Authorities harness AI to improve weather warning systems

The government is enhancing its response to extreme weather events through four key strategies, as revealed during the eighth regular meeting of the Central District Community Service Consultative Council.

Officials highlighted a cross-departmental approach, with greater use of artificial intelligence (AI) to improve weather forecasting and public communication.

The Meteorological and Geophysical Bureau representatives noted that global warming has led to increased tropical cyclones, heavy rainfall, and high temperatures in recent years.

Since 2015, five No.10 typhoon signals have been issued. Record-breaking rainfall occurred in June 2021, while annual average temperatures continue to rise.

In response, the bureau plans to optimize its monitoring network by adding more observation sites and introducing AI and scientific research collaboration to strengthen forecasting.

Alerts will now follow a two-step system: qualitative assessment followed by quantitative detail. Information will be disseminated earlier through expanded channels, including display screens at Zhuhai-Macau border checkpoints.

Authorities also aim to improve regional coordination.
Regular joint discussions with meteorological services from mainland China, Hong Kong, and Guangdong will enhance major weather analysis. A video-conference system will support timely cross-departmental communication during typhoons.

According to the officials, the public will also benefit from enhanced outreach, with educational campaigns and visualized updates on social media and new platforms. In 2024 alone, nearly 8,800 people participated in science outreach programs.

Additional suggestions included setting up a typhoon shelter in the Central District, developing voice-enabled wearable warning devices for the visually impaired, and releasing wind data for the Macau Bridge to assess possible safe use during storms. Times Reporter
