| Abstract | O presente trabalho objetivou a realização de uma análise criteriosa dos perfis de velocidade e direção do vento e as características dos sistemas atmosféricos associados, com base nos dados de vento coletados pela Torre Anemométrica(TA) do Centro de Lançamento de Alcântara (CLA), inclusive verificando-se a qualidade dos dados coletados neste centro. Os dados de vento coletados na TA são do período de 1995 a 1999, obtidos em seis níveis diferentes (6,0; 10,0; 16,3; 28,5; 43,0 and 70,0 m). Para análise dos dados foram ajustadas as distribuições estatísticas Beta, Normal e Weibull, identificando a melhor aproximação do conjunto às distribuições. A distribuição de Weibull, para o período de estudo, apresentou bom ajuste para valores entre 3,0 ms^1 e 9 ms^1 e a distribuição Normal apresentou bom ajuste para valores entre 4,0 ms^1 e 9,0 ms^1. A correlação entre os valores de velocidade e direção do vento para os níveis da TA foi realizada e os resultados mostraram de que os perfis estão superiores a 0,70 indicando forte correlação entre os níveis. Foi utilizada a técnica de Análise das Componentes Principais (ACP) nos perfis verticais de vento, a qual permitiu a análise das estruturas existentes nos perfis e a identificação da influência dos sistemas atmosféricos nos perfis verticais do vento. As componentes principais da direção da velocidade para a época chuvosa (representada pelo mês de março) apresentam percentuais de 60% na 1ACP, 20% para a 2ACP e 10% para 3 ACP, estes associados às freqüências dos sistemas atuantes no CLA. A análise da ACP da velocidade do vento na 1ACP apresentou percentual superior a 93%, em ambos os períodos (chuvoso ou seco) associado a um processo físico predominante na região do CLA (brisa marítima). Foi também realizado um estudo de caso da estação chuvosa (março) de 2005, visando analisar os perfis de vento e sistemas atmosféricos. 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 Alcântara 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. | |||
