Editor's note
On January 10, the 2024 National Meteorological Work Conference was held in Beijing. The National Meteorological Center, the National Meteorological Information Center, the Meteorological Bureaus of Henan, Guangdong, Chongqing, Ningxia and other provinces (autonomous regions and municipalities directly under the Central Government), and the Qingdao Meteorological Bureau of Shandong Province and other units made exchange speeches. Looking back on 2023 and looking forward to 2024, what do these meteorologists have to say to you?
National Meteorological Center
Accelerate the innovative application of artificial intelligence meteorology
In 2023, the China Meteorological Administration will accelerate the deployment of artificial intelligence meteorological applications, seize the development opportunities of artificial intelligence, and the National Meteorological Center will take the initiative to seek changes and adaptations, and take the lead in building a new engine for accurate forecasting.
The application of artificial intelligence technology has significantly improved the ability of accurate forecasting. Since 2017, the National Meteorological Center has focused on weather monitoring, forecasting and early warning, product production and other business links, and has successively developed more than 50 artificial intelligence meteorological application models in 4 categories, significantly improving the level of accurate forecasting and business efficiency.

AI technologies such as short-term forecasting model (NOWCASTNET) and severe weather classification forecasting model are integrated into the short-term forecasting business system of China Meteorological Administration (SWAN 3.).0), preliminarily establish a strong convection AI product system with a large model as the "core", and realize the objective and real-time guidance of strong convection early warning signals down to towns and towns for the first timeArtificial intelligence technology is used to develop minute-level forecasts of key elements, and 1 km resolution meteorological element grid forecasts are realized for key areas such as large citiesThe artificial intelligence target detection technology based on satellite cloud images has helped the global tropical cyclone monitoring and identification accuracy to reach more than 80%. The multi-link application of AI technology has become an important booster, and the forecast accuracy rate will reach a new high in 2023, and the 24-hour heavy rainstorm forecast score will increase by 98% compared with the mainstream model, reaching a record highThe 24-hour track forecast error of the typhoon was 62 km, which was the best in historyThe forecast accuracy of thunderstorms and short-term heavy precipitation has increased by 8% and 13% respectively compared with the past three years.
The center proposes the systematic construction of the "1+N" artificial intelligence meteorological forecasting model, which injects new momentum into strengthening and promoting the modernization of meteorological science and technology capabilities. Take the lead in building an independent and controllable artificial intelligence weather forecasting basic model, and develop N professional adaptation models for heavy rain, severe convection, typhoon and other disastrous weather forecasting. Jointly with Tsinghua University, we have developed a short- and medium-term large-scale model for forecasting that integrates the constraints of atmospheric physical mechanisms, and the forecast effect has been stable beyond that of Pangu. An autonomous meteorological model trained based on the reanalysis data of China's Global Atmospheric Reanalysis 40-Year Product (CRA40) was preliminarily constructed. Completed the deployment of 5 mainstream large model services, and established a feedback mechanism for large model R&D and application.
Design a next-generation integrated weather business platform. In view of the lack of intensification, intelligence, collaboration and standardization of the business platform, a new generation of weather business integration platform with "smart brain" as the core is designed, and through the United Nations leading enterprises and some provincial meteorological bureaus, the meteorological agent with planning, memory, tools and execution is designed to improve the application ability of the domestic language model in the vertical field of meteorological business, and then promote the leapfrog development of the business platform from intelligent automatic processing, intelligent forecast assistant to digital forecaster.
