Case Study in Jagua Bay at South of Cuba Using a Coupling WRF/CALMET

Abstract CALMET meteorological model was evaluated during a typical period of dry season in a coastal domain in the Jagua bay at the south of Cuba, for TERRAD parameter. Several resolutions and four different CALMET input datasets were used. The evaluation was focused in terms of model performance of wind and surface temperature issues. As input data, the WRF model results and meteorological measurements of different stations were combined. WRF model surface speed results has been significantly improved by CALMET model. A slightly improvement is obtained with resolution increasing. A high value of TERRAD of 80 km was obtained as the best fit for this parameter that matches with the domain size. The statistical results (both relative and absolute) were calculated on the stations that were not used as input data. Statistical relative values of wind speed were high, due to weak winds over the study period. However, the absolute ones were better. Significant improvement was also observed in wind speed and temperature for relative and absolute statistical values, when more stations as input data were provided.
