Open-access DETERMINAÇÃO DE PARÂMETROS DE RUGOSIDADE E RELAÇÕES ENTRE FLUXOS E GRADIENTES SOBRE FLORESTA

AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    Values of parameters which characterize forest rugosity for horizontal air flux are determined from wind velocity profiles over the vegetation, in atmospheric neutral conditions, ӘΘ/Ә z=Ο. These profiles are adjusted to the logarithmic profiles by numeric optimization procedure. Analyses over the connection between flux and gradients of wind velocity for other atmospheric conditions are also presented. Meteorological Informations of this work were obtained in the Amazon. Micrometeorologlcal Experimente, during September 1983 at Ducke Reserve, Manaus-AM.
