abstract = "Global Eta Framework (GEF) is a global atmospheric model developed
in general curvilinear coordinates and capable of running on
arbitrary rectangular quasi-uniform spherical grids, using
stepwise (Eta) representation of the terrain. In this study, the
model is run on a cubed-sphere grid topology, in a version with
uniform Jacobians (UJ), which provides equal-area grid cells, and
a smooth transition of coordinate lines across the edges of the
cubed-sphere. Within a project at the Brazilian Center for Weather
Forecasts and Climate Studies (CPTEC), a nonhydrostatic version of
this model is under development and will be applied for seasonal
prediction studies. This note describes preliminary tests with the
GEF on the UJ cubed-sphere in which model performance is evaluated
in seasonal simulations at a horizontal resolution of
approximately 25 km, running in the hydrostatic mode. Comparison
of these simulations with the ERA-Interim reanalyses shows that
the 850 hPa temperature is underestimated, while precipitation
pattern is mostly underestimated in tropical continental regions
and overestimated in tropical oceanic regions. Nevertheless, the
model is still able to well capture the main seasonal climate
characteristics. These results will be used as a control run in
further tests with the nonhydrostatic version of the model.",
