Multi-site modelling and reconstruction of past extreme skew surges along the French Atlantic coast

ArXi:2505.00835v2 Announce Type: replace-cross Appropriate modelling of extreme skew surges is crucial, particularly for coastal risk management. Our study focuses on modelling extreme skew surges along the French Atlantic coast, with a particular emphasis on investigating the extremal dependence structure between stations. We employ the peak-over-threshold framework, where a multivariate extreme event is defined whenever at least one location records a large value, though not necessarily all stations simultaneously.
