摘要

The city of Lisbon is situated near the estuary of the river Tejo. The estuary separates the urban region west of the estuary from a more rural area in the eastern part. A new bridge will be built over the estuary modifying the traffic patterns of the region. As the city of Lisbon is built in a very complex region, the wind flow and the dispersion of pollutants are influenced by phenomena belonging to different mesoscale subscales. In view of the different scale influences, a nested grid technique is applied to simulate the wind flow and the dispersion of prospective traffic emissions over the Lisbon region. The simulation is performed using the EUMAC Zooming Model (EZM).
