INFLUENCE OF THREE DIFFERENT WIND FIELD INITIALIZATIONS IN CALMET MODEL ON DISPERSION MODELLING IN COMPLEX TERRAIN

In the present study we focus on evaluation of results from CALPUFF modelling system around Sostanj thermal power plant (TPP) in northern Slovenia. Sostanj TPP presents a significant emission source located in a very complex terrain where local scale dispersion modelling is extremely challenging due to meteorological conditions characterized by weak winds, mesoscale circulations (weak up- and down-slope winds, valley channelled winds) and strong temperature inversions. Consequently, in our study we decided to focus on the influence of different wind field initializationstrategies on modelling results.
