| Zusammenfassung |
| Here, we describe our use of the Lagrangian 3-D FLEXPART model to
investigate the variation in sources of moisture related to the drier and
wetter conditions of the different regions that surround the Mediterranean
Basin. We carried out seasonal analyses for the period from March 2000 to
February 2005, and identified those years with the highest and lowest rates
of precipitation by season, averaged over eight different continental
regions. The variation in specific humidity along the 10-day backward
trajectories of the particles identified over the target areas was tracked
for the selected period, and the characteristics of the moisture sources
were then compared between wetter and drier conditions by season. Although
they only represented a relatively short period, the results suggest that in
most of the years chosen, the moisture sources were more extensive and/or
more intense during wetter periods. The contribution of the north Atlantic
as a source of moisture is apparent for the Iberian Peninsula, for France
and for Central North Africa. Otherwise, the Mediterranean Sea is the
predominant source for Eastern North Africa, and for the Italian and Balkan
Peninsulas. Local sources provide moisture for the Eastern Mediterranean and
Western North Africa. |
