Global climatology of submesoscale restratification using machine learning [PDF]

Scientific Reports
Submesoscale eddies are important in setting the stratification in the ocean surface mixed layer and transporting energy between large and small scale motions. However, the study of submesoscale on a global scale has been hindered by a shortage of global,

Seasonality in submesoscale turbulence [PDF]

Nature Communications, 2015
AbstractAlthough the strongest ocean surface currents occur at horizontal scales of order 100 km, recent numerical simulations suggest that flows smaller than these mesoscale eddies can achieve important vertical transports in the upper ocean. These submesoscale flows, 1–100 km in horizontal extent, take heat and atmospheric gases down into the ...

Submesoscale Instabilities in Mesoscale Eddies [PDF]

Journal of Physical Oceanography, 2017
AbstractSubmesoscale processes have been extensively studied in observations and simulations of fronts. Recent idealized simulations show that submesoscale instabilities also occur in baroclinic mesoscale cyclones and anticyclones. The instabilities in the anticyclone grow faster and at coarser grid resolution than in the cyclone.

A survey of submesoscale currents [PDF]

Geoscience Letters, 2019
Abstract Submesoscale currents are pervasive throughout the ocean. They have intermediate space and time scales—neither mesoscale nor microscale—that have made them elusive for measurements and modeling until recently. In this brief article, a survey is presented of their primary characteristics and interpretive explanations, intended for a broad ...

Observations reveal vertical transport induced by submesoscale front [PDF]

Scientific Reports
Submesoscale fronts, with horizontal scale of 0.1–10 km, are key components of climate system by driving intense vertical transports of heat, salt and nutrients in the ocean. However, our knowledge on how large the vertical transport driven by one single

The seasonal cycle of submesoscale flows [PDF]

Ocean Modelling, 2015
AbstractThe seasonal cycle of submesoscale flows in the upper ocean is investigated in an idealised model domain analogous to mid-latitude open ocean regions. Submesoscale processes become much stronger as the resolution is increased, though with limited evidence for convergence of the solutions.

Submesoscale generation by boundaries [PDF]

Journal of Marine Research, 2011
An important dynamical question involves how oceanic balanced flows lose energy. Recent numerical and analytical studies suggest topography catalyzes energy exchanges between balanced flows and a variety of unbalanced phenomena, which presumably leads ...

Submesoscale inverse energy cascade enhances Southern Ocean eddy heat transport. [PDF]

Nat Commun, 2023
Oceanic eddy-induced meridional heat transport (EHT) is an important process in the Southern Ocean heat budget, the variability of which significantly modulates global meridional overturning circulation (MOC) and Antarctic sea-ice extent.

Observed regimes of submesoscale dynamics in the Southern Ocean seasonal ice zone [PDF]

Nature Communications
Submesoscale flows, occurring at scales of about 1–10 km, are crucial to the vertical transport of heat and other tracers in the upper ocean. These flows are energized by instabilities that extract potential energy from lateral buoyancy gradients, which ...

Microfibers Accumulation within a Mediterranean Submesoscale Cyclone. [PDF]

Environ Sci Technol
Cyclonic eddies are widespread upper ocean features known to enhance primary productivity via nutrient upwelling; yet, their role in the transport and retention of anthropogenic contaminants remains poorly understood. Here, we present high-resolution oceanographic measurements from a submesoscale cyclone in the Western Mediterranean Sea, revealing a ...
