Geometric approaches to Lagrangian averaging

AD Gilbert, J Vanneste - Annual Review of Fluid Mechanics, 2024 - annualreviews.org
Lagrangian averaging theories, most notably the generalized Lagrangian mean (GLM)
theory of Andrews and McIntyre, have been primarily developed in Euclidean space and …

R Barkan, K Srinivasan… - Journal of Physical …, 2024 - journals.ametsoc.org
The interactions between oceanic mesoscale eddies, submesoscale currents, and internal
gravity waves (IWs) are investigated in submesoscale-resolving realistic simulations in the …

Scale‐Awareness in an Eddy Energy Constrained Mesoscale Eddy Parameterization

J Mak, JR Maddison, DP Marshall… - Journal of Advances …, 2023 - Wiley Online Library
There is an increasing interest in mesoscale eddy parameterizations that are scale‐aware,
normally interpreted to mean that a parameterization does not require parameter …

Reference map technique for Lagrangian exploration of coherent structures

I Hayat, RT Black, GI Park - arXiv preprint arXiv:2401.06303, 2024 - arxiv.org
We explore the application of the reference map technique, originally developed for the
Eulerian simulation of solid mechanics, in Lagrangian kinematics of fluid flows. Unlike …

Using nonlinear interactions to quantify and improve timestepping accuracy in the Rotating Shallow Water Equations

TC Andrews - 2024 - search.proquest.com
A key objective for the next generation of weather and climate models is the reduction of wall-
clock time. This is to ensure that predictions are made within operational timeframes and that …
