Regional and long-range transport scenarios for photo-oxidants on the Mediterranean basin in summer

Atmospheric research, begun in 1988, has shown that the dynamics of air pollutants in the Mediterranean basin in summer are governed by processes ranging from local to large meso-scale with diurnal cycles. Large scale convection over some regions, and up-slope winds in others, can inject aged pollutants into the Mid-troposphere, where they can participate in long-range processes within Southern and Central Europe. Two scenarios have been identified for the regional and long-range transport of photo-oxidants and other pollutants within, and out of, the Western Mediterranean basin. The first scenario involves the pollutants injected over the Spanish Central Plateau directly into the mid-troposphere, and the second, the reservoir layers created along the Mediterranean coast. In the second scenario the key components are: the semi-permanent high(er) pressure area over the colder waters in the Gulf of Lion-Western Mediterranean basin, the mountain ranges which surround it, and the coastal processes. During the day the coastal circulations renovate the upper reservoir layers while the lower ones are drawn inland with the sea-breeze, and effective flow is mostly perpendicular to the coast.
