             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.",
