abstract = "The Eta Model is used operationally by INPE at the Centre for
Weather Forecasts and Climate Studies (CPTEC) to produce weather
forecasts over South America since 1997 and seasonal climate
forecasts since 2002. The model has gone through upgrades along
these years and is able to produce decadal integrations to
downscale climate projections. Likewise, the INPE global
atmospheric model has been coupled to MOM4 ocean model and decadal
integrations in the period 1960-2105 was produced and contributed
to the CMIP5 dataset. The development of the Brazilian Earth
System Model (BESM) has been ongoing parallel to the development
of the Brazilian regional earth system model (BESM-R). The
objective of this work is to evaluate the regional Eta model
nested in the BESM in the present climate simulations, from
1961-1990. The Eta model was con\figured with 20-km
horizontal resolution and 38 layers, in a domain covering all
South America. In the lower boundary, sea surface temperature was
provided by the BESM and was updated daily during the regional
integration, whereas the lateral boundaries were updated every 6
hours with the BESM atmospheric conditions. Continuous 30-year
integrations were carried out by the regional model. Large scale
circulation pattern at upper and low levels are shown in
comparison with the respective BESM \flow and evaluated
against reanalyses. The regional model shows improvement in the
precipitation and temperature pattern over the continent. Seasonal
cycle of precipitation and temperature are also shown.",
