Dynamics, variability and change in Southern Ocean abyssal flows.

南大洋深海环流的变化与剧烈的气候事件有关，但人们对相关的动态了解甚少。该项目旨在确定驱动深海水流的基本动力过程，并分析近期和预测的气候变化的影响。该项目还旨在弥合对海洋翻转环流这一重要分支的概念和观测理解之间的巨大差距。一项重大创新是，这将是第一次使用能够模拟所有关键动态过程的现实全球规模模型对南大洋深渊进行研究。研究结果将指导南大洋观测计划，解释观测到的变化，并减少气候预测的不确定性。

Changes in the Southern Ocean abyssal circulation are linked with dramatic climate events, yet the associated dynamics are poorly understood. This project aims to determine the fundamental dynamic processes driving abyssal flows, and diagnose impacts of recent and projected climate change. The project also aims to bridge the large gap between conceptual and observational understanding of this vital limb of the ocean's overturning circulation. A significant innovation is that it will be the first study of the Southern Ocean abyss using realistic global-scale models capable of simulating all the key dynamic processes. Results will guide Southern Ocean observation programs, explain observed changes, and reduce uncertainties in climate projections.
