The response of the Atlantic Ocean to North Atlantic Oscillation (NAO)‐like wind forcing was investigated using an ocean‐only general circulation model coupled to an atmospheric boundary layer model. A series of idealized experiments was performed to investigate the interannual to multi‐decadal frequency response of the ocean to a winter wind anomaly pattern. Overall, the strength of the SST response increased slightly with longer forcing periods. In the subpolar gyre, however, the model showed a broad response maximum in the decadal band (12–16 years).
