That is, the water within an eddy usually has different temperature and salinity characteristics to the water outside the eddy. There is a direct link between the water mass properties of an eddy and its rotation. Warm eddies rotate anti-cyclonically, while cold eddies rotate cyclonically.
Mode-water eddies have a complex density structure. Due to their shape, they cannot be distinguished from regular anticyclones in an eddy-centric (focused on the core of the eddy) analysis based on sea level height. Nonetheless, eddy pumping induced vertical motion in the euphotic zone of mode-water eddies is comparable to cyclones.
The nature of eddies are such that the center of the eddy, the outer swirling ring, and the surrounding waters are well stratified and maintain all of their distinctive physical, chemical, and biological properties throughout the eddy’s lifetime, before losing their distinctive characteristics at the end of the life of the cold core ring.

Rotating masses of water called eddies are common in the ocean. The newly revealed pairs, however, churn through the water up to ten times faster than their single counterparts, and are connected ...
Located between the eddy and the main current, the eddy line is a swirling seam of green and sometimes white water. Eddy lines vary in size based on the size of the water column, the gradient of the section, and the obstacle creating the eddy.
In fluid dynamics, eddy diffusion, eddy dispersion, or turbulent diffusion is a process by which fluid substances mix together due to eddy motion. These eddies can vary widely in size, from subtropical ocean gyres down to the small Kolmogorov microscales , and occur as a result of turbulence (or turbulent flow).
The name modon was coined by M. E. Stern as a pun on the joint USA-USSR oceanographic research program POLYMODE. [2] The modon is a dipole-vortex solution to the potential-vorticity equation that was theorized in order to explain anomalous atmospheric blocking events and eddy structures in rotating fluids, [3] and the first solution was obtained by Stern in 1975.
9. Kansas. When it comes to expensive states for homeowners, the state of Kansas doesn’t often come to mind. But it has an average property tax rate of 1.26%.
