| Zusammenfassung |
| Considering the Mediterranean as a region of high evaporation and low
precipitation, evaluations of sinks and sources of moisture and precipitation
in the Mediterranean basin have been carried out within the frame of the
CIRCE (Climate Change and Impact Research: the Mediterranean Environment)
project. Besides these evaluations, residence time and stagnation/ventilation
analyses have been carried out to investigate transport to and from the
Mediterranean basin and in the basin itself. A Lagrangian moisture diagnosis
method calculating budgets of evaporation minus precipitation was applied to
a 5.5 year (October 1999–April 2005) trajectory data set and evaluated for
eight representative Mediterranean Regions Of Interest (ROI). The
Mediterranean basin has been identified as a major source of moisture and
precipitation to the surrounding land area and to the basin itself. Main
regions of stagnation, i.e. the Po basin, have been defined on a seasonal
basis through residence time analysis. Evaluation of the transport to and
from the basin shows that the Mediterranean is a crossroad of airstreams
where air enters mainly from the northwest and continues in two separate
streams, one going southwest over North Africa into the trade wind zone and
the other one to the northeast through Central Asia. |
