The probability of heavy showers has increased, Hong Kong’s storms are stronger and more unpredictable. Director of the Observatory: The research and development of weather forecasts will expand to 15 days, and the future will focus on developing AI

[Ming Pao News]Global warming has made extreme weather more frequent. The new director of the Observatory, Chen Pak-wai, said that in addition to rising temperatures, Hong Kong will also face changes in severe weather in the future. For example, the probability of heavy rainstorms will increase, which will easily lead to flooding; As the water temperature rises, the tropical cyclone may continue to intensify before approaching the coast of Guangdong, posing a greater threat, and the number of “autumn typhoons” affecting Hong Kong may also increase. However, Chen Baiwei said that the development of artificial intelligence (AI) has been relatively mature in the past one or two years. The Observatory has applied AI to support weather forecasting, which is also the focus of future development. Currently, the probability and rainfall of heavy rain in the next day can be predicted, but verification is still needed; As for the 9-day weather forecast, it can also be extended to 15 days, but the accuracy still needs to be improved before it can be released for public use.
