摘　　要：随着精细化预报业务不断发展,迫切需要建立支撑国省网格预报实时同步、协同一致的全国精细化格点预报业务数据环境。本文分析了精细化预报业务的特点,阐述了基于全国综合气象信息共享平台(CIMISS)的精细化格点业务数据环境的系统架构、数据流程、核心功能及相关技术实现。业务运行结果表明,数据环境实现了国省间格点预报实时同步和共享,有效支撑了预报产品的及时订正和发布,保证了国省格点预报一致性。With the continuous development of refined forecast,we urgently need to construct the data environment to support the nationwide refined forecast system,which implements the function of real-time synchronization and concurrent gridded weather prediction between national and provincial levels.This paper analyzes the features of refined forecast and introduces the system architecture,data flow,core functions and technological realization of the data environment,which is based on the China Integrated Meteorological Information Sharing System（CIMISS）and designed to support the refined forecast system.Via the operational application it can be concluded that the data environment successfully completes the target of real-time synchronization and sharing of the gridded weather prediction products between national and provincial levels,provides sufficient capacity to support the correction and publication of the products,and ensures the productsconsistency.Finally,this paper looks into the advancement of the data environment to support the nationwide refined forecast system in the future.
