| Zusammenfassung |
| The Dead Sea is a unique environment located in the Dead Sea Rift Valley. The fault system
of the Dead Sea Rift Valley marks the political borders between Israel, Jordan, and Palestine.
The Dead Sea region and the ambient Eastern Mediterranean coastal zone provide a natural
laboratory for studying atmospheric processes ranging from the smallest scale of cloud
processes to regional weather and climate. The virtual institute DESERVE is designed as a
cross-disciplinary and cooperative international project of the Helmholtz Centers KIT, GFZ,
and UFZ with well-established partners in Israel, Jordan and Palestine. One main focus of
one of the work packages is the role of aerosols in modifying clouds and precipitation and in
developing the Dead Sea haze layer as one of the most intriguing questions. The haze
influences visibility, solar radiation, and evaporation and may even affect economy and
health.
We applied the online coupled model system COSMO-ART, which is able to treat the
feedback processes between aerosol, radiation, and cloud formation, for a case
study above the Dead Sea and adjacent regions. Natural aerosol like mineral dust
and sea salt as well as anthropogenic primary and secondary aerosol is taken into
account.
Some of the observed features like the vertical double structure of the haze layer are
already covered by the simulation. We found that absorbing aerosol like mineral dust causes a
temperature increase in parts of the model domain. In other areas a decrease in
temperature due to cirrus clouds modified by elevated dust layers is simulated. |
