  abstract = {{A} global ocean general circulation model ({OGCM}) is used to investigate the mixed layer heat budget of the northern {I}ndian {O}cean ({NIO}). {T}he model is validated against observations and shows fairly good agreement with mixed layer depth data in the {NIO}. {T}he {NIO} has been separated into three subbasins: the western {A}rabian {S}ea ({AS}), the eastern {AS}, and the {B}ay of {B}engal ({B}o{B}). {T}his study reveals strong differences between the western and eastern {AS} heat budget, while the latter basin has similarities with the {B}o{B}. {I}nteresting new results on seasonal time scales are shown. {T}he penetration of solar heat flux needs to be taken into account for two reasons. {F}irst, an average of 28 {W} m(-2) is lost beneath the mixed layer over the year. {S}econd, the penetration of solar heat flux tends to reduce the effect of solar heat flux on the {SST} seasonal cycle in the {AS} because the seasons of strongest flux are also seasons with a thin mixed layer. {T}his enhances the control of {SST} seasonal variability by latent heat flux. {T}he impact of salinity on {SST} variability is demonstrated. {S}alinity stratification plays a clear role in maintaining a high winter {SST} in the {B}o{B} and eastern {AS} while not in the western {AS}. {T}he presence of freshwater near the surface allows heat storage below the surface layer that can later be recovered by entrainment warming during winter cooling (with a winter contribution of + 2.1 degrees {C} over left right {C} in the {B}o{B}). {O}n an interannual time scale, the eastern {AS} and {B}o{B} are strongly controlled by the winds through the latent heat flux anomalies. {I}n the western {AS}, vertical processes, as well as horizontal advection, contribute significantly to {SST} interannual variability, and the wind is not the only factor controlling the heat flux forcing.},
