The Role of Atlantic Basin Geometry in Meridional Overturning Circulation

Climatology data for manuscript: "The Role of Atlantic Basin Geometry in Meridional Overturning Circulation"

We present idealized simulations to explore how the shape of eastern and western continental boundaries along the Atlantic influence the Atlantic Meridional Overturning Circulation (AMOC). We use a state-of-the art ocean—sea-ice model (MOM6 and SIS2) with idealized, zonally-symmetric surface forcing and a range of idealized continental configurations with a large, Pacific-like basin and a small, Atlantic-like basin. We perform simulations with five coastline geometries along the Atlantic-like basin that range from coastlines that are straight to coastlines shaped like the coasts of the American and African continents.
