The validation with data shows that the fully coupled model (C4, panell upper right on the figure below) bette represents the 'strange' sea level behavio observed between 1993 and 1998 in the Eastern Mediterranean. Probably due to the cooncomitant Eastern Mediterranean Transient, the sea level in the 90's in the EM shown a complicate behavior with apparent oscillation of the sea level height both in space and time.
Figure. Sea level trend observed between 1993 and 1998 in the EM from AVISO data (upper left panel) fully copled experiment (upper right panel), oceanic stand-alone experiment (lower left panel) and partly coupled experiment (lower right panel, this experiment is equal to C4 except the interactive river run off scheme)
Land-surface atmosphere interaction
We investigate the impact of land cover changes on regional climate over the Euro Mediterranean area. Land use and Land Cover Changes (LCC) affect the local, regional and global climate system through biogeophysical and biogeochemical processes that modify both surface-atmosphere exchanges of momentum, energy and greenhouse gases and surface roughness.
The feedback mechanisms between the land surface and the atmosphere have been increasingly investigated during last decade due to the increasing computational power. Therefore, in order to study the potential impacts of LCC on local climate, the simulations performed by General Circulation Models (GCMs) have been complemented by the use of Regional Climate Models (RCMs): in fact, the coarse resolution of the GCMs limits their capability to capture mesoscale features that play a pivotal role in regional dynamics.
