This article concerns the calculation of the wave period probability densities in non-Gaussian mixed sea states.The calculations are carried out by incorporating a second order nonlinear wave model into an asymptotic analysis method which is a novel approach to the calculation of wave period probability densities.Since all of the calculations are performed in the probability domain,the approach avoids long time-domain simulations.The accuracy and efficiency of the asymptotic analysis method for calculating the wave period probability densities are validated by comparing the results predicted using the method with those predicted by using the Monte-Carlo simulation(MCS) method.
