Global energy spectrum of the general oceanic circulation

BA Storer, M Buzzicotti, H Khatri, SM Griffies… - Nature …, 2022 - nature.com
Advent of satellite altimetry brought into focus the pervasiveness of mesoscale eddies O

Global cascade of kinetic energy in the ocean and the atmospheric imprint

BA Storer, M Buzzicotti, H Khatri, SM Griffies… - Science …, 2023 - science.org
Here, we present an estimate for the ocean's global scale transfer of kinetic energy (KE),

Measuring scale-dependent shape anisotropy by coarse-graining: Application to inhomogeneous Rayleigh-Taylor turbulence

D Zhao, H Aluie - Physical Review Fluids, 2023 - APS
We generalize the “filtering spectrum” to probe scales along different directions by spatial
coarse-graining. This multidimensional filtering spectrum quantifies the spectral content of …
