| Zusammenfassung |
| The
Mediterranean basin is located at the crossroads of air masses carrying
gas phase species such as ozone and precursors, as well as natural and
anthropogenic aerosol particles. These species contributes to regional
pollution and can have strong effects on the regional radiative budget
with ensuing impact on regional climate fluctuations from daily to
multidecadal time scales, as well as on ecosystems and air quality over
the Mediterranean basin. Aerosol linked processes still represent one
of the main sources of uncertainty in past climate change attribution
and future climate change projections notably due to high spatial and
temporal variability. The use of high-resolution RCMs therefore offers
an interesting potential for a better characterization of
aerosol-radiations and climate interactions in the complex Mediterranean
region. In the context of Med-CORDEX and MISTRALS-ChArMEx programs, a
FPS (Flag Pilot Study) has been proposed with the aim of answering
important scientific questions such as:
- Can we fully characterize the Mediterranean aerosol past variability
and future evolution at climate scales ? in particular using RCMs.
- Can we understand the role of the Mediterranean aerosols on the past
regional climate variability ? including issues related to regional
climate change attribution and aerosols representation in climate
models (GCM, RCM).
-Can we determine the role of regionally-born aerosols in the
Mediterranean future climate sensitivity ? in particular using RCMs as
complementary approach to GCMs.
- What is the aerosol role in shaping the Mediterranean extreme events ?
(e.g. heat waves, heavy precipitation events).
The presentation will focus on the development of simulation strategies
involving several research groups, and will gives some preliminary
results as well as relevant information to join the initiative. |
