             abstract = "This work goals to study the influence of vertical resolution and 
                         convection parameterization schemes on the performance of the 
                         Global Eta Framework (GEF) model. The GEF model is based on the 
                         Eta regional model. The work seeks to better represent the 
                         stratosphere in the model and, consequently, improve predictions. 
                         The Betts-Miller-Janjic (BMJ) and Kain-Fritsch (KF) convective 
                         parameterizations were evaluated. The model was configured in a 
                         horizontal resolution of 25 km, with vertical resolutions of 50 
                         and 70 levels, and top in 1 hPa. The model was integrated daily 
                         for the month of January 2018, using the initial conditions of the 
                         Global Forecast System model (GFS) of 00Z. The simulation period 
                         was 10 days. The fifth and ninth day of the simulations were 
                         evaluated, using observational data from ERA5 reanalysis and NOAA 
                         CPC Morphing Technique (CMORPH) precipitation. The precipitation 
                         simulations showed that the increase in vertical resolution 
                         resulted in a slight improvement in the KF scheme, however the BMJ 
                         experiment with 50 levels showed the best performance. In 
                         comparison with the ERA5 reanalysis, the temperature at 5 hPa is 
                         best represented with 70 vertical levels, by the two convective 
                         schemes. The large-scale patterns of pressure at mean sea level, 
                         temperature at 2 meters and at 850 hPa are reproduced by the 
                         experiments, however, the regions of higher latitudes showed the 
                         greatest differences compared with reanalysis. In general, the 
                         results showed that the GEF model performed better in the 
                         configuration with 50 vertical levels and with the BMJ convective 
                         scheme for precipitation, pressure and flow in 250 hPa. However, 
                         the configuration with 70 levels resulted in an improvement in 
                         temperature in 250 hPa and 5 hPa and also in the flow in 5 hPa, in 
                         both convective schemes. The simulations also reproduced the mean 
                         vertical structure of the temperature and the zonal component (u) 
                         well, especially in the lower atmosphere. Thus, this study 
                         contributes to the development and improvement of the performance 
                         of the GEF model.",
