                         was configured to run over the South America continent. This 
                         limited area model has 38 layers in the atmosphere, and its domain 
                         includes part of the adjacent Atlantic and Pacific Oceans. The 
                         model was setup to perform 1 month forecasts. The version used in 
                         these preliminary experiments uses a bucket model to describe 
                         water in the ground and a modified Betts-Miller scheme for 
                         producing convective precipitation. The experiments used constant 
                         sea surface temperature held and initial soil moisture from 
                         climatology. Results obtained from a dry season month and a rainy 
                         season month over South America in 1997 show that the 
                         reinitialization of model at short range forecasts is not 
                         necessary as was done with the previous version of the model. 
                         These results show no obvious drying of the atmosphere or tendency 
                         with time of the domain average surface pressure. In both cases 
                         (dry and wet)the model seems to have reproduced the climatological 
                         signal of the forecast months. The monthly accumulated total p 
                         recipitation agrees well with the observations. These runs showed 
                         that the current configuration of the eta model is stable and 
                         capable of producing continuous extended range runs over South 
                         America.",
