Production and destruction of eddy kinetic energy in forced submesoscale eddy-resolving simulations [PDF]
Ocean Modelling, 2016 Abstract We study the production and dissipation of the eddy kinetic energy (EKE) in a submesoscale eddy field forced with downfront winds using the Process Study Ocean Model (PSOM) with a horizontal grid resolution of 0.5 km. We simulate an idealized 100 m deep mixed-layer front initially in geostrophic balance with a jet in a domain that permits ...

Large eddy simulation using high-resolution and high-order methods [PDF]
, 2009 Restrictions on computing power make direct numerical simulation too expensive for complex flows; thus, the development of accurate large eddy simulation (LES) methods, which are industrially applicable and efficient, is required.

Interaction of mesoscale vortices in the Lofoten Basin based on the GLORYS database
Russian Journal of Earth Sciences, 2020 We explore the interaction of mesoscale eddies in the Lofoten Basin of the Norwegian Sea using the GLORYS 12v1 eddy-resolving reanalysis. The Lofoten Basin is the area of the intensive ocean-atmosphere interactions and many mesoscale eddies are formed ...

Observed and numerically simulated kinetic energies for MODE eddies [PDF]
Journal of Physical Oceanography, 1980 Abstract It is demonstrated that the outcome of an intercomparison between data and the vertical distribution of eddy kinetic energy predicted by a previously developed numerical model of the MODE area is frequency dependent. In the range of periods from 50 to 150 or even to 400 days (one definition of the temporal mesoscale, the scale that the model ...

Offshore propagation of eddy kinetic energy in the California Current [PDF]
Journal of Geophysical Research: Oceans, 2001 Low‐pass‐filtered velocities obtained from surface drifters and surface geostrophic velocities estimated from TOPEX/Poseidon altimeter data have recently revealed a clear and robust seasonal cycle in the surface eddy kinetic energy (EKE) in the California Current (CC) [Kelly et al., 1998; Strub and James, 2000]. The seasonal cycle begins in spring when

Large-eddy simulation of turbulent flow over a rough surface [PDF]
, 2004 A family of wall models is proposed that exhibits more satisfactory performance than previous models for the large-eddy simulation (LES) of the turbulent boundary layer over a rough surface.The time and horizontally averaged statistics such as mean ...

Single super-vortex as a proxy for ocean surface flow fields [PDF]
Ocean Science, 2019 Empirical flow field data evaluation in a well-studied ocean region along the US west coast revealed a surprisingly strong relationship between the surface integrals of kinetic energy and enstrophy (squared vorticity).

Barotropic kinetic energy and enstrophy transfers in the atmosphere
Geophysical Research Letters, 2016 The midlatitude atmosphere is characterized by turbulent eddies that act to produce a depth‐independent (barotropic) mean flow. Using the NCEP (National Centers for Environmental Prediction) Reanalysis 2 data, the latitudinal dependence of barotropic ...
