description

Three-dimensional numerical models of the urban climate have been developed in order to simulate climatic changes and air pollution in urban regions due to anthropogenic activities. Two versions are presented. Model A covers mesoscale γ and uses the roughness length to characterize surface structure. The microscale version B approximates the actual urban build-up by rectangular blocks. Model A results agree reasonably well with observations. For complex building structures, the microscale model must be applied. Model B results on neutral flow and pollutant transport within a particular building configuration are discussed.
