                         ABSTRACT: This study aimed to conduct a thorough analysis of the 
                         profiles of wind speed and direction and the atmospheric systems 
                         characteristics associated with the data collected by the Tower of 
                         Wind or Anemometric Tower (TA) at the Alc{\^a}ntara Launching 
                         Center, including the verification of the data quality collected 
                         in this center. The wind data was collected at the TA from the 
                         period from 1995 to 1999 and it was obtained in six different 
                         levels (6,0; 10,0; 16,3; 28,5; 43,0 and 70,0 m). The statistical 
                         distributions Beta, Normal and Weibull distribution were adjusted 
                         for analysis, identifying the best approximation of the complex to 
                         the distributions. The Weibull distribution for the period of 
                         study presented a good adjustment for values between 3.0 and 9 
                         ms-1 as well as the and Normal distribution a good adjustment for 
                         values between 4.0 and 9.0 ms-1. The correlation between the 
                         values of wind speed and direction for the levels of TA was 
                         performed and the results showed that the profiles are higher than 
                         0.70 (strong correlation). The study made use of the technique of 
                         Principal Components Analysis (PCA) in vertical profiles of wind 
                         which allowed the identification of existing structures in the 
                         profiles and the identification of the influence of atmospheric 
                         systems in wind vertical profiles. The components of the direction 
                         of speed for the rainy season (March) present percentage of 60% in 
                         1ACP, 20% for 2ACP and 10% for 3 ACP. This information is 
                         associated with the frequencies of the systems operating in the 
                         CLA. Regarding the analysis of wind speed of ACP, it was presented 
                         in 1ACP percentage above 93%, in both periods (rainy or dry) 
                         associated with a predominant physical process in the CLA. It was 
                         also carried out a case study on a rainy season in March 2005 in 
                         order to analyze the wind profiles and the atmospheric systems. 
                         According to this paper, it is possible to identify and the 
                         understanding of the dynamics existing in the superficial limit 
                         layer in the CLA.",
