“…The statistical method to reconstruct the surge levels is explained in detail in Cid et al (), which was in turn based on a similar approach used by Camus et al () to downscale multivariate wave climate. It consists of fitting a multivariate regression model between daily maximum surge levels (predictand) and the PCs of the daily SLP, GRDslp, and wind (predictor) where n is the number of PCs that achieved a statistical improvement of the results and are the coefficients obtained from the regression model.…”
