一个具有高分辨率海洋分量的海气耦合模式
A COUPLED OCEAN-ATMOSPHERE MODEL WITH A HIGHER RESOLUTION OCEANIC COMPONENT
-
摘要: 发展了中国科学院大气物理研究所（IAP）大气科学与地球流体力学数值模拟国家重点实验室(LASG)全球海-陆-气耦合系统模式的一个新版本（GOALS-5），其中海洋分量是基于30层高分辨率的海洋环流模式。对该耦合模式成功地进行了30年的积分，基本上克服了气候飘移。与GOALS较早的几个版本模拟的SST相比，北半球夏季中高纬地区的误差显著改善，可能主要是由于采用了GM90的等密度混合方案使经向热输送增强的结果。对赤道中东太平洋冷暖事件有较好的模拟能力，并且对SST变率的模拟在位置和强度上比旧版本有明显改善。

Abstract: A new version of the IAP/LASG Global Ocean-Atmosphere-Land System (GOALS) model (called GOALS-5) with a higher resolution Oceanic General Circulation Model (OGCM) component is developed. GOALS-5 has been integrated successfully for 30 years without climate drift. The SST simulated by GOALS-5 in mid-and high-latitudes for the Northern Hemisphere summer is greatly improved in contrast with the results simulated by several old versions, which is maybe attributed to an enhanced meridional heat transport resulting mainly from the use of GM90 isopycnal mixing scheme. The new model version also has the ability to simulate the warm and cold events over the central and eastern equatorial Pacific. In comparison with the previous versions, the simulated amplitude and location of SST anomaly in the tropical Pacific is ameliorated in the new model -
