Some aspects of the structure of the stratified atmospheric boundary layer of N-E Brazil

The preliminary results of an analysis based on the experiment "Experimento de Microfisica do Nuvens-EmfiN" (Experiment of Microphysics of Clouds), conducted by Universidade Estadual de Ceara-UECE at Fortaleza (3.77 S and 38.60 W), a semi-arid tropical region of N-E Brazil, are presented. The kinematic stresses are computed by the layer integration of the Planetary Boundary Layer (PBL) momentum equation for horizontally homogeneous turbulence above the viscous sublayer condition and considering that the inertial acceleration terms could be neglected compared to the Coriolis force and pressure gradient force. The computed stress profiles are in good agreement with the results reported in the literature.
