WebBoundary and shear layers parallel to the axis of rotation in a rapidly rotating fluid are modified by inertial effects when the Rossby number R is not small enough to be neglected. If E is the Ekman number, inertial modifications to Stewartson E ¼ layers become important when the Rossby number is comparable with, or larger than, E ¼ and changes in the … WebDownload scientific diagram Schematic of the vorticity dynamics of the Ekman transport at a circular vortex forced by a uniform wind stress in the positive x direction (t, green vectors).

WebVortex in liquid collects particles in center. At xmas, I had a cup of tea with some debris at the bottom from the leaves. With less than an inch of tea left, I'd shake the cup to get a little vortex going, then stop shaking and watch it spin. At first, the particles were dispersed fairly evenly throughout the liquid, but as time went on (and ...
