                         melhor a estratosfera no modelo e consequentemente, melhorar as 
                         previs{\~o}es. Foram avaliadas as parametriza{\c{c}}{\~o}es 
                         convectivas de Betts-Miller-Janjic (BMJ) e Kain-Fritsch (KF). O 
                         modelo foi configurado na resolu{\c{c}}{\~a}o horizontal de 25 
                         km, resolu{\c{c}}{\~o}es verticais de 50 e 70 n{\'{\i}}veis, e 
                         topo em 1 hPa. O modelo foi integrado diariamente para o m{\^e}s 
                         de janeiro de 2018, utilizando as condi{\c{c}}{\~o}es iniciais 
                         do modelo Global Forecast System (GFS) das 00Z. O prazo de 
                         simula{\c{c}}{\~a}o foi de 10 dias. Foram avaliados o quinto e 
                         nono dia do conjunto das simula{\c{c}}{\~o}es. As 
                         simula{\c{c}}{\~o}es de precipita{\c{c}}{\~a}o mostraram que o 
                         aumento da resolu{\c{c}}{\~a}o vertical resultou em ligeira 
                         melhora no esquema KF, entretanto o experimento BMJ com 50 
                         n{\'{\i}}veis apresentou o melhor desempenho. Em 
                         compara{\c{c}}{\~a}o com a rean{\'a}lise do ERA5, a temperatura

                         apresentaram as maiores diferen{\c{c}}as comparadas com a 
                         rean{\'a}lise. Em geral, os resultados mostraram que o modelo GEF 
                         apresentou melhor desempenho na configura{\c{c}}{\~a}o com 50 
                         n{\'{\i}}veis verticais e com o esquema convectivo de BMJ para a 
                         precipita{\c{c}}{\~a}o, press{\~a}o e escoamento em 250 hPa. 
                         Entretanto, a configura{\c{c}}{\~a}o com 70 n{\'{\i}}veis 
                         resultou melhora na temperatura em 250 hPa e 5 hPa e tamb{\'e}m 
                         no escoamento em 5 hPa, em ambos os esquemas convectivos. Desta 
                         forma, este estudo contribui no desenvolvimento e na melhora do 
                         desempenho do modelo GEF. 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 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, 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. 
                         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. Thus, this 
                         study contributes to the development and improvement of the 
                         performance of the GEF model.",
