                         Centro Europeu ECMWF utilizados como dados de condi¸coes iniciais 
                         e de contorno para as simula¸coes de 48hs realizadas pelo BRAMS. A 
                         partir dos resultados obtidos pelas simula¸coes num´ericas, foram 
                         feitas compara¸coes entre os perfis de temperatura potencial dos

                         contributed for development of new eddy parameterization that 
                         describe the Planetary Boundary Layer (PBL) behavior. The 
                         objective of this work was to implement new parameterization of 
                         eddy diffusivity that refers to the stability conditions of the 
                         atmospheric (unstable, stable and neuter) in the Brazilian 
                         Regional Atmospheric Modeling System (BRAMS) numeric model. The 
                         classical statistical diffusion theory is used to esteem these 
                         diffusivities. This analysis, that was performed, were based in 
                         datas from WETAMC campaign of LBA project together with datas from 
                         the re-analysis of European Center ECMWF Model that were used as 
                         initial and boundary condition for simulation of 48 hours that 
                         were performed by BRAMS. From this obtained results, by numeric 
                         simulations, was performed comparisons among potential temperature 
                         profile of the observated datas with the simulated datas by the 
                         new parameterization and with Smagorinsky (1963) and Mellor and 
                         Yamada (1982) parameterization too. Further then computational 
                         gain in relation at number of necessary operations in each 
                         parameterizations, a new implementation showed satisfactory 
                         results when it was compared with the observated datas from forest 
                         farm (Rebio Jar´u) and pasture (ABRACOS).",
