Types de temps et risque d'inondation et d'érosion en Camargue : diagnostique et prévision au 21ème siècle (1993-2100)
2010
High sea surges and waves are the two mains hydro-meteorological phenomenon associated with coastal flooding and erosion in Camargue. For the period 1993-2002, high monthly frequencies of strong surges are usually associated with high frequency of strong waves. These two phenomenons mainly occur during weather type showing a deep low pressure system over the Bay of Biscay associated with high pressure over Central Europe. The monthly frequency of such weather regime indicates the probability of occurrence of high surges and waves along Camargue's coast. During the 21st century, the frequency of this specific weather regime could stay stationary for the A1b climate change scenario.
SURCOTES MARINES DANS LE GOLFE DU LION ET FORCAGES ATMOSPHERIQUES : VARIABILITE CONTEMPORAINE ET FUTURE (1950-2100)
2010
Sea surges in the Gulf of Lions are mainly forced by southerly and south-easterly winds. This regional-scale atmospheric circulation is leading by a strong zonal gradient between low pressure system over the Bay of Biscay and high pressure over central Europe. This synoptic-scale circulation mostly happens during “Greenland Above” weather regime. In the second half of the 20th century, a slow increase of the sea-level pressure over central Europe increased the probability of having “Greenland Above” weather types associated with a southerly atmospheric circulation in the Gulf of Lions, thus leading to strong surges. A linear regression is used to simulate the interannual variability of high…
