Journal Article
Kafiabad, H. A., & Vanneste, J. (2023). Computing Lagrangian means. Journal of Fluid Mechanics, 960, Article A36. https://doi.org/10.1017/jfm.2023.228

Lagrangian averaging plays an important role in the analysis of wave–mean-flow interactions and other multiscale fluid phenomena. The numerical computation of Lagrangian means, e.g. from simulation data, is, however, challenging. Typical implementati... Read More about Computing Lagrangian means.

Inertia-gravity-wave diffusion by geostrophic turbulence: the impact of flow time dependence (2023)
Journal Article
Cox, M. R., Kafiabad, H. A., & Vanneste, J. (2023). Inertia-gravity-wave diffusion by geostrophic turbulence: the impact of flow time dependence. Journal of Fluid Mechanics, 958, Article A21. https://doi.org/10.1017/jfm.2023.83

The scattering of three-dimensional inertia-gravity waves by a turbulent geostrophic flow leads to the redistribution of their action through what is approximately a diffusion process in wavevector space. The corresponding diffusivity tensor was obta... Read More about Inertia-gravity-wave diffusion by geostrophic turbulence: the impact of flow time dependence.
