The results show that for the present climate the model simulates well the spatial distribution of extreme temperature and rainfall events when compared with observations, with temperature the more realistic. The observations over the region are far from comprehensive which compromises the assessment of model quality. In all the future climate scenarios considered all parts of the region would experience significant and often different changes in rainfall and temperature extremes. In the future, the occurrence of warm nights is projected to be more frequent in the entire tropical South America while the occurrence of cold night events is likely to decrease. Significant changes in rainfall extremes and dry spells are also projected. These include increased intensity of extreme precipitation events over most of Southeastern South America and western Amazonia consistent with projected increasing trends in total rainfall in these regions. In Northeast Brazil and eastern Amazonia smaller or no changes are seen in projected rainfall intensity though significant changes are seen in the frequency of consecutive dry days. %@mirrorrepository sid.inpe.br/mtc-m18@80/2008/03.17.15.17.24 %8 Jan %T Future change of temperature and precipitation extremes in South America as derived from the PRECIS regional climate modeling system %@electronicmailaddress marengo@cptec.inpe.br %@electronicmailaddress %@electronicmailaddress %@electronicmailaddress maria.valverde@cptec.inpe.br %@secondarytype PRE PI %K downscaling, climate change, vulnerability. %@group CST-CST-INPE-MCT-BR %@e-mailaddress deicy@cptec.inpe.br %@secondarykey INPE--PRE/ %@secondarymark A1_CIÊNCIAS_AGRÁRIAS A2_GEOCIÊNCIAS A1_INTERDISCIPLINAR %@issn 0899-8418 %2 sid.inpe.br/mtc-m18@80/2009/08.03.14.06.56 %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %B International Journal of Climatology %4 sid.inpe.br/mtc-m18@80/2009/08.03.14.06 %D 2009 %V ** %@doi 10.1002/joc.1863 %A Marengo, José Antônio, %A Rones, J., %A Alves, Lincoln Muniz, %A Valverde, Maria Cleofe, %@dissemination WEBSCI; PORTALCAPES; MGA; COMPENDEX. %@area CST
