Key facts
- Pandaily (Oct 17, 2026; only the article summary was readable for us): ‘Fengqing Ensemble V1.0 passed operational review at the National Meteorological Centre, with an 11-day effective forecast range for global 500 hPa height in independent tests’
- Background (People’s Daily via Tsinghua University news, 2024): deterministic Fengqing 1.0 went operational on Sept 10, 2024, producing nine global products for 0–15 days, every 6 hours, at 25 km resolution
- Not verified: ensemble size, resolution, developers and comparisons with ECMWF’s ensemble; we have not found the CMA’s own announcement
What happened
China’s national weather service added an AI ensemble system to its operational forecasts. Our only source for the new system is a Pandaily summary (the article body loads by script and could not be read), so confidence is medium.
Why it matters
Ensembles give forecasters probabilities, not just one answer. After ECMWF, China’s CMA is now running AI ensembles operationally, which makes AI weather models a standard part of national forecasting.
