通过对北太平洋中层水模拟和分析的3种结果的比较:在稀疏网格的LICOM全球大洋环流模式中使用Canuto等的湍流混合方案(简称T方案)并添加范植松等提出的惯性内波破碎混合方案(简称F方案),在LICOM模式中使用T方案,以及WOA09资料的分析结果,证明在添加F方案的情况下,北太平洋中层水的模拟有较明显的改进。惯性内波破碎混合可能是维持通风过程的重要机制之一,惯性频率风场的强迫作用可能是海洋内部混合的外部作用源。在WOA09资料的分析结果与数值模拟结果中均显示出北太平洋中层水的明显的季节变化,这意味着除表层水和模态水之外,北太平洋中层水在气候变化中扮演了重要的角色。模拟结果分析表明,为获得北太平洋中层水模拟的进一步改进,高分辨率的海洋模式和锋面与羽流的参数化方案是必要的。
Abstract：The comparison among results simulated by performing the coarse-resolution LICOM model over the global ocean with the turbulence mixing scheme of Canuto et al.(T-scheme for short)adding the inertial internal wave breaking mixing scheme(F-scheme for short)put forward by Fan et al.recently,those simulated with T-scheme alone,and the WOA09 data,demonstrates that a notable improvement of modeling the North Pacific Intermediate Water(NPIW)has been attained by using Fscheme,which illustrates the robustness and effectiveness of F-scheme.The inertial internal wave breaking mixing may be one of important mechanisms maintaining the ventilation process,as well as inertial forcing of wind may be an external mechanical source of mixing in the ocean interior.The obvious seasonal variability of NPIW occurs in both the observations(WOA09)and the simulation results,which implies that NPIW plays an important role in climate changes besides the surface water and Mode water.Finally analysis of the simulation results indicates that to achieve further progress of modeling NPIW the high-resolution ocean model and the parameterization scheme of fronts and filaments are necessary.
