FORECASTING AND DIAGNOSTIC-ANALYSIS OF PLUME TRANSPORT AROUND A POWER-PLANT

A nonreactive Lagrangian atmospheric diffusion model is used for the s imulation of SO2 concentration around the As Pontes 1400-MW power plan t located in northwestern Spain. This diffusion model has two kinds of input: 1) diagnostic wind fields from real measurements and 2) foreca st wind fields from a 24-h mesoscale prediction. This model-based syst em is applied for a particular day around the As Pontes 1400-MW power plant, which is a coal-fired power plant. The shape of estimated and f orecast plumes are compared, and the meteorological prediction results are analyzed.
