Code for Spatiotemporal variability and large-scale drivers of storm surge extremes on the northwestern European Shelf

This repository contains the Jupyter notebooks used to generate the analysis and figures in the Spatiotemporal variability and large-scale drivers of storm surge extremes on the northwestern European Shelf paper (10.1029/2025JC023795) including: A collection of Jupyter notebooks and analysis scripts for empirical orthogonal function (EOF) and Gaussian Mixture Modelling (GMM) analysis, surface pressure/wind stress composites, clustering experiments, and North Sea variability studies.
