  abstract = {{T}he oceanic response to volcanic eruptions over the last 1000 years is investigated with a focus on the {N}orth {A}tlantic {O}cean, using a fully coupled {AOGCM} forced by a realistic time series of volcanic eruptions, total solar irradiance ({TSI}) and atmospheric greenhouse gases concentration. {T}he model simulates little response to {TSI} variations but a strong and long-lasting thermal and dynamical oceanic adjustment to volcanic forcing, which is shown to be a function of the time period of the volcanic eruptions. {T}he thermal response consists of a fast tropical cooling due to the radiative forcing by the volcanic eruptions, followed by a penetration of this cooling in the subtropical ocean interior one to five years after the eruption, and propagation of the anomalies toward the high latitudes. {T}he oceanic circulation first adjusts rapidly to low latitude anomalous wind stress induced by the strong cooling. {T}he {A}tlantic {M}eridional {O}verturning {C}irculation ({AMOC}) shows a significant intensification 5 to 10 years after the eruptions of the period post-1400 {A}. {D}., in response to anomalous atmospheric momentum forcing, and a slight weakening in the following decade. {I}n response to the stronger eruptions occurring between 1100 and 1300, the {AMOC} shows no intensification and a stronger reduction after 10 years. {T}his study thus stresses the diversity of {AMOC} response to volcanic eruptions in climate models and discusses possible explanations.},
