The reporter learnt from the Meteorology, Hydrology and Space Weather Center of the General Staff Headquarters (GSH) of the Chinese People's Liberation Army (PLA) that a new-generation numerical weather forecast system independently researched and developed by China will serve the launching and recovery of the Shenzhou IX spacecraft, which is also the first time for the new-generation numerical weather forecast system to serve a manned space flight project.

With the most advanced technology, the highest resolution and the longest period of validity among China's numerical weather forecast systems, the new-generation numerical weather forecast system has the functions of using global meteorological observation data and issuing mid-term global weather forecast. Its period of validity has increased from five days to eight days and its support capability on refinement and accuracy has also been markedly improved.

The new-generation numerical weather forecast system passed the appraisal in December 2011. Wang Yegui, head of the expert panel on Shenzhou IX spacecraft meteorological support and chief engineer of the Meteorology, Hydrology and Space Weather Center of the GSH of the PLA, held that the new system will play an important role at critical junctures such as rocket fueling, launching and recovery of the spacecraft and manned rendezvous and docking.
