Abstract: Earth system model, which simulates behavior and variation of the climate system, plays a critical role in climate study.Atmospheric General Circulation Model（AGCM）, which simulates the general circulation of the atmosphere through numerical integration, is a key component of an earth system model.Along with the fast development of geoscience, the resolution of AGCM is getting higher and higher.Although the rapid development of high-performance computers enables AGCM to achieve higher resolution, it has not been well studied how AGCM performs on modern high-performance computers.Grid-point Atmospheric Model of IAP（Institute of Atmospheric Physics） LASG（the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics） （GAMIL） is selected as the representation of AGCM to analyze performance characteristics and build a performance model for AGCM.The performance model provides a referee for predicting the performance characteristics and improving the performance of AGCM in future.

摘要： 地球系统模式是模拟气候系统行为和变化的重要工具，在气候研究中扮演着重要的角色。大气环流模式是地球系统模式的一个重要部分。地球科学的快速发展对大气环流模式的分辨率提出越来越高的要求。高性能计算机的发展为更高分辨率大气环流模式的研究提供必要的硬件环境。但是当前并没有针对大气环流模式的高性能计算的特征和需求等方面的研究。中科院大气所（LASG）发展的格点大气环流模式（GAMIL）被选为代表，分析大气环流模式的性能特点，并且建立了性能模型。这些分析和性能模型将为预测未来大气环流模式的性能特征和提升性能提供帮助。
