报告摘要:

The typhoons and the associated rainstorms in 2023 create big challenges to the weather forecasting and warning services. The movements of typhoons Saola and Koinu are not captured well by the conventional numerical weather prediction models. The heavy rain associated with Haikui and Koinu also results in historical rainfall records in Hong Kong.  However, the expectations from the public and the special users in Hong Kong for weather forecasting and warning services become much higher than before. This talk will briefly summarize the challenges of the forecasting services for these three typhoon cases in Hong Kong in 2023. In particular, the use of AI and a regional model appears to have potential to enhance the warning services, but their application values are still to be tested for more typhoon cases.
