Scale‐dependent air‐sea exchange in the polar oceans: Floe‐floe and floe‐flow coupling in the generation of ice‐ocean boundary layer turbulence

S Brenner, C Horvat, P Hall… - Geophysical …, 2023 - Wiley Online Library
Sea ice is a heterogeneous, evolving mosaic of individual floes, varying in spatial scales
from meters to tens of kilometers. Both the internal dynamics of the floe mosaic (floe‐floe …

Enhanced ocean mixing during the passage of tropical cyclone

D Falor, B Gayen, D Sengupta… - Geophysical Research …, 2024 - Wiley Online Library
Tropical cyclones are among the most destructive natural disasters. However, lack of
detailed observations and the simplifications inherent in operational ocean models, lead to …

Oceanic frontal turbulence

PP Sullivan, JC McWilliams - Journal of Physical …, 2024 - journals.ametsoc.org
Upper-ocean turbulence results from a complex set of interactions between submesoscale

Flow structure of radiatively driven convection in inertial and rotating frames under steady and periodic radiative forcing

Y Chang, A Scotti - Physical Review Fluids, 2024 - APS
Freshwater achieves its maximum density at a pressure-dependent temperature which is
above the freezing point, close to 4° C at ambient pressure for pure water. If the temperature …

A finite-time ensemble method for mixed layer model comparison

L Johnson, B Fox-Kemper, Q Li… - Journal of Physical …, 2023 - journals.ametsoc.org

Deep-Cycle Turbulence in the Upper Pacific Equatorial Ocean: Characterization by LES and Heat Flux Parameterization

HT Pham, S Sarkar, WD Smyth… - Journal of physical …, 2024 - journals.ametsoc.org
Abstract Observations in the Pacific Equatorial Undercurrents (EUC) show that the nighttime
deep-cycle turbulence (DCT) in the marginal-instability (MI) layer of the EUC exhibits …

Diurnal warm layers in the ocean: Energetics, nondimensional scaling, and parameterization

M Schmitt, HT Pham, S Sarkar… - Journal of Physical …, 2024 - journals.ametsoc.org
Diurnal warm layers (DWLs) form near the surface of the ocean on days with strong solar
radiation, weak to moderate winds, and small surface-wave effects. Here, we use idealized …
