                         Mesoscale Cyclonic Vortex (MCV) is associated to the South 
                         Atlantic Convergence Zone (SACZ) through a feedback process. This 
                         system, simulated by the BRAMS regional model, is generated 
                         embedded in a stratiform environment within the SACZ region, 
                         during the January 2009 austral summer. MCVs present similar 
                         characteristics which could be considered as a signature for such 
                         systems. The case study also presents a lifetime shorter than 24 h 
                         and spatial scale of approximately 200 km2 in addition to intense 
                         precipitation, shifting in the flow direction in the lower 
                         troposphere. In the case occurred in the Mato Grosso State, the 
                         presence of this system was associated with heavy rain, relative 
                         vorticity of the same order as the Coriolis parameter (10-4 s-1), 
                         warm core above the level of maximum intensity and rapid growth of 
                         the cyclonic vorticity center mostly in the lower levels. The 
                         simulated precipitation is compared against the Hidroestimador 
                         precipitation product. The results suggest that the BRAMS model, 
                         configured with high spatial and temporal resolutions improves the 
                         representation of the MCVs when compared to the NCEP CFSR
