined indoors from 0500 to 1700 LT by a historic extreme rainfall event. On this day, the Hong Kong Observatory (HKO) issued black rainstorm warnings twice, which was unprecedented. Its headquarters recorded 368.9 mm of rain, the highest August daily total since observations began in 1884. During this dramatic onset, with temperatures plunging to some of August’s lowest, the workshop theme—extreme precipitation in tropical cities under a warming climate—could not have felt more urgent.
