摘　　要：在LICOM模式中,分别使用2种不同的海洋内部垂直混合方案,对气候平均态全球大洋环流进行了数值模拟试验。试验结果的分析比较表明,在添加F方案之后,对全球大洋,尤其是对中高纬度海域的中层水和深层水的温盐状态的模拟有显著的改进;对北冰洋中层水的核心温度及其所在深度的模拟有较大的改进。但是在本文中对于次表层水的模拟在添加F方案后结果欠佳。In the framework of the LICOM（LASG/IAP Climate System Ocean Model）,by using two schemes of vertical mixing in the ocean respectively which is the turbulence mixing scheme and adding the inertial internal wave breaking mixing scheme put forward recently the climatic type experiments of the ocean general circulation model over the global ocean are performed.The comparison and analysis of the experiment results indicate that a notable improvement in the simulation of salinity and temperature over the global ocean is attained by using T-scheme adding F-scheme,especially in the mid-and high-latitude regions in the simulation of the Intermediate Water and Deep Water;and a great amelioration in the simulation of the Atlantic Water Core Temperature（AWCT）and its depth in the Arctic Ocean is obtained.However,a shortcoming in F-scheme is that in this paper the error of simulated salinity and temperature by using T-scheme adding F-scheme is larger than that by using T-scheme alone in the subsurface layer.
