MAGNAGO, Roberto; FISCH, Gilberto  e  MORAES, Osvaldo. Spectral analysis of the surface winds at the Alcântara Lauching Center (CLA). Rev. bras. meteorol. [online]. 2010, vol.25, n.2, pp.260-269. ISSN 0102-7786.

In this work is analyzed the spectral characteristics of atmospheric turbulence in the Alcântara Launching Center (CLA), which suffers the influence of a cliff and of the sea breeze coming from the ocean. The atmospheric spectra were determined for the 3 wind components (u, v, and w) in the superficial boundary layer, to be used for the Research and Developpment (R&D) of sounding rockets and Satellite Launch Vehicle (VLS) build by IAE. The data were collected during the month of August, 1999 using a 3D sonic anemometer. Results involving the σu/u*, σv/u* and σw/u* relations are obtained, and are all consistent with those reported in literature.

Palavras-chave : Wind turbulent spectra; coastal cliff; flat terrain.
