摘　　要：气象应用是高性能计算的重要领域之一,随着数值预报模式的高速发展,中国气象局目前的高性能计算机系统已无法满足模式业务发展的需求,中国气象局依托"气候变化应对决策支撑工程"重点工程项目引进新一代高性能计算机系统用以支撑"十二五"期间的天气气候数值预报模式的发展,对新引进系统的建设规模估算成为必须解决的首要问题。文中主要基于数值预报模式的发展需求,根据数值预报模式各特征参数与高性能计算资源需求之间的变化关系,提出采用推算法对高性能计算机性能需求进行推算。根据该推算方法估算未来五年内中国气象局数值预报业务发展对高性能计算资源的需求量,解决了如何将应用需求转换成高性能计算机的能力需求。Meteorological application is one of the important areas of high performance computing,with the rapid development of NWP mode,the current high-performance computing system in CMA has been unable to meet the needs. CMA is introducing new generation HPC system to support the development of NWP models in the 12th five-Year period. How to estimate the scale of the new HPC system becomes the most important issue. It is mainly based on the development plan of the NWP models,study the relationship between charac-teristic parameters of NWP models and demands for HPC resources,and then suggest the calculation method of HPC performance require-ments for meteorological applications. According to the methods,CMA has estimated the demand of HPC systems resources of the next five years and solve the key issues of the procurement of the new HPC system.
