Thanks to its large-scale teleconnections, the Atlantic Meridional Overturning Circulation (AMOC) plays an active role in shaping the Earth’s Climate. Many studies and observations indicate that in recent years the AMOC is undergoing a declining phase. However, although this weakening is supposed to have dramatic consequences all over the globe, regional impacts are still largely unknown. With this work I contribute to improve understanding of the climatic responses of tropical Atlantic precipitation and Hadley atmospheric circulation to an AMOC slowdown. To pursue this objective, I analyze and post-process an ensemble of future projections deriving from eighteen global climate models simulations that belong to the Coupled Model Intercomparison Project 6 (CMIP6).
