Deep Eddy Kinetic Energy in the Tropical Pacific From Lagrangian Floats [PDF]

open access: yesJournal of Geophysical Research: Oceans, 2020
AbstractAt the ocean surface, satellite observations have shown evidence of a large spectrum of waves at low latitudes. However, very little is known about the existence and properties of the deep variability. Most of the subsurface observations rely on localized measurements, which do not allow for a global estimation of this variability.

Global coarse-grained mesoscale eddy statistics based on integrated kinetic energy and enstrophy correlations [PDF]

open access: yesOcean Science, 2022
Recently, Jánosi et al. (2019) introduced the concept of a “vortex proxy” based on an observation of strong correlations between integrated kinetic energy and integrated enstrophy over a large enough surface area.

The Lorenz energy cycle: trends and the impact of modes of climate variability

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2021
The atmospheric circulation is driven by heat transport from the tropics to the polar regions, embedding energy conversions between available potential and kinetic energy through various mechanisms.

The Impact of Horizontal Resolution on Energy Transfers in Global Ocean Models

open access: yesFluids, 2017
The ocean is a turbulent fluid with processes acting on a variety of spatio-temporal scales. The estimates of energy fluxes between length scales allows us to understand how the mean flow is maintained as well as how mesoscale eddies are formed and ...

Numerical simulation and decomposition of kinetic energy in the Central Mediterranean: insight on mesoscale circulation and energy conversion [PDF]

open access: yesOcean Science, 2011
The spatial and temporal variability of eddy and mean kinetic energy of the Central Mediterranean region has been investigated, from January 2008 to December 2010, by mean of a numerical simulation mainly to quantify the mesoscale dynamics and their ...

Modelling and simulation of turbulence in unsteady separated and suddenly-expanded flows [PDF]

open access: yes, 2011
The scope of this PhD thesis is the simulation of turbulence in time-dependent, separated and suddenly-expanded channel flows. High-resolution and very high-order numerical methods have been employed in the framework of Implicit Large Eddy Simulation ...

First observation of fluid-like eddy-dominant bursty bulk flow turbulence in the Earth’s tail plasma sheet

open access: yesScientific Reports, 2023
Turbulence is a ubiquitous phenomenon in neutral and conductive fluids. According to classical theory, turbulence is a rotating flow containing vortices of different scales.

Production and destruction of eddy kinetic energy in forced submesoscale eddy-resolving simulations [PDF]

open access: yesOcean 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 ...
