摘要

摘要: 风生近惯性内波破碎引起的跨等密度面混合在海洋内部混合中起重要作用。然而其参数化对海洋模式的模拟影响仍有待进一步认识。本文给出的是在模块化海洋模式（MOM）中海洋表面边界层以下引入一个考虑风驱动近惯性内波破碎引起的跨等密度面混合参数化方案的研究工作。模拟结果显示，该方案有效改善MOM4模拟的上层1 000 m以上的温盐偏差，特别是在北太平洋和北大西洋的通风地区。数值试验表明，风生近惯性内波破碎有可能是维持海洋通风过程的重要机制之一，它使得海洋通风区的位温变冷，盐度变淡，整层等位密面加深。维持的通风过程使得北太平洋副极地大涡的影响延伸到副热带大涡。从而模拟的北太平洋中层水源头及其副热带大涡东侧的温盐更接近观测实际。同时，模拟的北大西洋经圈翻转环流强度也更为合理。

Abstract: Diapycnal mixing due to wind-generated near-inertial internal wave breaking plays an important role in the ocean interior mixing. However, the effects of its parameterization on the simulation in oceanic model remain to be studied progressively. In this paper, a diapycnal mixing parameterization due to wind-generated near-inertial wave breaking is implemented to the Modular Ocean Model (MOM) below the ocean surface boundary layer. Simulation results show that the proposed scheme can effectively improve the upper 1 000 m temperature and salinity deviations simulated by MOM4, especially in the ventilation areas of the North Pacific Ocean and the North Atlantic Ocean. Numerical experiments show that the near-inertial wave breaking may be one of the most important mechanisms to maintain the oceanic ventilation processes. It makes temperature colder, salinity fresher and isopyncal layer depth deeper in the ventilation area. The maintenance of ventilation processes extends the impact of the subpolar gyre to the subtropical gyre in the North Pacific. Therefore, the simulated temperature and salinity in the source region of the North Pacific Intermediate Water and the eastern part of the subtropical gyre are closer to the observation. Meanwhile, the simulation of the North Atlantic Ocean overturning circulation intensity is more reasonable.
