ABSTRACT Laboratory simulations of extreme random seas reveal that high wave

**crests**occur more frequently than predicted by ... in a non - Rayleigh distribution of wave**crest**and trough amplitudes based on the narrow - band assumption .Page 3

It was also found that the experimental probabilities of wave

It was also found that the experimental probabilities of wave

**crests**exceeding a given threshold were larger than those predicted by equation ( 9 ) . Several expressions for the probability density functions of nonlinear wave**crest**...Page 5

Thus , groups of high wave

Thus , groups of high wave
