In this article, I use the Estimating the Circulation and Climate of the Ocean version 4 (ECCO4) reanalysis to estimate the residual meridional overturning circulation, zonally averaged, over the separate Atlantic and Indo-Pacific sectors. The abyssal component of this estimate differs quantitatively from previously published estimates that use comparable observations, indicating that this component is still undersampled. I also review recent conceptual models of the oceanic meridional overturning circulation and of the mid-depth and abyssal stratification. These theories show that dynamics in the Antarctic circumpolar region are essential in determining the deep and abyssal stratification. In addition, they show that a mid-depth cell consistent with observational estimates is powered by the wind stress in the Antarctic circumpolar region, while the abyssal cell relies on interior diapycnal mixing, which is bottom intensified.

全球颠覆循环。

在本文中,我使用“估计海洋环流和气候版本4(ECCO4)”的重新分析来估计分别在大西洋和印度洋和太平洋两个区域上的子午翻转环流,按区域平均。该估计的深层成分与以前发表的使用可比较观察结果的估计在数量上有所不同,这表明该成分仍处于欠采样状态。我还将回顾海洋经向翻转环流以及中深度和深渊分层的最新概念模型。这些理论表明,南极绕极地区的动力学对于确定深层和深层分层至关重要。此外,他们表明,与观测估计值一致的中深度单元是由南极绕极地区的风应力驱动的,
