WebMar 27, 2024 · It is devoted to non-zonality. It is the joint effect of the influence of non-zonal shear flow and non-zonal bottom topography on Rossby waves propagation. The chosen study area is a branch of Kuroshio bending from a zonal direction on 55°. We estimate terms in dispersion relation compare them with the influence on the β-effect. WebDispersion in the isolated eddy is induced by planetary and topographic beta-effects, giving the eddy an asymmetric distribution. This asymmetric distribution allows for nonlinear self-advective propagation tendencies. These nonlinear tendencies play a key role in the direction of propagation of the eddy. Specifically, in a quiescient ...

WebTo investigate planetary and topographic beta effects on classical as well as unique features in the northern Canary Current system (NCCS), several numerical experiments using the Princeton Ocean Model are explored. To isolate the dependence of Coriolis parameterization (β-plane vs. f-plane) from the topographic beta effect, the first WebTopographic changes were also evident in all bands except for alpha, with reduced lateral frontal delta and posterior theta, and decreased posterior/increased frontal beta in the eyes-open condition. In particular, the topographic beta effects indicate that the across-scalp reduction arose from focal reductions rather than global changes.
