		<abstract>Trocas de massa e momentum entre o oceano e a atmosfera são significamente influenciadas pela presença da agitação marítima. O experimento HEXOS coletou dados de vento, stress e espectro de ondas, que possibilitaram entender e propor formulações que relacionassem wave-age com o comprimento de rugosidade. Neste artigo, as formulações de Smith e Volkov foram aplicadas em um modelo de Camada de Fluxo Constante com os fluxos parametrizados com a teoria de similaridade. Os resultados mostram que a formulação de Volkov prevê cerca de 30 por cento de redução do vento de superfície, na presença de ondas com período de pico entre 5 e 12 segundos. ABSTRACT: Momentum and mass exchange between the sea and atmosphere are significantly influenced by sea-waves. The HEXOS experiment collected wind, stress and wave spectrum information resulting in new insights and to give new formulations relating surface roughness and wave age. In this article the formulations from Smith and Volkov are applied to a unidimensional Constant Flux Layer model using the similarity theory. The results show the Volkov formulation reducing the surface wind in about 30% in the presence waves with of peak period between 5 and 12 seconds..</abstract>
