Abstract

Importance of local meteorology in coastal ozone dynamics: a case study R. Cocci Grifoni, L. Magnaterra, G. Passerini & S. Tascini Dipartimento di Energetics Universitir Politecnica delle Marche, Italy Abstract Ozone dynamics are strictly dependent to meteorological conditions. Solar radiation, pressure distribution and horizontal wind field, along with precursor concentrations, play fundamental roles in ozone formation and depletion. The present case study concerns Falconara, an Italian town located on the Adriatic sea, which presents several air pollution modelling issues: complex orography, location at the mouth of Esino river and the presence of several distributed and point precursor sources. During the summer 2000 strong ozone episodes have been recorded in disagreement with other typical pollution concentration levels. The aim of our work was to investigating the role played by meteorological scenarios that may favour ozone formation, stagnation and recirculation. For this purpose RAMS
