The trajectory and the energetic of extratropical cyclones are analyzed using the NCEP/NCAR reanalysis in comparison with the model outputs CPTEC/COLA (T126L28) with GPSAS analysis. The analysis of the energetic and path of the cyclone formed over East Argentina on 23 August 2005 showed significant differences between the reanalysis and the model, especially in its track and magnitude. The comparison of the extratropical cyclone evolution, between reanalysis and the model, showed some considerable results such as: greater difference in the central pressure intensity of the extratropical cyclones; larger differences in kinetic energy after maximum cyclone intensity and a striking difference in the extratropical cyclone position.
