  abstract = {{I}n this study, we present a {H}olocene rainfall index based on three high-resolution speleothem records from the {W}estern {M}editerranean, a region under the influence of the westerly winds belt modulated by the {N}orth {A}tlantic {O}scillation ({NAO}). {O}n centennial to millennial timescales, we show that the {N}orth {A}tlantic ice-rafting events were likely associated with negative {NAO}-like conditions during the {E}arly {H}olocene and the {L}ate {H}olocene. {H}owever, our data reveal that this is not clearly the case for the mid-{H}olocene ice-rafting events, during which we also show evidence of positive {NAO}-like patterns from other paleo-oceanographic and paleo-atmospheric data. {H}ence, contradictory mechanisms involving prolonged periods of both north and south shifts of the westerly winds belt (resembling positive and negative {NAO}-like patterns) might at least partially trigger or amplify the ice-rafting events and the slowdown of the {A}tlantic {M}eridional {O}verturning {C}irculation. {P}lain {L}anguage {S}ummary {D}uring the {H}olocene, periods of enhanced ice-rafting, associated with cooling and sea ice expansion in the {N}orth {A}tlantic high latitudes, have been recognized over distant regions. {W}hile the causes of these events are still a matter of debate, changes in the atmospheric circulation have been proposed as a potential trigger or amplifier. {H}ere, we use speleothems to establish a precisely dated record of rainfall variability in the {W}estern {M}editerranean, a highly sensitive region to the westerly winds belt modulated by the {N}orth {A}tlantic {O}scillation. {O}ur results reveal new insights about the dynamics of {NAO}-like patterns during the {H}olocene. {O}n centennial to millennial timescales, prolonged periods of both north and south shifts of the westerly winds belt might trigger or amplify the slowdown of the {A}tlantic {M}eridional {O}verturning {C}irculation and the {N}orth {A}tlantic ice-rafting. {H}owever, not all ice-rafting events are associated with either positive or negative {NAO}-like conditions.},
