An Atmospheric Diffusion Study on a Local Scale at a Coastal Site

SOME ATMOSPHERIC DISPERSION EXPERIMENTS WHICH WERE CARRIED OUT DURING SUMMER 1983 AND 1984 AT A COASTAL SITE OF MONTALTO DI CASTRO (ITALY) IN A SEA-BREEZE SITUATION ARE DESCRIBED. SULPHUR HEXAFLUORIDE (SF6) WAS USED AS ATMOSPHERIC TRACER, WHILE THE CHARACTERIZATION OF THE LOWER LAYERS OF THE ATMOSPHERE, FROM THE THERMAL AND ANEMOLOGICAL POINT OF VIEW, WAS PERFORMED BY VERTICAL SOUNDING WITH TETHERSONDE SYSTEMS AND PILOT BALLOONS. THE RESULTS OBTAINED HAVE BEEN ANALYZED IN ORDER TO OBTAIN INFORMATION ON THE SITE ATMOSPHERIC DISPERSION CHARACTERISTICS FOR A DIFFUSION MODEL ELABO- RATION. THE EFFECT OF THE STRONG DIRECTIONALITY OF BREEZE CIRCULATION DURING THE WARMEST PERIOD OF THE DAY AND THE LIMITATION IN VERTICAL DIFFUSION, CAUSED BY THE DEVELOPMENT OF THE INTERNAL BOUNDARY LAYER (I.B.L.) WERE CLEARLY EVIDENT
