ABSTRACT The performance of a wind field diagnostic model (WIND-TERRAN) which deals with the topography in an explicit way is compared with the results of a conventional mass-consistent diagnostic model (KRISSY). The empirical scheme of WIND-TERRAN for treatment of topography is described. Models were run for six cases of rather strong wind flows over the Madrid basin. The adequacy of WIND-TERRAN for initializing more sophisticated diagnostic models are discussed. INTRODUCTION The pollutant concentration distribution estimated by dispersion models depends on (among others) the treatment of the wind field. Dispersion models usually include a wind field model to compute the distribution of the air flow over the region of study. Frequently, these models estimate the wind field from the observed
