                         utilizados dados m{\'e}dios mensais de temperatura da

                         e que o segundo modo ilustra a variabilidade interanual associada

                         present work was to analyze the South American Monsoon System 
                         (SAMS) variability, and its relation to the Pacific Decadal 
                         Oscillation (PDO) phases. The relations of SAMS with other monsoon 
                         systems were also investigated. In order to investigate this 
                         variability, monthly anomalies of the deviation from the annual 
                         mean of the zonal deviation field of the velocity potential (X*') 
                         at 200hPa for the 1948-1999 period were subjected to the Empirical 
                         Orthogonal Function analysis. Additional monthly data of the sea 
                         surface temperature, surface air temperature, sea level pressure, 
                         vertical velocity at 500hPa, precipitable water and streamfunction 
                         at 200hPa were also used. Anomaly composites of these variables 
                         were obtained in near global areas using the cases selected for 
                         threshold of ±0.5 standard deviations of the principal components 
                         of the first two EOF modes of the analysis of X*' at 200hPa in 
                         South America. The dominant mode of this analysis describes the 
                         PDO related multi-decadal variability of the SAMS, while the 
                         second mode illustrates the El Niño/Southern Oscillation (ENSO) 
                         related interannual variability. The EOF analysis of X*' at 200hPa 
                         in the global band shows that the SAMS and the East Asia monsoon 
                         system are related each other in the multi-decadal scale, and the 
                         North America monsoon and the Indian monsoon systems are related 
                         in the interannual scale.",
