Fig. \ref{fig: heatBudgetCycle} \ref{fig:heatBudgetCycle}  shows the heat budget annual cycle for MRI-CGCM3 averaged over the ocean grids within 30$^{\circ}$E--60$^{\circ}$ and 10$^{\circ}$S--10$^{\circ}$N as well as the corresponding historical$-$AMIP SST annual cycle difference. The mixed layer average temperature is approximated by SST when we estimate its tendency. Based on estimates of previous studies \citep{Schneider1996, deBoyer_2004MixedLayer}, a constant $25 m$ deep mixed layer is selected to estimate the heat storage change in the heat budget in this region. It can be seen from Fig. \ref{fig: heatBudgetCycle} \ref{fig:heatBudgetCycle}  that the sensible heat flux and the long wave radiation are much smaller in amplitude compared to other terms and the heat budget is balanced among heat storage tendency, latent heat flux, short wave radiation and ocean dynamics. %Colder SST anomalies are largely driven by excess latent flux during January--March and by ocean dynamical cooling during April--May. Warm SST anomalies during June--October are first driven by both reduced latent flux and ocean dynamics in June and then by pure ocean dynamical warming between July and October. Both the low short wave radiation and excess latent flux seem to drive the November and December cold SST anomalies.
