Topographic beta effect

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.

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.
