Intercomparison on the Flow Field over the Attic Peninsula with Two Models
The circulation of air masses for the control of air pollution is particularly difficult to estimate in areas of complex terrain, due to the presence of mountains and hills or to the effect of large water basins. In the Athens area, the local circulation is mainly driven by the sea-land breezes, which are strongly influenced by a mountain ridge culminating at 1460m (Parnitha mountain fairly close to the sea-shore). Actual terrain slopes can be locally very large, which renders the simulation particularly challenging for mesoscale models. In this paper two different models participating in the APSIS intercomparison exercice are presented and initialized in order to describe the typical summer sea-breeze in the region of Athens.
