Abstract:

This work evaluates the performance of four turbulence parameterization schemes available in the BRAMS model during the simulation of a Squall Line occurrence in the Metropolitan Area of S o Paulo, Brazil, with the goal to select the parameterization that possible works better for this kind of phenomena. Simulation results were compared to infrared satellite images provided by GOES and to precipitation estimates from TRMM. Through the analysis of some meteorological fields and by using some statistical parameters such as BIAS and MSE, the anisotropic deformation scheme, based on Smagorinsky (1963) horizontal diffusion coefficients and its one-dimensional analog for the vertical coefficients, was considered the best scheme for the simulated case.
