Abstract

The aim of this contract is the characterization, from the thermal and anemological point of view, of the lower layers of the atmosphere at a coastal site, affected by breeze circulation. Data are utilized to set up diffusion models for accidental releases of airborne materials, both of short and prolonged duration. Five inland meteorological campaigns, lasting one month each were carried between January 1982 and January 1983; 2 campaigns in the open sea (April, July 1983) followed. The analysis of the data collected showed the development of a well defined IBL during onshore flow only in Spring and Summer, while an inversion layer was detectable aloft independently of the season (in anticyclonic situations). A simple diffusion model was developed for short duration releases at a local scale. Finally, the analysis and elaboration of the data, collected on site allowed the extension of the model to prolonged releases.
