Abstract

The use of an interpolation numerical wind model for regional air pollution dispersion studies. A case of study V. Espert, J. Catala, J. Camarasa, P. Iglesias Department of Hydraulic Engineering and Environment, Polytechnical University of Valencia, Ap. de Correos 22012, 46080 Valencia, Spain ABSTRACT We have elaborated an interpolation numerical wind model to be used as input data in regional air pollution dispersion studies. This model evaluates the principal components for the wind observations and the wind patterns for the grid nodes in a complex terrain by solving a partial differencial equation applying the Finite Element Method. The wind field for every measurement time is obtained as a linear combination of the wind patterns, with coefficients evaluated by means of the simultaneous observations and the principal components. This is part of a study to evaluate the dispersion capacity of air pollution in the Comunidad Valenciana (Spain) rela
