The BRAMS regional model was used to simulate the large scale environment and the vertical profile of some meteorological variables, to the most precipitant CMS that reaches RS, from November 2002 to February 2003. The CMS selected was observed from 02/19/2003 to 02/20/2003. The model simulation, with one hour issues, allowed to detail the synoptic environment where the CMS was during its life cycle, being able to reproduce the suitable conditions to its beginning, development and dissipation. It was possible too, describe the behavior of the vertical profiles of the wind, specific humidity, vertical velocity and equivalent potential temperature, to each phase of the CMS life cycle.
