  abstract = {{T}he relationship between the large-scale intraseasonal variability, synoptic wind regimes, and the local daily variability of precipitation over the main island of {N}ew {C}aledonia (southwest tropical {P}acific) is investigated with a focus on the austral summer wet season ({N}ovember-{A}pril). {T}he average diurnal cycle of precipitation over the island is characterized by a sharp afternoon maximum around 1600 local time, with significant differences between the windward east coast, the leeward west coast, and the mountain range. {T}he afternoon peak is related to the afternoon sea-breeze circulation and to the diurnal cycle of convection over land. {I}n general, its magnitude follows the same evolution as the daily mean. {I}n agreement with past studies, a clear modulation of the {M}adden-{J}ulian oscillation ({MJO}) on both the diurnal cycle of precipitation and the probability of occurrence of four robust wind regimes can be identified in the {N}ew {C}aledonia region during the wet season. {F}rom the evidence that there is a qualitative correspondence between the effects of both the {MJO} phases and the wind regimes on features in the diurnal cycle of precipitation, a simple model is proposed to inspect the {MJO} forcing mediated by wind regimes on the diurnal variability of rain. {T}he complete decomposition of the {MJO} impact shows that the modulation of diurnal cycle by the {MJO} relies on complex interactions between the {MJO} and synoptic winds that involve both large-scale {MJO} convective anomalies and {MJO}-induced modification of wind patterns.},
