abstract = "An 80-km National Centers for Environmental Prediction eta model
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.",
