摘要

摘要: 在第I部分水平分辨率提高的基础上,提高了中国科学院大气物理研究所大气科学和地球流体力学数值模拟国家重点实验室的全球海-陆-气耦合气候系统模式(GOALS/LASG)大气模式分量的垂直分辨率。为减少地形对平流层的影响,并和其它气候模式一致,建立了基于能量守恒和角动量守恒的垂直混合坐标方案,及混合坐标下的半隐式时间积分方案,并对相关的物理过程作必要的调整。尽管主要物理过程不变,但从初步结果来看,对大气垂直结构的模拟更合理;平流层风场和温度场的模拟与观测更接近;降水、海平面气压场的分布及季节变化等特征也有明显改进。

Abstract: In this part the vertical resolution of the atmospheric component of the Global Ocean-Atmosphere-Land System Model of LASG (GOALS/LASG) is increased based on the model with increased horizontal resolution in part I of this paper. In order to reduce the influences of topography on the stratosphere as the resolution increased, the energy and angular-momentum conserving hybrid vertical coordinate is established, which is also consistent with other climate models. The hybrid vertical coordinate scheme associated with the semi-implicit method is described in this part, and some related physical schemes in the model are also adjusted. Though the main physical processes remain the same, the primary simulation results show that the vertical structure of atmosphere is more reasonable compared with R42L9 in Part I, and the wind and temperature are more consistestent with the observations. The simulated precipitation and sea surface pressure are also improved obviously.
