Abstract

This thesis investigates the connectivity and interaction of remote regions in the Atlantic Ocean based on high-resolution model experiments. Connectivity between remote regions has important implications on a range of spatial and temporal scales. It can affect global climate variability, the coherence of circulation changes on regional scales and the spreading of marine organisms.
Based on several advancements in modelling, it is demonstrated how interhemispheric connectivity contributes to changes of the Atlantic Meridional Overturning Circulation (AMOC) on climate timescales. At the same time, the effect of wind-forcing and the interaction of individual AMOC pathways with eddies on regional scales are shown to be highly important to understand AMOC variability on sub-decadal timescales, with further implications on interdisciplinary research questions.
