Evaluation of planetary boundary layer parameterizations with the WRF model in the Metropolitan Region of Salvador.

Abstract

Evaluation of the parameterization of the PBL Planetary Boundary Layer in the Metropolitan Region of Salvador using the Weather Research and Forecasting (WRF) model. The performance of numerical simulations was evaluated using radiosonde data. The physical parameterizations used in the model showed good agreement for temporal comparisons of vertical and horizontal wind speeds and wind directions predicted by the WRF model. The main objective of this initial study is to evaluate the performance of the physical parameterization of the model for the behavior in the PBL. The proposed initial study shows good agreement between the simulated and measured data, but the evaluation of the PBL for the period does not suggest a characterization of the Internal Boundary Layer.
