Figure 1 (corrected). Numerical solution of the averaged equations for the source–sink vortex. (a) The assumed azimuthal velocity v0, (b) the radial velocity u0, (c) the vertical velocity w0, and (d) the boundary layer thickness δ all computed at a central Rossby number of 1. The solid curves show the linear theory, the dashed curves the result obtained with the self-similar profile, and the dotted curves the result obtained with the non-self-similar profile. In (b) the solid and the dotted curves are identical by assumption and thus only the solid curve is shown.
