介绍了中国气象局自主研制的新一代全球与区域一体化数值天气预报系统（GRAPES）,着重讨论了该系统的全可压/非静力平衡动力框架，全球模式/区域模式一体化设计，半隐式-半拉格朗日差分方案，标准化、模块化、并行化、模式程序软件体系等核心技术特点。GRAPES系统已在国家级、区域级气象业务中心，以及一些大学和研究所得到应用，并在不断地完善和发展。

The global/regional assimilation and prediction system of a new generation developed by China Meteorological Administration（CMA）was introduced. The main characteristics of the system were discussed, such as full compressible and hydrostatic/non-hydrostatic approximation in option, global/regional unified model, semi implicit-semi Lagrange decretization scheme, standardization, modularization and parallelization of the model software, etc. GRAPES has been applied in national and regional meteorological centers, universities and research institutes.
