Coastal Air Pollution Meteorology and Meteorological Models

The role of orography in a complex area is of great importance, even more so
when the study area comprises a coastal region where there is a critical need for
topographical information due to the presence of the sea (or, in general, large water
masses). The surface boundary condition is generally defined by means of a Digital
Elevation Model (DEM), which provides information about terrain heights in the area
of interest. Both DEM and computational domains are discrete representations of
reality, and need algorithms capable of translating the continuous reality into a discrete
model. This study illustrates the care that must be taken when defining the surface
boundary condition in order to avoid significant misinterpretation.
