                         the associated synoptic features and the convection in the systems 
                         shown in satellite images. Cases of heavy precipitation in this 
                         region are identified in a climate simulation of present time and 
                         in a climate projection under global warming using the Regional 
                         Eta Model. The synoptic and mesoscale conditions, associated with 
                         heavy precipitation, simulated by the model are analyzed. The 
                         frequencies and intensities of extreme precipitation cases are 
                         obtained from four members of the simulations and projections, and 
                         an uncertainty analysis is performed with the results. One of the 
                         extreme precipitation cases is illustrated: the case that happened 
                         in Southeastern Brazil (Rio de Janeiro) from 31st December 2009 to 
                         1st January 2010. There were several landslides in the region, one 
                         of which destroyed a beach hotel killing many people. The 
                         satellite image showed the influence of several synoptic systems 
                         in the region, as the Bolivian High displaced from its normal 
                         position, the upper level cyclonic vortex close to Northeastern 
                         Brazil coast and a frontal system extending from the region 
                         towards the ocean. The synoptic condition, with low level wind 
                         confluence over the region, high relative humidity above 80% and 
                         strong divergence at high levels favored by the displacement of 
                         the Bolivian High southeastward contributed to the heavy 
                         precipitation associated with the oceanic squall line embedded in 
                         the frontal system. A simulation of this case with high resolution 
                         of Eta Model shows the ability of the model in representing the 
                         extreme precipitation.",
