摘要

摘要: 在以前提出的惯性内波破碎(细结构)的理论谱模型的基础上, 该模型中计入了水平科氏频率分量对等位密度面的作用, 在大洋环流模型(OGCM)中在低于表面混合层的稳定分层的海洋内部垂直混合的一个参数化方案在本文中被初步提出. 除了湍流之外, 亚中尺度海洋过程(包括惯性内波破碎产物)对海洋内部混合的作用被强调. 我们建议在OGCM中添加本文中提出的惯性内波破碎混合方案(简称为F-方案)到Canuto等于2010年提出的湍流混合方案(简称为T-方案)中, 除去从15°S 到 15°N的区域. 使用WOA09资料和一个 OGCM (LICOM, LASG/IAP Climate System Ocean Model)对于全球大洋使用F-方案的数值结果在本文中给出. 使用T-方案添加F-方案, 对于全球大洋盐度和温度的模拟获得了显著的改进, 尤其在中纬度和高纬度海域对于中层水和深层水的模拟. 我们推测, 惯性内波破碎混合和风场的惯性强迫是维持抽风过程的重要机理之一. 对于大西洋经向返转环流(AMOC)强度的模拟, 使用T方案添加F方案的结果比仅使用T方案更为合理, 尽管物理过程需要进一步研究, 而且溢出流参数化需要加入环流模型中. F方案的缺陷在本文中为在次表层使用T方案添加F方案模拟盐度和温度的结果比仅使用T方案的误差加大.

Abstract: Based on the theoretical spectral model of inertial internal wave breaking (fine structure) proposed previously, in which the effects of the horizontal Coriolis frequency component f-tilde on a potential isopycnal are taken into account, a parameterization scheme of vertical mixing in the stably stratified interior below the surface mixed layer in the ocean general circulation model (OGCM) is put forward preliminarily in this paper. Besides turbulence, the impact of sub-mesoscale oceanic processes (including inertial internal wave breaking product) on oceanic interior mixing is emphasized. We suggest that adding the inertial internal wave breaking mixing scheme (F-scheme for short) put forward in this paper to the turbulence mixing scheme of Canuto et al. (T-scheme for short) in the OGCM, except the region from 15°S to 15°N. The numerical results of F-scheme by using WOA09 data and an OGCM (LICOM, LASG/IAP climate system ocean model) over the global ocean are given. 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. We conjecture that the inertial internal wave breaking mixing and inertial forcing of wind might be one of important mechanisms maintaining the ventilation process. The modeling strength of the Atlantic meridional overturning circulation (AMOC) by using T-scheme adding F-scheme may be more reasonable than that by using T-scheme alone, though the physical processes need to be further studied, and the overflow parameterization needs to be incorporated. 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.
