The Influence Of The Earth's Rotation On Surface Waves

Considering the earth's rotation included in the governing equations of the inviscid,imcompressible fluids, the harmonic wave solutions and dispersion relations of the linear and nonlinear surface waves are obtained by using the perturbation method. The results show that the phase de-layed factor einz which is increased with the depth is added on the every wave speeds compare with the traditional approximation (only the vertical component of the earth's rotation is included in the governing equations). Moreover, the wave pressure is increased by the horizonal component of the earth's rotation, physical meaning of which is that the horizonal component of the earth's rotation react on seawater admixture.
