  abstract = {{T}he {A}tlantic {N}i & ntilde;o, a key mode of tropical {A}tlantic variability, strongly influences precipitation over {S}outh {A}merica and {A}frica and interacts with {P}acific {E}l {N}i & ntilde;o through intricate ocean-atmosphere dynamics. {D}espite its significance, the {A}tlantic-{P}acific response to natural external forcings remains poorly understood due to the short observational record. {U}sing multi-model simulations of the past millennium, we show that {J}anuary volcanic eruptions induce a tropical out-of-phase lagged response, with long-lasting {E}l {N}i & ntilde;o-like warming in the {P}acific beginning in austral winter, followed by austral summer {N}i & ntilde;a-like cooling in the {A}tlantic. {T}hese responses are triggered independently, driven by persistent equatorial atmospheric wave activity resulting from the interplay between relative cooling over the {I}ndian {O}cean and surrounding landmasses as opposed to the warmer {P}acific. {O}ur findings underscore the role of volcanic forcing in modulating {A}tlantic {N}i & ntilde;o intrinsic dynamics, significantly modifying the associated precipitation patterns, and contributing to a more comprehensive view of tropical interbasin ocean-atmosphere interactions.},
