                         performance of the WRF-ARW model (version 3.2.1) to predict the 
                         winds at the Alcantara Launch Center applying it operationally on 
                         rocket launching occasions. Seasonal analysis of the model 
                         behavior were performed against two radiosonde data sets, which 
                         represent the dry (strong winds) and rainy (weak winds) seasons. 
                         72 hours forecasts were made from initial conditions provided by 
                         the Global Forecasting System (GFS/NCEP). Simulations configured 
                         for three nested grid domains, maximum 1 km horizontal resolution 
                         and 42 vertical levels were compared with observations at each 6 
                         hours through the Willmott index of agreement (d). Initial tests 
                         of sensitivity were made for comparison and adjustment of 
                         different physical and dynamic parameters, like size of domains, 
                         number of vertical levels, spin-up time and Planetary Boundary 
                         Layer parameterizations. The model was able to represent the 
                         vertical wind profile, showing no difference in performance 
                         between the dry or rainy seasons and reaching maximum values of d 
                         in the order of 0.90. Overall, the model overestimated the layers 
                         average wind components (U and V) up to 3.0 m/s with respect to 
                         the observations.",
