Pathways and variability of NADW export from the Atlantic Ocean, in two eddy-resolving models

该项目将探讨北大西洋深水(NADW)从南大西洋向印度洋出口的机制和途径。将分析两个涡旋分辨海洋环流模式，以确定NADW中深流涡旋的数量和特征，以及它们在盆地间交换中可能发挥的作用。该项目还将处理非易受伤害地区运输的年际变化及其与副热带锋面的关系(如果有的话)。结果将与大西洋子午线翻转环流(AMOC)有关。研究涉及AMOC和全球温盐环流，这两个环流是全球气候系统中的关键环节。增进对大西洋和印度洋之间深层环流联系的了解，应有助于提高气候模拟和预测的确定性。

This project will address the mechanisms and pathways of North Atlantic Deep Water (NADW) export from the South Atlantic to Indian Ocean. Two eddy-resolving ocean general circulation models will be analyzed to determine the quantity and characteristics of deep flow eddies in the NADW and the possible roles they may play in the inter-basin exchange. The project will also address interannual changes in NADW transport and its relationship to the subtropical front, if any. The results will be examined in relation to the Atlantic Meridional Overturning Circulation (AMOC).The research bears on the AMOC and global thermohaline circulation which are crucial links in the global climate system. Improved understanding of the deep circulation links between the Atlantic and Indian Oceans should translate to improved certainty in climate modeling and prediction.
