¿Cómo impacta la estructura vertical de la atmósfera y las heterogeneidades superficiales en el desarrollo y características de las brisas costeras y de montaña? El proyecto WINDABL

Abstract

Some modelling experiments have shown how the vertical structure of the atmospheric boundary layer is a key factor that controls the breeze characteristics at the surface. This issue motivated the development of the WINDABL project* to further investigate this finding through an observational and modelling strategy. We present the methodology carried out for the observational part of the project, which consisted of the installation of meteorological (and surface energy balance) stations at strategic locations for the long-term monitoring of breezes and the launching of atmospheric soundings during intensive observation periods characterised by breeze conditions. This strategy was developed both at a coastal (Gulf of Cádiz) and a mountainous (Pyrenees) area. We also present some first results obtained from the analysis of the data of the different towers and from 26 radio soundings launched during 8 different breeze events that allow to highlight the breezes characteristics during contrasting background winds and different ABL thermodynamic vertical structure at both locations.
