		<abstract>Neste trabalho focamos a análise na capacidade do modelo de circulação geral da atmosfera de alta resolução, 20 km conduzido com o Earth Simulator, em simular os padrões climáticos sobre a América do Sul no clima presente. A comparação dos resultados do modelo com as observações mostrou resultados promissores na capacidade do modelo em simular os padrões sazonais, tal como ZCAS. Em geral, o modelo reproduz a distribuição espacial e temporal da precipitação e temperatura. Comparando o modelo de 20 km com outros de maior resolução, os resultados indicam que o modelo de 20 km apresenta um melhor desempenho. ABSTRACT: This study is focused on evaluating the capability of the very high horizontal resolution atmospheric general circulation model, with 20-km grid size conducted on the Earth Simulator in simulating the present-day climate over South America. The comparison of the model and the observational dataset yields rather promising results on the representation of the mean climate seasonal features. The model reproduces realistic seasonal mean spatial patterns in terms of geographical distribution, such as SACZ. Experiments of the dependency of the horizontal resolution on the reproducibility of the present-day have revealed that the 20-km model generally exhibits higher performance than a model with a lower horizontal resolution.</abstract>
