  abstract = {{N}aturally occurring tropical {P}acific variations at timescales of 7-70 years - tropical {P}acific decadal variability ({TPDV}) - describe basin-scale sea surface temperature ({SST}), sea-level pressure and heat content anomalies. {S}everal mechanisms are proposed to explain {TPDV}, which can originate through oceanic processes, atmospheric processes or as an {E}l {N}ino/{S}outhern {O}scillation ({ENSO}) residual. {I}n this {R}eview, we synthesize knowledge of these mechanisms, their characteristics and contribution to {TPDV}. {O}ceanic processes include off-equatorial {R}ossby waves, which mediate oceanic adjustment and contribute to variations in equatorial thermocline depth and {SST}; variations in the strength of the shallow upper-ocean overturning circulation, which exhibit a large anti-correlation with equatorial {P}acific {SST} at interannual and decadal timescales; and the propagation of salinity-compensated temperature (spiciness) anomalies from the subtropics to the equatorial thermocline. {A}tmospheric processes include midlatitude internal variability leading to tropical and subtropical wind anomalies, which result in equatorial {SST} anomalies and feedbacks that enhance persistence; and atmospheric teleconnections from {A}tlantic and {I}ndian {O}cean {SST} variability, which induce winds conducive to decadal anomalies of the opposite sign in the {P}acific. {A}lthough uncertain, the tropical adjustment through {R}ossby wave activity is likely a dominant mechanism. {A} deeper understanding of the origin and spectral characteristics of {TPDV}-related winds is a key priority.},
