Analysis of winds and SO_2 concentrations in complex terrain

摘要

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 SO_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.
