             abstract = "The transition of the dry to wet season in the Southern Amazon is 
                         characterized by the sudden increase of the latent heat source. In 
                         large scale models the parameterization of the latent heat source 
                         is considered to be a major source of uncertainty. Thus, it is 
                         reasonable to consider the impact of different cumulus 
                         parameterizations in the transition process in the CPTEC global 
                         circulation model. A set of experiments, based on the operational 
                         seasonal forecasting cycle, were performed with the traditional 
                         Kuo (K) scheme, as the control, and two experiments with the 
                         Relaxed Arakawa-Schubert (RAS). It is shown that the diurnal cycle 
                         of precipitation in the control produces maximum values in the 
                         morning while the RAS delays the maximum precipitation to the 
                         afternoon. Thus, the RAS is shown to produce more realist results. 
                         Significant differences are also found in the surface fluxes of 
                         heat and moisture as the RAS is shown to be more realist that the 
                         traditional Kuo scheme. Further experiments with the Grell scheme 
                         will also be shown and compared to the other two schemes.",
