Calgary Downtown - Scenario 1:Time-averaged concentration at street level. Warmer colours indicate higher relative concentrations, with each colour level representing a factor of 10. Black arrows indicate wind direction at street level. Enlarge the figure.

Calgary Downtown - Scenario 1:Comparison of the CUDM simulation (left) and the same scenario modeled by MLCD, a non-urban model (right). The asymmetric deflection of the CUDM plume from the prevailing wind axis is in contrast to the symmetric plume of MLCD, which does not take into account the effect on the flow of buildings.
