WRF wind forecasts from fouroperative schemes used by OHMC (Observatorio HidroMeteorológico de Córdoba), atest scheme (WRF-E) and two daily runs with 4 km horizontal resolution wereanalyzed. Wind simulations were compared with measurements from eight groundstations with anemometers at 10 m high during the period from June, 2019 toJune, 2020. WRF-E incorporates more vertical levels, and an activated topo_windoption. The wind speed results show that WRF overestimates wind speed at moststations and the WRF-E model reduces the BIAS and the RMSE when compared withthe operational models. The wind direction analysis shows that the higher thewind speed is, the more accurate the models are. In addition, a wind gustforecasting has been implemented and evaluated in this work. Wind gustcorrelation coefficient values are between 0.3 and 0.6, RMSE is between 3 and 5m/s, and a positive BIAS (<2 m/s) at most stations.
