             abstract = "Recent studies show that different types of ENSO influence the 
                         atmospheric fields differently. In this study, precipitation 
                         anomalies and extreme events over South America are analysed with 
                         relation to two types of ENSO [East (strong Sea Surface 
                         Temperature Anomalies (SSTA) on East Pacific) and Central (strong 
                         SSTA on Central Pacific)]. The composites of precipitation 
                         anomalies, during these two types of ENSO, show that there are 
                         different patterns, e.g. during austral summer of Central El Niņo 
                         (CEN) there are negative precipitation anomalies in eastern Brazil 
                         that do not exist in East El Niņo (EEN), whereas in southern 
                         Brazil there are positive precipitation anomalies during EEN that 
                         do not exist in CEN. Furthermore, the anomalies are mostly 
                         stronger and more extensive during EEN (Central La Niņa CLN) than 
                         in CEN (East La Niņa ELN), although there are some exceptions, 
                         such as during austral spring in southern Brazil, where anomalies 
                         during CEN (ELN) are stronger than during EEN (CLN). The anomalous 
                         frequency of extreme precipitation events shows generally patterns 
                         consistent with the anomalous precipitation behaviour, though the 
                         patterns are not always coincident, because the regions with 
                         significant increase of frequency of extreme events tend to be 
                         more extensive than those with increased seasonal precipitation. 
                         When the monthly or seasonal atmospheric anomalies associated with 
                         a type of ENSO episode are very similar (opposite) to the 
                         atmospheric anomalies associated with extreme precipitation in a 
                         certain region, then a significant enhancement (suppression) of 
                         the frequency of extreme events is observed in that region during 
                         this type of episode.",
