A consistent linear theory is developed for determining the importance of boundary layer friction for thermally forced gravity and Rossby wave modes. Analytic case studies are developed on a mid-latitude β-plane in order to retain separability of the linearized equations in the presence of boundary layer friction in a slab mixed layer. It is found that frictional convergence is important in synoptic-scale Rossby waves (but not gravity waves). If the feedback between the boundary layer and the interior solution is not properly taken into account, however, it is found that the boundary layer convergence will be incorrectly evaluated and may be considerably overestimated.DOI: 10.1111/j.2153-3490.1977.tb00733.x
