TL;DR: In this article, a series of sensitivity tests were performed with a z-coordinate, global eddy-permitting (1/4°) ocean/sea-ice model (the ORCA-R025 model configuration developed for the DRAKKAR project) to evaluate the impact of recent state-of-the-art numerical schemes on model solutions.

TL;DR: Coordinated Ocean-ice Reference Experiments (COREs) as mentioned in this paper is a tool to explore the behaviour of global ocean-ice models under forcing from a common atmospheric dataset, which is suitable for our purposes, even though its evaluation originally focussed more on the ocean than on the sea ice.

TL;DR: Detailed modelling experiments—backed by palaeoceanographic and sustained modern observations—are required to establish firmly the role of the Agulhas system in a warming climate.

TL;DR: Simulation characteristics from eighteen global ocean-sea-ice coupled models are presented with a focus on the mean Atlantic meridional overturning circulation (AMOC) and other related fields in the North Atlantic as discussed by the authors.

TL;DR: In this paper, the authors present a review of the interocean exchange around South Africa: the estimation of the fluxes into the South Atlantic from different types of observations, their present level of understanding of the exchanges dynamics and forcing, its representation in state-of-the-art models, and, finally, the impact of the Indian-Atlantic fluxes on regional and global scale both within the Atlantic Ocean and in interaction with the overlying atmosphere.
