一个较高分辨率的基于通量订正的海-气耦合环流模式的设计和性能评估

Design of a coupled ocean-atmosphere general circulation model with high resolution based on flux anomaly coupling scheme and its assessment

采用日通量距平耦合方案,将中科院大气所最新发展的两个具有较高分辨率的大气和海洋环流模式耦合,并进行了10年以上的耦合积分。为了评估模式的基本性能,对比分析了耦合与未耦合的大气环流模式和海洋环流模式模拟结果,结果显示耦合模式比较成功地控制了"气候漂移",可以较好地模拟平均气候态和季节变化。

Using daily flux anomaly coupling scheme, a coupled ocean-atmosphere general circulation model （GCM） with high resolution is developed. After integrating more than 10 years with this coupled model, the sim- ulation results are analyzed and compared. The results show that the coupled ocean-atmosphere GCM can con- trol the ＂climate drift＂ successfully and reproduce the mean climate state and seasonal variations well.
