Abstract

Characterization of wind fields at a regional scale calculated by means of a diagnostic model using multivariate techniques M.L. Sanchez, M.A. Garcia, A. Calle Laboratory of Atmospheric Pollution, Dpto ABSTRACT In the framework of an extensive programme on photochemical and acidifying regional transport sponsored by the Spanish CICYT Commission, a calculation of the wind fields using an algorithm of interpolation has been applied to the Region of Castile and Leon. Based on the observational data recorded at 10 surface meteorological stations from the I.N.M. in 1990, 158 daily wind fields at 12.00 G.M.T. were calculated in a 20*20 Km grid covering all the Region. In order to establish the prevailing transport of pollutants and to identify the influence of the topographical features under different synoptic situations, a relationship between wind fields and the regional weather patterns was perfomed using a multivariate clustering technique.
