在中国科学院大气物理研究所气候系统海洋环流模式最新版本(LICOM2.0)基础上,将模式水平分辨率提高到均匀的1/10°,垂直分辨率增加到55层,建立了一个不含北冰洋区域的准全球涡分辨(eddy-resolving)海洋环流模式.利用再分析和观测的海表强迫将该模式积分了20年,其中最后8年使用2000~2007年QuikSCAT卫星反演的风应力和再分析热通量强迫.本文利用最后8年模式输出结果,初步评估了该模式对海洋环流的基本模拟能力.相对于低分辨率的海洋环流模式,发现涡分辨率海洋模式不仅可以更好地模拟海洋中尺度涡旋的时间和空间特征,而且还能较好地模拟出西边界流的路径和位置,特别是能够重现黑潮大弯曲现象及其年际变化.另一方面,当模式的水平和垂直分辨率提高之后,模式也能够更好地模拟赤道太平洋环流和中国近海环流的复杂结构.
Based on LICOM2.0, the latest edition of the atmospheric circulation system of the Institute of Atmospheric Physics, Chinese Academy of Sciences, the horizontal resolution of the model is increased to 1/10 ° and the vertical resolution is increased to 55 layers. A model without Arctic Ocean Regional eddy-resolving ocean circulation model that is forced to integrate for 20 years by sea-surface reanalysis and observations, of which the last 8 years use the wind stress of the QuikSCAT satellite from 2000 to 2007 and again The paper analyzes the heat flux forcing.This paper uses the output of the last 8 years model to preliminary evaluate the basic simulation ability of this model for ocean circulation.Compared with low resolution ocean circulation model, it is found that the vortex resolution ocean model can not only simulate well But also can better simulate the path and location of the western boundary flow, especially to reproduce the large Kuroshio phenomenon and its interannual variation.On the other hand, when the model After the horizontal and vertical resolution increase, the model can better simulate the complex structure of the equatorial Pacific Ocean Circulation and China’s offshore circulation.
