Analysis of winds and SO, concentrations in complex terrain P. Mlakar, M. Bofnar Jotef Stefan Institute, Jamova 39, SI-1000 Ljubljana, Slovenia ABSTRACT The Kohonen neural network and Leaders' method were used for cluster analysis of ground level winds in the basin around the Sostanj Thermal Power Plant. Furthermore, the dependence of ambient SC>2 concentrations on the clusters obtained was analysed. The results prove that the cluster analysis proposed can be a very effective tool for compressing a huge wind data base in order to find correlation between winds and pollutant concentrations. INTRODUCTION Slovenia is a small country located on the sunny side of the Alps. Many industrial plants are located in the valleys and basins. SO2 pollution from tall stacks of large coal fired Thermal Power Plants is one of the greatest environmental problems. A typical example is the Sostanj region where the biggest thermal power
