Combining theory, idealized models, and a regional ocean circulation model, we offer two complementary and dynamically consistent interpretations linking this tilt of MDT to the alongshore current and also to the area-integrated nearshore circulation. (4/5)

This includes an alongshore tilt of MDT associated with the Nova Scotia Current that is balanced primarily by wind stress, bottom friction, and a small contribution from lateral mixing. (3/5)

MDT (the local height of sea level above the geoid) can be estimated by coastal tide gauge observations in combination with the latest generation of geoid models. These new geodetic estimates can be used to validate MDT predictions by regional high-resolution ocean models. (2/5)

The model also predicts that the atmospheric circulation in response to the MJO leads to anomalous upwelling on the Scotian Shelf. (5/5)

The observed relationship between the MJO and North Atlantic SST can be captured by a regional ocean circulation model demonstrating their feasibility and potential for S2S ocean prediction. (4/5)

These changes are driven primarily by anomalous air-sea heat fluxes caused by large-scale atmospheric perturbations linked to the MJO. (3/5)

Statistically significant large-scale #SST changes in the North #Atlantic, particularly along the eastern seaboard of North America, can be related to the MJO. (2/5)
