In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object. Fluid behind the obstacle flows into the void creating a swirl of fluid on each edge of the obstacle, followed by a short reverse flow of fluid behind the obstacle flowing upstream, toward the back of the obstacle. This phenomenon is naturally observed behi… WebThe steep spiral arms (dip angle can be up to ∼4°) may be caused by eddy stirring. Seismic observations provide important insights into our understanding of the vertical structure of ocean eddies, the horizontal and vertical transport of matter, and fluxes of heat that can cause sea ice melting in the Arctic Ocean.
