                         interannual climate variability of the CPTEC/COLA Atmospheric GCM 
                         is assessed for several regions of the tropics and extratropics. 
                         The evaluation is made for the period 1982-91 for an ensemble run 
                         of 9 realizations of the model forced by observed global sea 
                         surface temperature (SST)anomalies. The Brier Skill Score is used 
                         to assess the precipitation simulated by the model for several 
                         regions of South America, Africa and Asia during the peak of their 
                         rainy seasons. Interannual climate variability in Northeast 
                         Brazil, Amazonia, and southern Argentina-Uruguay and to a lesser 
                         degree for Sahel and Eastern Africa rainfall are well simulated by 
                         the model. The model exhibits lower skill in reproducing 
                         interannual rainfall variability in the monsoon regions of world 
                         and southern Africa, indicating that simulation on interannual 
                         variations of climate in those regions still remains problematic, 
                         possibly due to the effect of land-surface moisture and snow 
                         feedbacks that would indicate the important role of internal 
                         climate variability in those regions, besides the SST external 
                         forcing. The model captures the well known signatures of rainfall 
                         and circulation anomalies of El Ni¤o 1982-83, indicating its 
                         sensitivity to strong external forcing, while in normal years, the 
                         internal climate variability can affect the predictability of 
                         climate in some regions, especially the monsoon areas of the 
                         world.",
