There is always distinguishing density-stratified feature in the ocean's surface layer, and mostly, the waves on the ocean surface are irregular. In this study, based on Reynolds Averaged Navier-Stokes(RANS) equations and irregular wave theories coupled with Airy and Stokes theories, the waves' characters on the ocean surface are studied theoretically and numerically. The volume of fluid (VOF) method coupled with the Airy and Stokes wave theories has been used to determine the free surface effect of water. The density stratification of the water is set by patching the upper and lower ocean zone separately and the water density varies to the temperature linearly. The coupled irregular waves' characters are in the density-stratified ocean are investigated numerically. This method could provide important reference for the study of ships' motion, waves and hydrodynamics.
