WebMar 1, 1997 · In other words, the topographic beta-effect plays a major role of reducing the Kuroshio transport predicted by the Sverdrup theory in winter. As demonstrated by Sakamoto and Yamagata (1996) using a simple planetary geostrophic model with a continental slope, the baroclinic flow is excited not only by the strong winds in winter but … WebWhereas the LC may depend primarily on planetary beta once freed from topography, the Gulf is enclosed by steep escarpments that are also known to be important (Hurlburt and Thompson, 1980). These escarpments result in a topographic beta effect that may exceed the planetary beta effect by an order of magnitude along the escarpments.
Energetic Topographic Rossby Waves in the Northern South China …
WebThis is just the barotropic Rossby wave influenced by topography. If β t is large, the second term in the numerator dominates and we have topographic Rossby waves. Generally, if depth increases poleward, β t is positive and the topographic beta effect reinforces the regular beta. If it is negative, it overrides and can even cause eastward ... WebApr 21, 2024 · Large-scale topographic manipulation carried out at one site a decade after initial restoration successfully increased topographic heterogeneity and increased beta diversity when surveyed 3 years after manipulation.

In particular, the topographic beta effects indicate that the across-scalp reduction arose from focal reductions rather than global changes. WebAug 10, 2024 · A topographic $\beta$-effect is naturally present because of the curvature of the free surface. Instantaneous turbulent zonal jets spontaneously emerge from the small-scale forcing, equilibrate at large scale, and can contain up to 70% of the total kinetic energy of the flow once in a quasi-steady state. We show that the spectral properties of ... tercet in poetry
