A novel numerical simulation procedure has been proposed for prediction of local urban climatological phenomena. Buildings and skyscrapers in the urban area were modeled as a collection of porous blocks of prescribed permeability and porosity. A new set of the governing equations based on the volume averaging theory has been derived in which the velocity vector, Exner function, potential temperature and the mass fraction of water are dependant variables. A numerical integration scheme similar to SIMPLE has been developed to solve the set of the equations. Sample calculation results reveal interesting climatological phenomena, associated with the local urban climate.
