O objetivo deste trabalho é avaliar a eficiência do modelo RegCM4 em reproduzir as precipitações sazonais sobre a Amazônia no clima atual (1979-2014), com referência ao conjunto de dados do GPCP. De maneira geral, os resultados mostraram que o RegCM4 reproduziu de maneira satisfatória os padrões sazonais de precipitação na Região. Contudo, as análises quantitativas demonstraram que o RegCM4 apresenta erros sistemáticos de subestimativa (viés negativo) no verão e outono, e superestimava (viés positivo) no inverno e primavera. Além disso, foi investigado o desempenho do modelo em reproduzir os padrões anômalos sazonais de precipitação. Os resultados demonstraram uma boa concordância entre as anomalias de chuva observadas e simuladas no período estudado.Downloads
