DEMANDS FOR MODELLING BY FORECASTING OZONE CONCENTRATION IN WESTERN SLOVENIA

摘要

The highest ozone concentrations in Slovenia occur in the southwest part of the country. This region has Mediterranean climate with a lot of sunshine during spring and summer. Ozone precursor emission in the western part of Slovenia is moderate. The main source of ozone precursor emission is traffic, emissions from other sources are small. Those emissions appear in the relatively narrow zone along the coast and the border with Italy. The area around the central part of the country is sparsely inhabited. The terrain there is rather hilly reaching 1500 m altitude. As opposed to this region, the emission of pollutants in the Po valley west from Gorica county is very high. This is one of the most industrialized regions in Europe. During the summer several episodes of photochemical smog are reported from big cities of North Italy where measures to abate pollution are introduced in case of such situations. Transport of pollutants across the border can be registered in the neighbouring countries. The main reason for the exceedances of the information threshold in the western part of Slovenia is the transport of pollutants. We have available good prediction of meteorological parameters in that area. To fulfil all demands of legislation regarding ozone concentration prediction, proper models should be chosen and adapted to these circumstances. More extensive monitoring will be performed for the validation of the models.
