Anomalies induced by mountains and sea in rainfall over land in the western mediterranean area

Objective



The western Mediterranean, a semi-enclosed basin bordered by large mountain ranges (Alps, Pyrenees, Atlas, etc.), is one of the regions on the Earth where meteorological events have a broad range of scales (cyclogenesis, strong winds, jet streaks, severe storms -sometimes with tornadoes-, torrential rain and flash floods, etc.).
It is well known that mountain ranges play a decisive key role in the genesis of these phenomena (in particular cyclogenesis and local winds). Also local triggering and focusing mechanisms can be due to orographic effects, as well as low level mesoscale forcing, which can themselves also be related to orography.
This latter forcing is normally the mechanism that triggers convection over the sea, which is at the same time the most difficult to study because of the non existence of continuous series of meteorological data over the sea. The aim of this project is to improve our basic knowledge of the meteorological processes that lead to the formation of storms and floods in the Mediterranean area.
Particular emphasis will be placed on the study of the scale interaction processes, where synoptic and mesoscale phenomena can play a synergistic role, in connection with oroqraphic forcing and air-sea energy exchanges, in the generation of severe weather events.
On the other hand, operational weather forecasts are not as good as desirable.
The answers to questions of where and why the models fail, are likely to be related to the misrepresentation of the scale interaction processes previously mentioned.
