Abstract

Multiresolution spectra of both horizontal and vertical wind components observed at a 140-m micrometeorological tower are analysed. The tower is located at the township of Linhares, ES, Brazil, at 4 km from the coast and nest to a thermal power plant. At nighttime, the spectral maximum is located at the largest temporal scales analyzed, being therefore related to nonturbulent low-frequency processes. During the day, spectral maxima of the horizontal wind components show little variation above 20 m.
For the vertical component, on the other hand, the temporal scale of such maxima increases steadily with height.
