  abstract = {{S}ynoptic wind events in the equatorial {P}acific strongly influence the {E}l {N}io/{S}outhern {O}scillation ({ENSO}) evolution. {T}his paper characterizes the spatio-temporal distribution of {E}asterly ({EWE}s) and {W}esterly {W}ind {E}vents ({WWE}s) and quantifies their relationship with intraseasonal and interannual large-scale climate variability. {W}e unambiguously demonstrate that the {M}adden-{J}ulian {O}scillation ({MJO}) and {C}onvectively-coupled {R}ossby {W}aves ({CRW}) modulate both {WWE}s and {EWE}s occurrence probability. 86 % of {WWE}s occur within convective {MJO} and/or {CRW} phases and 83 % of {EWE}s occur within the suppressed phase of {MJO} and/or {CRW}. 41 % of {WWE}s and 26 % of {EWE}s are in particular associated with the combined occurrence of a {CRW}/{MJO}, far more than what would be expected from a random distribution (3 %). {W}ind events embedded within {MJO} phases also have a stronger impact on the ocean, due to a tendency to have a larger amplitude, zonal extent and longer duration. {T}hese findings are robust irrespective of the wind events and {MJO}/{CRW} detection methods. {W}hile {WWE}s and {EWE}s behave rather symmetrically with respect to {MJO}/{CRW} activity, the impact of {ENSO} on wind events is asymmetrical. {T}he {WWE}s occurrence probability indeed increases when the warm pool is displaced eastward during {E}l {N}io events, an increase that can partly be related to interannual modulation of the {MJO}/{CRW} activity in the western {P}acific. {O}n the other hand, the {EWE}s modulation by {ENSO} is less robust, and strongly depends on the wind event detection method. {T}he consequences of these results for {ENSO} predictability are discussed.},
