  abstract = {{T}his paper presents the {NOW} regional coupled ocean-atmosphere model built from the {NEMO} ocean and {WRF} atmospheric numerical models. {T}his model is applied to the tropical {I}ndian {O}cean, with the oceanic and atmospheric components sharing a common 1/4 degrees horizontal grid. {L}ong experiments are performed over the 1990-2009 period using the {B}etts-{M}iller-{J}anjic ({BMJ}) and {K}ain-{F}ritsch ({KF}) cumulus parameterizations. {B}oth simulations produce a realistic distribution of seasonal rainfall and a realistic northward seasonal migration of monsoon rainfall over the {I}ndian subcontinent. {A}t subseasonal time scales, the model reasonably reproduces summer monsoon active and break phases, although with underestimated rainfall and surface wind signals. {I}ts relatively high resolution results in realistic spatial and seasonal distributions of tropical cyclones, but it fails to reproduce the strongest observed cyclone categories. {A}t interannual time scales, themodel reproduces the observed variability associated with the {I}ndian {O}cean {D}ipole ({IOD}) and the delayed basin-wide warming/cooling induced by the {E}l {N}ino {S}outhern {O}scillation ({ENSO}). {T}he timing of {IOD} occurrence in the model generally matches that of the observed events, confirming the influence of {ENSO} on the {IOD} development (through the effect of lateral boundary conditions in our simulations). {A}lthough the {KF} and {BMJ} simulations share a lot in common, {KF} strongly overestimates rainfall at all time scales. {KF} also overestimates the number of simulated cyclones by a factor two, while simulating stronger events (up to 55 m s(-1)) compared to {BMJ} (up to 40 m s(-1)). {T}hese results could be related to an overly active cumulus parameterization in {KF}.},
