An inhomogeneous Benjamin-Davis-Ono-Burgers (BDO-Burgers) equation including underlying surface, slowly changing underlying surface and turbulent dissipation is derived in terms of quasi-geostrophic vorticity equation by employing the singular perturbation method. An inhomogeneous BDO-Burgers equation describing the evolution of the amplitude of solitary Rossby waves is investigated.
