The Application of a Stochastic Wind Model to the Meteorology of North West England
Many air pollution models utilise a wind speed given by a mean value over the time period under investigation [see e.g. discussions in references 1 and 2). This provides a valuable tool for many investigations since for successful utilisation of these models it is necessary to understand the individual effects (e.g. source strength atmospheric stratification and chimney height) before attempting to analyse the inter-relationships and feedbacks. Wind speed variation at surface type boundaries (e.g. land-sea) have been analysed by Jensen3 in terms of the surface roughness and these ideas have been utilised in an urban mixing layer model4 to predict the influence of surface roughness on plume trajectories5.
