| Zusammenfassung |
| An Eulerian study of the distribution over
the Island of Mallorca of a non-reactive pollutant (SO2) emitted from
an electric power plant operating at present on the north coast is performed
using a meso-β numerical model, paying particular attention to the
diffusive physical mechanisms. The study is applied to the conditions of
sea-land breeze development. This is a local circulation that dominates the flow
during the summer and favours transporting pollutants from the coast toward the
centre of the island. Results indicate that values of the ground-level
concentration higher than 5 μ g/m3 are restricted over a
limited and mountainous region during the whole diurnal cycle. However, when the
simulation is carried out with the inclusion of a twin electric plant which may
be built on the south coast, the affected area becomes larger, especially early
in the morning, when air over the island is sinking as a consequence of the land
breeze development. The inclusion of dry deposition in the simulations does not
produce important changes in the spatial and temporal evolution of the
ground-level concentration. |
