Sitting at a corner stone of the global thermohaline circulation, the Agulhas Current system, comprising of various components, is of relevance for global and regional climate on all timescales. Work undertaken in this area over the last few years have highlighted that this region is sensitive to changes owing to global climate change. In particular, an increase in the amount of Indian Ocean waters entering the Atlantic has been noted as a result to wind pattern changes in the Southern Hemisphere. This intrusion of additional heat and salt into the Atlantic could potentially impact on the stability of the meridional overturning circulation and the heat transport into the North Atlantic. Based on the success of the original AGULHAS proposal that led to substantial and genuine new views of the dynamics of this regime, we propose a continuation and extension of the model integrations to further elucidate the role of the Agulhas Current system in the global climate system. This proposal is connected to the BMBF funded project SPACES.
