Statistics of Extreme Waves in Random Media — •Jakob Metzger1,2, Ragnar Fleischmann1, and Theo Geisel1,2 — 1Max-Planck-Institut für Dynamik und Selbstorganisation, Göttingen, Deutschland — 2Institut für Nichtlineare Dynamik, Universität Göttingen, Deutschland
Waves traveling through random media exhibit random focusing that leads to extremely high wave intensities even in the absence of nonlinearities. Although such extreme events are present in a wide variety of physical systems and the statistics of the highest waves is important for their analysis and forecast, it remains poorly understood in particular in the regime where the waves are highest. We suggest a new approach that greatly simplifies the mathematical analysis and calculate the scaling and the distribution of the highest waves valid for a wide range of parameters [1].
