                         sensitive to initial conditions, in other words they are chaotic. 
                         The ensemble weather prediction was originated from this new 
                         conception of the atmosphere since the initial conditions used for 
                         models have intrinsic uncertainties. Basically, the ensemble 
                         weather prediction consists to produce perturbed initial 
                         conditions and to run for several times the same model from this 
                         perturbed initial conditions. In October 2001, the Center for 
                         Weather Forecast and Climate Studies (CPTEC) started the 
                         operational ensemble weather forecasting. In this paper the CPTEC 
                         ensemble weather prediction system, the metodology for 
                         construction of perturbed initial conditions and some products 
                         that are being generated from this system are shown.",
