abstract = "This study shows the results from a regional climate simulation of
the present-day climate, corresponding to the period 1961-1970
over South America, using the regional Eta Model nested within the
HadAM3P model from the UK Hadley Centre. The simulation analysis
is focused on assessing the capability of the nested regional
model in representing spatial patterns of seasonal mean climate
and the annual cycle of precipitation and temperature. The goals
of this 10-year run for South America are to verify if the Eta
Model can be used in climate-change scenarios and to verify if
this model has the ability to generate added value for the South
American continent. The Eta Model was chosen because there are few
investigations using the Eta Model for long integrations over
South America and because the vertical coordinate system used in
this model is recommended for use over South America due to the
presence of the Andes range. In the present 10-year simulation,
the regional model reproduced many of the South American mesoscale
climate features and together added new value to the driver model.
Value was also added to the driver model by reducing seasonal
biases in austral winter relative to austral summer. The regional
model also exhibits better performance in the representation of
low-level circulation, such as the topographically induced
northwesterly flux. © 2009 Springer-Verlag.",
