                         performed monthly at CPTEC/INPE in Brazil, and previous studies 
                         have shown that there is different predictability in different 
                         areas of South America. The models show higher skill in the 
                         tropical and extratropical regions than in the subtropical region 
                         of South America, which is a transition region, between the 
                         tropical regime and the middle latitude regime. The AGCM 
                         CPTEC/COLA and the regional Eta model are used to the predictions, 
                         in ensemble integrations. In this study, climate simulations from 
                         both models are used to analyse the interannual and intraseasonal 
                         variability over several areas of South America. ENSO features and 
                         intraseasonal variability related to MJO and PSA pattern are 
                         discussed and compared to observations. Opposite relations in 
                         precipitation between north/northeast and south/southwest South 
                         America, found in observations, are represented by themodel in the 
                         interannual and intraseasonal timescale. Additional results from 
                         experiments using different CO2 concentration in climate 
                         simulations are analysed to identify changes in the interannual
