The relation between rogue wave occurrence statistics and properties of the directional and unidirectional wind-wave spectrum, described by the JONSWAP spectrum, are investigated. The free surface statistics are obtained from phase-resolving simulations. The stochastic approach to rogue wave occurrence is conducted based on the quantitative indicator parameters, which are designed to represent instabilities in wave-trains. Numerical findings are compared with measurements. Further, extreme value analysis (EVA) has been applied to indicator parameters based on 40 years of global wave hindcast data.
