Abstract:

This thesis aims at elucidating the effects of urban surface-urban boundary layer-mesoscale flows interactions on the surface energy balance and turbulent exchange in the urban boundary layer (UBL). At first, the role of urban surface-atmosphere interactions on the quantification of the surface energy balance over urban areas in urban canopy models (UCMs) is studied. Then, I investigate how uncertainties in the external atmospheric forcing and surface parameters can affect the surface energy balance and thus the coupling between the urban surface and overlying UBL. Finally, an analysis on the interactions between the urban surface and the low-level jet is studied to investigate their effect on the turbulent exchange in the urban boundary layer and the low-level jet characteristics.
