Ces tempêtes extrêmes que l'histoire ne nous a pas encore dévoilées

Abstract: RÉSUMÉ. -Les études d'aléa de submersion marine s'attachent à définir des valeurs extrêmes pour les niveaux marins et les houles et à combiner ces valeurs afin de produire un aléa de référence à la côte. Pourtant, ces phénomènes résultent souvent d'un même événement météorologique générateur : les tempêtes. Météo-France, le Cetmef et le Shom ont uni leurs efforts pour étudier les tempêtes menaçant le littoral breton et déterminer des événements extrêmes, dont on dédui-rait les paramètres hydrodynamiques pour l… Show more

“…Once validated, archives, coming from atmospheric re-analyses (ERA-Intérim, Meteo-France), tidal and water levels measurements (SHOM) and waves and coastal damage (CEREMA) were collected to strengthen and refine statistical laws for computing highest sea level occurrence periods (return period). From these archives, 137 events were analyzed and classified into a typology, consisting of 25 families of storms (Goutx et al, 2014). Each family was characterized by similar criteria as atmospheric storm trajectory, pressure gradient, concomitance with large tidal amplitude.…”

“…Moreover, estimates of sea level rise also inform studies of vertical land motion (Spada & Galassi, 2012). This is partly why detailed historical data stored in a collective database have a direct positive impact for research in several disciplines, including climate science, marine submersion (Goutx et al, 2014), geology and understanding of oceanic variability.…”
