Evaluation of Microphysical Parameterizations of the WRF Model in a Tropical Region

Abstract

The performance evaluation of the Weather Research and Forecasting (WRF) model was carried out using eight microphysics schemes in order to identify the best parameters for the most and least rainy periods. The modeling results were compared with the observational data from a tower located in the municipality of Esplanada, in the state of Bahia, with anemometers at heights of 80, 100, 120 and 150 m. In general, it was found that all tested schemes can be used in tropical regions, however, it can be concluded that Eta and Kessler showed better performances for the more and less rainy period, respectively, in addition to overestimating the speed.
