Implication of meridional barotropic flows over topography by tracking eddy propagation. Vectors denote eddy propagation velocity derived by tracking eddies retrieved from satellite SSH53 (see Methods). Color scale indicates the meridional propagation speed, where red (blue) denotes northward (southward). Characteristics \(Q_{\rm c} = \beta y + \frac{{\psi _{{\rm T a}}}}{{R_{\rm d}^2}}\), as well as analyses of eddy propagation from satellite SSH34, imply that meridional propagation of eddies may be caused by ambient barotropic flows. Contours denote Qc (contour interval 0.5 × 10−6 s−1) with thick lines of 4.5 (solid black), 5.0 (dashed black), 8.0 (dashed blue), and 12.0 (solid blue) × 10−6 s−1. Topographic rises A, A′, and B are indicated
