ecological impacts and concludes this paper. 2. Study area and data 2.1. Description of the study area The study area, hereafter called the Mediterranean central area (MCA), is located between 30°–45°N, 8°–20°E ( Figure 2 , large square box). The area of interest is approximately centered over the Tyrrhenian Sea, between the western coast of the Italian mainland and the northern coast of Sicily. Westward, the area is delimited by southeastern France and northeastern Algeria. The

are expected to affect hydropower generation. Climate change will most likely increase the frequency of droughts and water scarcity in some areas, such as southern and southeastern parts of Europe, which already suffer water stress ( Bernstein et al. 2007 ). Particularly interesting, as important indicators of global warming, are the projected trends of climate variables such as temperature and rainfall on the Mediterranean area. In this region, according to Christensen et al. ( Christensen et al

1. Introduction The western Mediterranean Sea region is regularly affected by heavily precipitating events (HPEs) potentially associated with devastating flash floods (e.g., Sénési et al. 1996 ; Romero et al. 2000 ; Ferretti et al. 2000 ; Argence et al. 2008 ). Among other areas (eastern Spain, Italy, and northern Africa), southern France is particularly exposed to this hydrometeorological hazard.

farther east; the last area affected by the precipitation is the north-facing slopes of the Pre-Betico Mountains, that is, the wet nucleus south of Valencia. The precipitation in this case tends to be much more generalized and long-lasting than in the situation discussed in section 4c ; it also tends to affect the whole region. Modeling of these processes ( Pastor et al. 2001 ) indicates that most of the moisture required to drive the precipitation is evaporated from the Mediterranean, and thus the

calculated over large (300 km) grid boxes. Second, use them to evaluate cloud properties simulated by a GCM at a regional scale. The method allows for the estimation of to what extent the defect of the global model affects a particular area—the southern European Mediterranean Sea area, which is poorly studied in terms of climate models. We consider the southern Europe Mediterranean area here (28°–50°N, 15°W–40°E): the particular land–sea distribution of the region and its rich topography are likely to

the framework of the Meteorological Applications of GPS Integrated Column Water Vapor Measurements in the Western Mediterranean (MAGIC) project ( Haase et al. 2001 ), GPS zenith tropospheric delays have been, since January 1999, routinely delivered and monitored at the Centro di Geodesia Spaziale of the Italian Space Agency (ASI) in Matera, for a network covering the central Mediterranean area. The network has a higher resolution over the Italian territory due to the fact that all the available

demanding in basins like the Mediterranean Sea, where coastlines are mostly surrounded by mountain ranges that strongly affect the local wind circulation ( Zecchetto and Cappa 2001 ; Lavagnini et al. 2006 ). In fact, under particular weather conditions, surrounding orography can funnel wind flows with wind speeds that can reach gale strengths. Figure 1 schematically shows the geography of the Mediterranean area, together with the main local winds. The numerical description of surface winds in such

heterogeneity of the land cover, burned areas are generally small. Analysis of the official reports [European Forest Fire Information System (EFFIS)] compiled for five Mediterranean countries (Portugal, Spain, France, Italy, and Greece) during a 30-yr period indicates an average fire size of 10 ha with a minimum of 6 ha for Portugal and France, a maximum of 30 ha for Greece, and a value of 11 ha for Spain and Italy ( Camia et al. 2009 ). In Italy, fires get particularly intense in the southern regions of

-Cantos and Azorin-Molina 2004 ), bringing an average of 100–125 mm yearly to inland areas ( Millán et al. 2005 ). Most air boundaries that cause storm development are primarily associated with the sea breeze, since they are the main mesoscale circulation in terms of occurrence and persistence over the region. Consequently, sea-breeze fronts are common phenomena from May to October in the Iberian Mediterranean area and the isle of Mallorca (Spain; Fig. 1a ). Despite their importance for local weather and

Introduction The aim of the current study is to investigate computationally the evolution and transport of pollutants over a Mediterranean coastal area subject to pronounced thermal wind systems. Furthermore, the influence of the biogenic volatile organic compound (BVOC) emissions in relation to the anthropogenic volatile organic compound (AVOC) emissions on the amount of photochemical pollutants is examined. The area of interest is located on the Spanish east coast. This region experiences
