A scalable Bayesian framework for modern sea-level inference
Dan Heathcote, Thomas Holland, Adrian Mag +7
This paper presents a scalable Bayesian framework for the inference of modern-day sea-level change and surface mass redistribution. To motivate this approach, we first review and q…
Prandtl number effects on extreme mixing events in forced stratified turbulence
Nicolaos Petropoulos, Miles M. P. Couchman, Ali Mashayek +2
Relatively strongly stratified turbulent flows tend to self-organise into a 'layered anisotropic stratified turbulence' (LAST) regime, characterised by relatively deep and well-mix…
Turbulent disruption of density staircases in stratified shear flows
Nicolaos Petropoulos, Ali Mashayek, Colm-cille P. Caulfield
Formation of step-like 'density staircase' distributions induced by stratification and turbulence has been widely studied and can be explained by the 'instability' of a sufficientl…
Tweed and wireframe: accelerated relaxation algorithms for multigrid solution of elliptic PDEs on stretched structured grids
Thomas Bewley, Ali Mashayek, Daniele Cavaglieri +1
Two new relaxation schemes are proposed for the smoothing step in the geometric multigrid solution of PDEs on 2D and 3D stretched structured grids. The new schemes are characterize…
Goldilocks mixing in oceanic shear-induced turbulent overturns
A. Mashayek1, C. P. Caulfield2, 3 +1
We present a new physically-motivated parameterization, based on the ratio of Thorpe and Ozmidov scales, for the irreversible turbulent flux coefficient $Γ_{\mathcal M}= {\mathcal…
Surface reflection of bottom generated oceanic lee waves
Lois Baker, Ali Mashayek
Lee waves generated by stratified flow over rough bottom topography in the ocean extract momentum and energy from the geostrophic flow, causing drag and enhancing turbulence and mi…
