Ocean‐Scale Interactions From Space
Autor: Patrice Klein, Guillaume Lapeyre, Lia Siegelman, Bo Qiu, Lee‐Lueng Fu, Hector Torres, Zhan Su, Dimitris Menemenlis, Sylvie Le Gentil
Publikováno v: Earth and Space Science, Vol 6, Iss 5, Pp 795-817 (2019)
Satellite observations of the last two decades have led to a major breakthrough emphasizing the existence of a strongly energetic mesoscale turbulent eddy field in all the oceans. This ocean mesoscale turbulence is characterized by cyclonic and antic

Optimal Perturbations of an Oceanic Vortex Lens
Autor: Thomas Meunier, Claire Ménesguen, Xavier Carton, Sylvie Le Gentil, Richard Schopp
Publikováno v: Fluids, Vol 3, Iss 3, p 63 (2018)
The stability properties of a vortex lens are studied in the quasi geostrophic (QG) framework using the generalized stability theory. Optimal perturbations are obtained using a tangent linear QG model and its adjoint. Their fine-scale spatial structu

Characterization of internal tide incoherence : Eulerian versus Lagrangian perspectives
Autor: Zoé Caspar-Cohen, Aurélien Ponte, Noé Lahaye, Xavier Carton, Xiaolong Yu, Sylvie Le Gentil
Publikováno v: Journal Of Physical Oceanography (0022-3670) (American Meteorological Society), 2022-06, Vol. 52, N. 6, P. 1245-1259
Journal of Physical Oceanography
Journal of Physical Oceanography, 2022, 52 (6), pp.1245-1259. ⟨10.1175/JPO-D-21-0088.1⟩
The Lagrangian and Eulerian surface current signatures of a low-mode internal tide propagating through a turbulent balanced flow are compared in idealized numerical simulations. Lagrangian and Eulerian total (i.e., coherent plus incoherent) tidal amp

At low latitudes in the ocean, the deep currents are shaped into narrow jets flowing eastward and westward, reversing periodically with latitude between 15°S and 15°N. These jets are present from the thermocline to the bottom. The energy sources an

Low-Mode Internal Tide Propagation in a Turbulent Eddy Field
Autor: Patrice Klein, Michael Dunphy, Sylvie Le Gentil, Aurélien Ponte
Publikováno v: Journal Of Physical Oceanography (0022-3670) (Amer Meteorological Soc), 2017-03, Vol. 47, N. 3, P. 649-665
Understanding how internal tides distort and lose coherence as they propagate through the ocean has been identified as a key issue for interpreting data from the upcoming wide-swath altimeter mission SWOT. This study addresses that issue through the

Layering and turbulence surrounding an anticyclonic oceanic vortex: in situ observations and quasi-geostrophic numerical simulations
Autor: Bach Lien Hua, Bruno Marsset, Richard Schopp, Sylvie Le Gentil, Hidenori Aiki, Claire Ménesguen
Publikováno v: Journal Of Fluid Mechanics (0022-1120) (Cambridge Univ Press), 2013-09, Vol. 731, P. 418-442
Evidence of persistent layering, with a vertical stacking of sharp variations in temperature, has been presented recently at the vertical and lateral periphery of energetic oceanic vortices through seismic imaging of the water column. The stacking ha
