Nonlinear tides

Nonlinear tides refer to the complex behavior of ocean tides that cannot be adequately described by the linear superposition of tidal constituents. Traditional tidal models often rely on linear approximations, where the effects of different forces (like the gravitational pull of the Moon and the Sun) are summed linearly. However, in reality, tidal motion and the response of the ocean to these forces can exhibit nonlinear characteristics due to various factors.
