DOI: 10.5194/nhess-2020-342
Abstract: Abstract. The occurrence of rogue waves is closely related to the non-Gaussianity of sea states, and the non-Gaussianity is sensitive to the combination of three spectral geometries: wave steepness, bandwidth, and directional spreading. This paper… read more here.
