Waves and vortices in the inverse cascade regime of stratified turbulence with or without rotation
We study the partition of energy between waves and vortices in stratified turbulence, with or
without rotation, for a variety of parameters, focusing on the behaviour of the waves and …

Balance dynamics in rotating stratified turbulence
If classical quasigeostrophic (QG) flow breaks down at smaller scales, it gives rise to
questions of whether higher-order nonlinear balance can be maintained, to what scale and …

Stability of an isolated pancake vortex in continuously stratified-rotating fluids
This paper investigates the stability of an axisymmetric pancake vortex with Gaussian
angular velocity in radial and vertical directions in a continuously stratified-rotating fluid. The …

Multi-scale methods for geophysical flows
Geophysical flows comprise a broad range of spatial and temporal scales, from planetary-to
meso-scale and microscopic turbulence regimes. The relation of scales and flow …

Evanescent and inertial-like waves in rigidly rotating odd viscous liquids
E Kirkinis, MO De La Cruz - Journal of Fluid Mechanics, 2024 - cambridge.org
Three-dimensional non-rotating odd viscous liquids give rise to Taylor columns and support
axisymmetric inertial-like waves (J. Fluid Mech., vol. 973, 2023, A30). When an odd viscous …

[HTML][HTML] Near resonant approximation of the rotating stratified Boussinesq system on a 3-torus
B Cheng, ZN Sakellaris - Physica D: Nonlinear Phenomena, 2023 - Elsevier
Based on a novel treatment of near resonances, we introduce a new approximation for the
rotating stratified Boussinesq system on three-dimensional tori with arbitrary aspect ratios …

Inertial-like waves in rigidly-rotating odd viscous liquids
E Kirkinis, MO de la Cruz - arxiv preprint arxiv:2307.00415, 2023 - arxiv.org
In this paper we show that an incompressible three dimensional or compressible in two
dimensions odd viscous liquid gives rise to both oscillatory and evanescent waves or a …

Investigations of non-hydrostatic, stably stratified and rapidly rotating flows
We present an investigation of rapidly rotating (small Rossby number). The investigation is
set in the context of a reduced model derived from the Boussinesq equations that retains …

Near-resonance approximation of rotating Navier–Stokes equations
B Cheng, ZN Sakellaris - Nonlinearity, 2023 - iopscience.iop.org
We formalise the concept of near resonance for the rotating Navier–Stokes equations, based
on which we propose a novel way to approximate the original partial differential equation …
