  2. Eddy (fluid dynamics) - Wikipedia

    en.wikipedia.org/wiki/Eddy_(fluid_dynamics)

    Mesoscale ocean eddies are characterized by currents that flow in a roughly circular motion around the center of the eddy. The sense of rotation of these currents may either be cyclonic or anticyclonic (such as Haida Eddies). Oceanic eddies are also usually made of water masses that are different from those outside the eddy. That is, the water ...

  3. Eddy saturation and eddy compensation - Wikipedia

    en.wikipedia.org/wiki/Eddy_saturation_and_eddy...

    Eddy saturation and eddy compensation are phenomena found in the Southern Ocean. Both are limiting processes where eddy activity increases due to the momentum of strong westerlies , and hence do not enhance their respective mean currents.

  4. Eddy pumping - Wikipedia

    en.wikipedia.org/wiki/Eddy_pumping

    Observed vertical velocities of eddy pumping are in the order of one meter per day. However, there are regional differences. In regions where kinetic energy is higher, such as in the Western boundary current, eddies are found to generate stronger vertical currents than eddies in open ocean. [7]

  5. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    In electromagnetism, an eddy current (also called Foucault's current) is a loop of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field. Eddy currents flow in closed loops within conductors, in planes ...

  6. Relative wind stress - Wikipedia

    en.wikipedia.org/wiki/Relative_wind_stress

    Figure 3: Damping of eddy due to use of relative wind stress compared to wind stress in resting ocean approximation. As seen in Figure 2, when the wind velocity and ocean current velocity are in the same direction, the relative wind stress is smaller than the resting ocean wind stress. In other words, less positive work is using relative wind ...

  7. Eddy diffusion - Wikipedia

    en.wikipedia.org/wiki/Eddy_diffusion

    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).

  8. Ocean general circulation model - Wikipedia

    en.wikipedia.org/wiki/Ocean_general_circulation...

    These boundary conditions on ocean flows are difficult to define and to parameterize, which results in a high computationally demand. Ocean modeling is also strongly constrained by the existence in much of the world's oceans of mesoscale eddies with time and space scales, respectively, of weeks to months and tens to hundreds of kilometers ...

  9. Richardson number - Wikipedia

    en.wikipedia.org/wiki/Richardson_Number

    The Richardson number, or one of several variants, is of practical importance in weather forecasting and in investigating density and turbidity currents in oceans, lakes, and reservoirs. When considering flows in which density differences are small (the Boussinesq approximation ), it is common to use the reduced gravity g' and the relevant ...
