Fengqing Collection V1.0 is put into operation and will play a greater role in extreme weather warnings in the future.

China News Service, Beijing, October 19 (Reporter Zhang Su) Test results based on independent samples from January 2025 to August this year show that the "Fengqing Ensemble V1.0" global ensemble average forecast of 500 hPa geopotential height has an effective forecast time limit of 11.0 days, and key indicators such as member forecast continuous classification probability score (CRPS) and dispersion-error ratio performed well...

The reporter learned from an interview on the 19th that the "Fengqing" artificial intelligence global short- and medium-term collective weather forecast system V1.0 successfully passed the operational review and was put into operation. Many experts from the Institute of Atmospheric Physics of the Chinese Academy of Sciences, the Earth System Numerical Prediction Center of the China Meteorological Administration and other institutions participated in the review.

"Fengqing Collection V1.0" is a new generation of artificial intelligence (AI) ensemble forecasting system led by the National Meteorological Center and jointly developed by the Xiongan Meteorological Artificial Intelligence Innovation Institute and the National Supercomputing Internet.

According to the R&D personnel, the system relies on the 100,000-ka AI4S computing cluster at the core node of the National Supercomputing Internet to complete training and has become a business application meteorological AI ensemble forecasting model that achieves full autonomy in data, models, and computing power. Its global effective forecast timeliness reaches 11 days, and some indicators are better than the European Center for Medium-Range Weather Forecasts numerical ensemble forecast system and artificial intelligence ensemble forecast system, marking that China's AI weather forecast has reached the world's advanced level.

It is reported that "Fengqing" has been applied and effective in real-time business. In September 2024, during the actual combat test in response to Typhoon "Capricorn", "Fengqing" locked the landing path of the typhoon more than 6 days before it made landfall, grabbing a valuable window period for Guangdong, Guangxi, and Hainan to make disaster prevention decisions. In August last year, "Fengqing" predicted scattered heavy rains in North China 8.5 days in advance.

In addition, "Fengqing" is still being upgraded. Its V1.5 version has achieved new improvements in various performance indicators. It can generate global weather forecast products for the next 0 to 15 days, updated every 6 hours, and with a resolution of 25 kilometers within 3 minutes. The number of effective forecast days exceeds 10.5 days.

The R&D team stated that in the future, it will continue to promote model optimization, focusing on improving temporal and spatial resolution, deepening the application of multi-source data fusion, and further exploring the potential of data processing and pattern analysis, so that "Fengqing" can play a greater role in extreme weather warning, regional refined forecasting and other fields.
