Analysis and validation of Weather Research and Forecasting model tendencies for meso-to-microscale modelling of the atmospheric boundary layer
Abstract
The different terms of momentum and energy budget simulated by the Weather Research and Forecasting model (WRF) are examined at two sites that depict diverse climate and orographic environments. The analysis focuses both on particular weather episodes of one-to-few days duration and in one-year statistics useful for the assessment of the annual wind climate of a particular location. In order to estimate their accuracy, a validation exercise is performed in the Cabauw Experimental Site for Atmospheric Research (CESAR) in the Netherlands, where a fair agreement is found when comparing the mean surface pressure gradient term extracted from WRF with the pressure-derived geostrophic winds observed by the CESAR project. This study is carried out under the New European Wind Atlas (NEWA) project as part of the effort to develop a model-chain system that connects mesoscale with microscale wind flow models with different fidelity ranges for wind resource assessment applications. Therefore the analysis deepens in the horizontal and vertical variability of the tendencies in each of the sites with the ultimate goal of providing some guidelines of their best usage as large-scale forcing of the microscale models.
