Cascades and transitions in turbulent flows

A Alexakis, L Biferale - Physics Reports, 2018 - Elsevier
Turbulent flows are characterized by the non-linear cascades of energy and other inviscid
invariants across a huge range of scales, from where they are injected to where they are …

A quantitative scaling theory for meridional heat transport in planetary atmospheres and oceans

B Gallet, R Ferrari - AGU Advances, 2021 - Wiley Online Library
The meridional temperature profile of the upper layers of planetary atmospheres is set
through a balance between differential radiative heating by a nearby star, or by intrinsic heat …

Spatiotemporal dynamics in two-dimensional Kolmogorov flow over large domains

D Lucas, R Kerswell - Journal of fluid mechanics, 2014 - cambridge.org
Kolmogorov flow in two dimensions–the two-dimensional (2D) Navier–Stokes equations
with a sinusoidal body force–is considered over extended periodic domains to reveal …

Coherent vortex versus chaotic state in two-dimensional turbulence

AN Doludenko, SV Fortova, IV Kolokolov, VV Lebedev - Annals of Physics, 2022 - Elsevier
We examine analytically and numerically the state of a two-dimensional fluid in a finite box
appearing as a result of the inverse cascade supported by a permanent pumping. We argue …

Spontaneous suppression of inverse energy cascade in instability-driven 2-D turbulence
