中文摘要：

在过去几年期间，大多数新发达数字天气预言模型采用多尺度的技术的策略。因此，中国气象学的管理奉献给自从 2003，开发全球、地区性的多尺度的模型的新一代。为了验证 GRAPES (全球、地区性的吸收和预言系统) 的性能，为它编码的科学设计和程序为两个建模，理想化的测试的一间套房被建议了并且进行，它包括密度流动测试，三维的山波浪和跨 polar 流动测试。密度流动实验显示动态核心有能力模仿非线性的流动组织的好规模和它的短暂特征。当三维的山波浪测试证明模型能复制内部严肃波浪的水平、垂直的繁殖相当好时。跨 polar 流动测试在杆附近为 semi-Lagrangian 离开点计算和模型的 discretization 表明两个的合理性。真实盒子预报表明模型有能力在象副热带的高气压那样的夏天预言大规模天气政体，并且在中间、高的纬度捕获主要摘要的模式。

英文摘要：

During the past few years, most of the new developed numerical weather prediction models adopt the strategy of multi-scale technique. Therefore, China Meteorological Administration has devoted to developing a new generation of global and regional multi-scale model since 2003. In order to validate the performance of the GRAPES （Global and Regional Assimilation and PrEdiction System） model both for its scientific design and program coding, a suite of idealized tests has been proposed and conducted, which includes the density flow test, three-dimensional mountain wave and the cross-polar flow test. The density flow experiment indicates that the dynamic core has the ability to simulate the fine scale nonlinear flow structures and its transient features. While the three-dimensional mountain wave test shows that the model can reproduce the horizontal and vertical propagation of internal gravity waves quite well. Cross-polar flow test demonstrates the rationality of both for the semi-Lagrangian departure point calculation and the discretization of the model near the poles. The real case forecasts reveal that the model has the ability to predict the large-scale weather regimes in summer such as the subtropical high, and to capture the major synoptic patterns in the mid and high latitudes.
