Spatial dependence of extreme seas in the North East Atlantic from satellite altimeter measurements
Abstract The extremal spatial dependence of significant wave height in the North East Atlantic is explored using Joint Altimetry Satellite Oceanography Network satellite altimeter observations for the period 2002–2018, and a spatial conditional extremes model motivated by the work of Heffernan and T...
