Mesoscale Modeling of Atmospheric Conditions during severe SO2 Episode in Rijeka, Croatia

A severe pollution episode occurred in Rijeka, Croatia during 3-5 February 2002, where a daily mean SO2 concentration reached even 225.5 μ g m-3. A previous study of the above episode suggested the fumigation due to the weak synoptic circulation and high-pressure conditions. Rijeka is a coastal industrial town surrounded by mountains, located at the Northern Adriatic, at a position where the sea has made its deepest incision into the European continent. Thus, it exibits very complex wind regime, which can affect the air quality. The aim of this study is to investigate mesoscale atmospheric conditions, and particularly airflow and turbulence within the lower troposphere during above severe pollution episode. The results were produced using 3-D, higher-order turbulence closure model and will help in the future rational design of integrated emissions control strategies for the greater Rijeka area.
