  abstract = {{T}wo coupled general circulation models, i.e., the {M}eteorological {R}esearch {I}nstitute ({MRI}) and {G}eophysical {F}luid {D}ynamics {L}aboratory ({GFDL}) models, were chosen to examine changes in mixed layer depth ({MLD}) in the equatorial tropical {P}acific and its relationship with {ENSO} under climate change projections. {T}he control experiment used pre-industrial greenhouse gas concentrations whereas the 2 x {CO}2 experiment used doubled {CO}2 levels. {I}n the control experiment, the {MLD} simulated in the {MRI} model was shallower than that in the {GFDL} model. {T}his resulted in the tropical {P}acific's mean sea surface temperature ({SST}) increasing at different rates under global warming in the two models. {T}he deeper the mean {MLD} simulated in the control simulation, the lesser the warming rate of the mean {SST} simulated in the 2 x {CO}2 experiment. {T}his demonstrates that the {MLD} is a key parameter for regulating the response of tropical mean {SST} to global warming. {I}n particular, in the {MRI} model, increased stratification associated with global warming amplified wind-driven advection within the mixed layer, leading to greater {ENSO} variability. {O}n the other hand, in the {GFDL} model, wind-driven currents were weak, which resulted in mixed-layer dynamics being less sensitive to global warming. {T}he relationship between {MLD} and {ENSO} was also examined. {R}esults indicated that the non-linearity between the {MLD} and {ENSO} is enhanced from the control run to the 2 x {CO}2 run in the {MRI} model, in contrast, the linear relationship between the {MLD} index and {ENSO} is unchanged despite an increase in {CO}2 concentrations in the {GFDL} model.},
