We also notice that the coupling-induced biases of East African precipitation and the Indian Ocean SSTs in the model MRI-CGCM3 (Fig. \ref{fig:prMon} and Fig. \ref{fig:TsMon}) are accompanied by dry biases of the Indian summer monsoon. Recent studies have shown that SST biases over the Indian Ocean \citep{Prodhomme_2014IObias}, including the cold bias of the Arabian Sea \citep{Levine_2013ArabianSea}, could contribute to the dry Indian summer monsoon in coupled models relative to observations or their corresponding SST-forced simulations. However, a dry Indian summer monsoon could impact Indian Ocean SSTs and East African precipitation via change of the surface winds over the Indian Ocean. Drier summer India implies a weak monsoon circulation, including the low level winds in the Somali jet region.  This could lead to reduced evaporation and weakened coastal upwelling over the western Indian Ocean off the coast of East Africa, and  warm the SST biases. This is consistent with the analysis of SST biases in the coupled models. However, this anomalous atmospheric forcing is most likely a feedback rather than the cause of the SST bias over the western Indian Ocean, as illustrated in the surface heat budget difference between the MRI-CGCM3 AMIP run and the ERA-Interim reanalysis in Fig. \ref{fig:heatBudgetCycleAmipMinusERAI}. The latent heat flux difference (green solid line) is negative year round over the western Indian Ocean and thus is continually cooling the SSTs there. Therefore, the cause of the western Indian Ocean SST bias is from the ocean component of the atmosphere-ocean coupled system.
