  abstract = {{T}he strongest large-scale intraseasonal (30-110 day) sea surface temperature ({SST}) variations in austral summer in the tropics are found in the eastern {I}ndian {O}cean between {A}ustralia and {I}ndonesia ({N}orth-{W}estern {A}ustralian {B}asin, or {NWAB}). {TMI} and {A}rgo observations indicate that the temperature signal (std. similar to 0.4 {A} degrees {C}) is most prominent within the top 20 m. {T}his temperature signal appears as a standing oscillation with a 40-50 day timescale within the {NWAB}, associated with similar to 40 {W}m(-2) net heat fluxes (primarily shortwave and latent) and similar to 0.02 {N}m(-2) wind stress perturbations. {T}his signal is largely related to the {M}adden-{J}ulian {O}scillation. {A} slab ocean model with climatological observed mixed-layer depth and an ocean general circulation model both accurately reproduce the observed intraseasonal {SST} oscillations in the {NWAB}. {B}oth indicate that most of the intraseasonal {SST} variations in the {NWAB} in austral winter are related to surface heat flux forcing, and that intraseasonal {SST} variations are largest in austral summer because the mixed-layer is shallow (similar to 20 m) and thus more responsive during that season. {T}he general circulation model indicates that entrainment cooling plays little role in intraseasonal {SST} variations. {T}he larger intraseasonal {SST} variations in the {NWAB} as compared to the widely-studied thermocline-ridge of the {I}ndian {O}cean region is explained by the larger convective and air-sea heat flux perturbations in the {NWAB}.},
