Progressive emergence of canopy gravity waves during the afternoon–evening transition

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Large‐eddy simulations are used to investigate the afternoon‐to‐evening transition of turbulence over a forest canopy and its coupling with atmospheric boundary‐layer dynamics. As surface cooling strengthens stability and weakens near‐canopy winds, canopy turbulence transitions progressively to internal gravity waves that dominate the evening flow ...

Comparative analysis of four types of mesoscale eddies in the north pacific subtropical countercurrent region – part I spatial characteristics

Frontiers in Marine Science, 2022
The North Pacific Subtropical Countercurrent (STCC) region has high mesoscale eddy activities due to its complex circulation structure. This study divides these mesoscale eddies into four types: cyclonic cold-core eddy (CCE), anticyclonic warm-core eddy (

Spontaneous zonal symmetry breaking of tropical rain belt

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Precipitable‐water snapshots show how a sea surface temperature (SST)‐forced tropical rain belt can remain zonally elongated or spontaneously reorganize into a localized convective cluster. The simulations identify the SST conditions favoring this zonal convective self‐aggregation and relate the transition to changes in boundary‐layer circulation and ...

Full‐Depth Scalings for Isopycnal Eddy Mixing Across Continental Slopes Under Upwelling‐Favorable Winds

Journal of Advances in Modeling Earth Systems, 2021
Mesoscale eddy mixing profoundly modulates the ocean tracer budgets, and is typically parameterized via the isopycnal eddy diffusivity in ocean climate models.

Relationships between dryline intensity, deep moist convection and regional circulation over interior southern Africa

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We explore the relationship between dryline intensity, convective activity, and the regional circulation over southern Africa during summer by comparing weak and strong convective drylines with each other. We find that strong drylines result in stronger convection with up to 3.6 times more lightning strokes adjacent to the dryline than on weak dryline ...

Quantifying the Role of Mesoscale-Driven Processes of Nitrate Supply Within an Iceland Basin Eddy Dipole

, 2011
This study quantitatively assesses the mesoscale spatial variability in local nitrate transport and the net nitrate flux associated with an open ocean eddy dipole, using novel data from the SUV?6 ultra?violet (UV) nitrate sensor integrated with SeaSoar ...

Hydrodynamic modelling of mesoscale eddies in the Black Sea [PDF]

Ocean Dynamics, 2005
A three dimensional structure of mesoscale circulation in the Black Sea is simulated using the Proudman Oceanographic Laboratory Coastal Ocean Modelling System. A number of sensitivity tests reveal the response of the model to changes in the horizontal resolution, time steps, and diffusion coefficients. Three numerical grids are examined with x-fine (3.

Damping of climate-scale oceanic variability by mesoscale eddy turbulence

, 2021
International audienceThe impact of mesoscale eddy turbulence on long-term, climatic variability in the ocean's buoyancy structure is investigated using observations from a mooring deployed in the Drake Passage, Southern Ocean.

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

Small, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

The Multi‐Scale Response of the Eddy Kinetic Energy and Transport to Strengthened Westerlies in an Idealized Antarctic Circumpolar Current

Geophysical Research Letters
The Southern Ocean's eddy response to changing climate remains unclear, with observations suggesting non‐monotonic changes in eddy kinetic energy (EKE) across scales.
