Rogue Waves, Unexpected Waves, Wave Trends

Johannes Gemmrich

Occurrence rates of rogue waves

Exceedance probability P of normalized crest height (top) and normalized wave heights (bottom) for a simulated wave field corresponding to a JONSWAP spectrum with forth order Stokes correction. A standard Weibull distribution would result in strait lines. The curvature of the line implies a higher occurrence rate of extreme wave and crest heights than predicted by the standard model, depending on the initial wave steepness R (see Gemmrich & Garrett 2012, NHESS.)
