Atmospheric conditions of sea surges in the Gulf of Lions from 1900 to 2100
This PhD analyses variability of sea surges and extreme sea-level in the Gulf of Lion and its relationship with atmospheric conditions at different spatio-temporal scales from 1905 to 2100. Sea-level height time series at four stations (Port-Vendres, Sète, Grau-de-la-Dent and Marseille) are used, as...
