海洋通风是示踪剂和年轻的水从表面向下转移到海洋内部。可以传输到深处的示踪剂包括人为热量和碳，这两者对于了解未来的气候轨迹至关重要。通风发生在高纬度和中纬度地区，但它是南部中纬度地区的人为热量和碳吸收的最大部分负责;这样的南大洋通风是本次审查的重点。南大洋的通风是通过一系列相互关联的机制发生的，包括纬向平均纬向翻转环流、局部俯冲、沿沿着等密度线的涡旋驱动混合以及副热带环流的横向输送。为了解开复杂的通风途径和调和相互矛盾的结果，在这里，我们评估这些机制的相对贡献，强调南大洋密度跃层的通风的三维和随时间变化的性质。我们的结论是，南大洋通风取决于多个过程，通过一个单一的过程来解释通风变化的简化框架是不够的。《海洋科学年度评论》第14卷的预计最终在线出版日期为2022年1月。请访问http://www.annualreviews.org/page/journal/pubdates了解修订后的估计数。
Ocean ventilation is the transfer of tracers and young water from the surface down into the ocean interior. The tracers that can be transported to depth include anthropogenic heat and carbon, both of which are critical to understanding future climate trajectories. Ventilation occurs in both high- and midlatitude regions, but it is the southern midlatitudes that are responsible for the largest fraction of anthropogenic heat and carbon uptake; such Southern Ocean ventilation is the focus of this review. Southern Ocean ventilation occurs through a chain of interconnected mechanisms, including the zonally averaged meridional overturning circulation, localized subduction, eddy-driven mixing along isopycnals, and lateral transport by subtropical gyres. To unravel the complex pathways of ventilation and reconcile conflicting results, here we assess the relative contribution of each of these mechanisms, emphasizing the three-dimensional and temporally varying nature of the ventilation of the Southern Ocean pycnocline. We conclude that Southern Ocean ventilation depends on multiple processes and that simplified frameworks that explain ventilation changes through a single process are insufficient. Expected final online publication date for the Annual Review of Marine Science, Volume 14 is January 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
