摘要
由灾害天气国家重点实验室数值预报研究部开发的区域中尺度数值预报系统（GRAPES_Meso）经过国家气象中心一年多的连续实时业务试验运行，达到了项目的指标要求，系统运行稳定，预报效果较现有的区域数值预报系统（HLAFS025）有明显改进。2006年7月，GRAPES_Meso通过了由中国气象局组织的业务运行专家评审。2006年7月26日，中国气象局正式批准GRAPES_Meso投入业务运行，同时停止运行HLAFS025业务系统，
The GRAPES_Meso （Global/Regional Assimilation and PrEdiction System_Meso） developed by the State Key Laboratory of Severe Weather proved to be stable and have reached the requirements of the relevant indexes, with remarkable improvement in prediction accuracy compared with the existing numerical prediction system （HLAFS025）, through one-year real-time trial operational use at the National Meteorological Center. In July of 2006, GRAPES_Meso passed the evaluation of the expert team on operational prediction organized by the China Meteorological Administration.
