%X An 80 km NCEP Eta model was configured to run over South American continent. This limited area model has 38 layers in the atmosphere and its domain includes part of the adjoining Atlantic and Pacific Oceans. The model was setup to perform one month forecasts. Results obtained from a dry season month and a rainy season month over South America in 1997 showed that the re-initialization of model at short range forecasts is not necessary. Diagnostics showed good mass conservation and no drying tendency, suggesting model stability for longer integrations. Both cases (dry and wet) reproduced the climatological signal of the forecasted months. The monthly accumulated total precipitation agrees well with the observations. These long-term runs using the Eta model over South America show satisfactory regional climate forecasts for this continent.
