Abstract
Interactions between different spatial and temporal scales play a major role in determining the flow structure over the urban canopy in densely built agglomerations. The intense surface in-homogeneities result in the generation of additional terms in the turbulent transport within the urban atmospheric boundary layer (ABL), which in effect generate equally intense temporal in-homogeneities. Aiming to address the limitations which arise as a result of physical disparities between the scales involved, a novel two-way scheme has been developed within the frame of the EU MEGAPOLI project to couple the mesoscale model MEMO and the microscale model MIMO, utilising a collection of interpolating metamodels. The methodology developed was employed for assessing the effects of multiscale interactions on turbulent transport in the city of Paris using the MARS-aero model, and was validated based on comparisons with monitoring measurements. Simulation results reveal an improvement of the prediction skill over non-coupled models in accurately resolving scale interactions on the atmospheric flow within the urban ABL.
