dc.description.abstractThe PYREX prograrn is a major field study of the dynamical influence of the Pyrénées mountains (on the border between France and Spain) on the atmospheric circulation. In October and Novernber 1990 a large number of experimental rneans had been deployed in the area, including additional sounding systems, automated stations at high elevation sites wind profilers, sodars, constant level balloons, and four research airplanes. The rnain focus was on the quantification of the retardation of the cross-mountain flow by the range, but a number of related rnesoscale phenornena had been captured, e.g. the forrnation of lee waves, lee eddies, sheltering areas, and local surface winds. The data interpretation was supported by an extensive effort in rneso-scale numerical rnodelling, and it is argued that only numerical models conveniently qualified by observations, can docurnent the momentum budget in a consistent way. Irnprovernents in the field of mountain waves and rnountain roughness representation in the large-scale atrnospheric rnodels are expected from the PYREX results as well as improvernents in the performance of meso: scale models for the operational forecasts. The present paper presents a broad introduction to the experiment. It reviews the experimental set-up and the available data sets. Finally, two more specific topics are discussed in depth, as examples of the available data and modelling strategy: the lee wave event of 15 October 1990 is presented with both experimental and model results. Sorne of the findings concerning the Tramontana wind are also discussed.es_ES
