Non-linear dynamics of wave-groups in random seas: Unexpected walls of water in the open ocean

Abstract:

This paper investigates the size and structure of large waves on the open ocean. We investigate how non-linear physics modifies waves relative to those predicted by a linear model. We run linear random simulations and extract extreme waves and the surrounding sea state. For each extreme event we propagate the waves back in time under linear evolution before propagating the wave-field forward using a non-linear model. The differences between large linear and non-linear wave-groups are then exa...
