... Longuet– Higgins in [32, 33]. In this theory the flow is periodic in the alongshore direction and, most importantly, the incoming wave forms a slowly varying wavetrain with constant amplitude in the alongshore ... [8]. Crucially, the Bretherton flow points backward, i.e. in the negative x-direction, at the vortex location above the wavetrain. Therefore the Bretherton...

... Lamb–Oseen vortex. In the frame rotating with the vortex core, the strain field rotates at the angular speed −ζ/2 and since the elliptic deformation is a mode m = 2, the fluid in the core of the vortex ... Neglecting the torsion, the obtained flow is therefore similar to the one studied previously. Indeed, the normal to the osculating plane (so-called binormal) is p...
