Abstract: In a two-layer model with a rigid surface and a flat bottom on an f-plane, an internal Kelvin wave is forced by quasi-geostrophic, mesoscale meanders of a coastal current. These meanders are assumed to be quasi-periodic along the coast, forming a cluster with an alongshore length 1/Ro times as long as the meander scale, where Ro is a small Rossby number (Ro?1). The Kelvin wave solution has a form in which the pressure on the coast has a small (?Ro) alongshore gradient with an ?1 amplitude variation over many meander length scales. It is suggested that the boundary condition for a coastal current should satisfy the balance between the (ageostrophic) pressure gradient and the acceleration.
