  abstract = {{S}ea-surface temperature interannual anomalies ({SSTA}s) in the thermocline ridge of the southwestern tropical {I}ndian {O}cean ({TRIO}) have several well-documented climate impacts. {I}n this paper, we explore the physical processes responsible for {SSTA} evolution in the {TRIO} region using a combination of observational estimates and model-derived surface layer heat budget analyses. {V}ertical oceanic processes contribute most to {SSTA} variance from {D}ecember to {J}une, while lateral advection dominates from {J}uly to {N}ovember. {A}tmospheric fluxes generally damp {SSTA} generation in the {TRIO} region. {A}s a result of the phase opposition between the seasonal cycle of vertical processes and lateral advection, there is no obvious peak in {SSTA} amplitude in boreal winter, as previously noted for heat content anomalies. {P}ositive {I}ndian {O}cean {D}ipole ({IOD}) events and the remote influence of {E}l {N}ino induce comparable warming over the {TRIO} region, though {IOD} signals peak earlier ({N}ovember-{D}ecember) than those associated with {E}l {N}ino (around {M}arch-{M}ay). {M}echanisms controlling the {SSTA} growth in the {TRIO} region induced by these two climate modes differ strongly. {W}hile {SSTA} growth for the {IOD} mostly results from southward advection of warmer water, increased surface shortwave flux dominates the {E}l {N}ino {SSTA} growth. {I}n both cases, vertical oceanic processes do not contribute strongly to the initial {SSTA} growth, but rather maintain the {SSTA} by opposing the effect of atmospheric negative feedbacks during the decaying phase.},
