Abstract This study investigated the sensitivity models coupled ocean-atmosphere of CMIP3 and CMIP5 for the period of 1979-1999 to simulate the magnitude of the meridional gradient of sea surface temperature anomalies (SST) in Atlantic Tropical. In the results are presented to comparative analyses for this meridional gradient of SST anomalies of two seasonal seasons (summer and autumn autrais). The results showed the evolution of the models in simulating the variations of SST anomalies of this gradient from CMIP3 to CMIP5. For CMIP3 the models did not good perform in both seasons. For the CMIP5 the summer presented the highest number of models with Willmott performance index (equal to or above the median ID ≥ 0.6).
