Abstract

Efficient high resolution methods for air pollution models A. Tomlin, J.M. Ware, J. Smith, M. Berzins, M.J. Pilling Department of Fuel and Energy, School of Computer Studies and School of Chemistry, University of Leeds, Leeds LS2 9JT, UK This paper investigates the use of time dependent adaptive gridding tech- niques tor the solution of atmospheric reaction/flow problems. Preliminary 2D studies related to the effects of power station emissions on regional ozone levels have been carried out. The results show the importance of using adap- tive grids in order to represent the interaction of the plume with background air over large distances. The adaptive mesh automatically reveals features of cross wind concentration profiles which would not be shown using the stan- dard mesh sizes adopted in regional atmospheric calculations. As the level of adaptivity increases, and the mesh becomes locally refined in regions of steep spatial gradients, the total and peak ozone concentrations c
