Abstract

We describe the model for excitation of ocean surface gravity waves by the wind blowing away from the shore. Numerical simulation shows that wave turbulence behaviour can be split in time into two different physical regimes: classical and non-classical one. The classical regime corresponds to self-similar solution developing for the characteristic times defined by ratio of the channel width to characteristic advection velocity of the wave field. The non-classical regime is happening later in time when the energy starts to reflect from the opposite boundary condition and corresponds to energy advection against the wind. It exhibits itself in waves generating predominantly parallel to the shore line, tending to slant toward the shore, as approaching to the beginning of the fetch, at 15 degrees.
