A MODELLING METHOD FOR ESTIMATING TRANSBOUNDARY AIR POLLUTION IN SOUTH-EASTERN EUROPE

A new methodology is presented for the model estimation of an import-export pollution balance across country borders based on the classification of the synoptic scale atmospheric circulation. As an application, the transboundary transport of SO2 and NOx across the Greek borders is investigated. Initially, the synoptic scale atmospheric circulation over Greece was typified on a daily basis using a database for a period of forty years employing an automatic classification scheme at the isobaric level of 850 hPa. According to the location of the anticyclonic and cyclonic centres, six anticyclonic and eight cyclonic types of circulation that predominate over Greece were distinguished. Subsequently, the transboundary transport to and from Greece was calculated by the aid of mathematical dispersion models for representative synoptic conditions in 1995. The annual total inflow-outflow fluxes were derived by weighing the model results with the annual relative frequency of the corresponding synoptic type appearance. The results of the new modelling method are similar to those following from the day-by-day calculation of the inflow-outflow fluxes for the whole year 1995 using the same models. The advantage, however, of the new methodology is that it is evidently less time consuming than the day-by-day calculations. Hence, the proposed methodology can be employed as a practical tool for several applications requiring the implementation of complex models over longer time periods.
