# China's Fengqing AI ensemble weather forecast goes operational

Full title: China Meteorological Administration puts the Fengqing AI global ensemble forecast system (V1.0) into operation

Pandaily reported on Oct 17, 2026 that the China Meteorological Administration has put Fengqing Ensemble V1.0, an AI global ensemble weather forecast system, into operation after it passed operational review at the National Meteorological Centre, with an 11-day effective forecast range for global 500 hPa height in independent tests. It extends CMA's deterministic Fengqing 1.0 model (operational since Sept 2024) to probabilistic forecasts, following ECMWF's operational AI ensemble.

## 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.

## What is disputed or not yet verified

- Verification: Operational review at the National Meteorological Centre (as reported); no paper found
