WebJan 1, 2024 · In addition to estimating the mesoscale lateral eddy diffusivity, studies also characterised eddy stirring at scales smaller than the dominant eddy scales (∼100 km). … WebDec 5, 2013 · We investigate and quantify stirring due to chaotic advection within a steady, three-dimensional, Ekman-driven, rotating cylinder flow. The flow field has vertical overturning and horizontal swirling motion, and is an …
WebFeb 4, 2024 · Based on the composite eddy, following ref. 8, we define the mean stirring (F stir) and trapping (F trap) components of the meridional eddy heat flux across an unit length at a certain depth z as WebUsing this, the mixed layer lateral eddy diffusivities associated with (i) eddy stirring and small-scale mixing and (ii) surface damping by air–sea interaction is quantified. In the ACC, a diffusivity associated with surface damping of a comparable magnitude to that associated with eddy stirring (500 m 2 s −1) is found.
WebSep 13, 2024 · They found a dipole feature was created around eddy periphery, and eddy stirring was stronger at the leading side than the trailing side. Off the coast of Chile, the zonal gradient of chlorophyll is much stronger than the meridional gradient ( Fig 1A ), and the eddies mostly propagate westward against the direction of chlorophyll gradient ( Fig ... WebLateral stirring is a basic oceanographic phenomenon affecting the distribution of physical, chemical, and biological fields. Eddy stirring at scales on the order of 100 km (the …
