Short summary

We investigate the impact of model resolution on different processes in the North Atlantic using three different resolutions of the same climate model. The higher resolutions allow for the explicit simulation of smaller-scale processes. We found differences across resolutions in how denser waters are formed and transported southward, impacting the large-scale circulation of the Atlantic Ocean.
