Shear Instability and Turbulent Mixing by Kuroshio Intrusion Into the Changjiang River Plume by Junbiao Tu, Jiaxue Wu, Daidu Fan, Zhiyu Liu, Qianjiang Zhang, William Smyth

“…The shear instabilities generate vigorous turbulent mixing with dissipation rate and vertical diffusivity up to O (10−4 m2 s−3) and O (10−1 m2 s−1), respectively, comparable to values associated with shear instabilities observed in river plumes and western boundary currents but several orders of magnitude larger than typical values in the open ocean. …”

Dwindling Effective Radiative Forcing of Large Volcanic Eruption: The Compensation Role of Ocean Latent Heat Flux by Ya Gao, Chaochao Gao

“…Four LH compensation hot spots overlapping with the trade wind regions are identified, together with three western boundary currents regions with intensified LH loss. Comparison between the 1258 Samalas and 1452 Unidentified eruptions suggests considerable modulation of the concurring El Nino‐Southern Oscillation on LH anomaly, which is further verified by CESM large ensemble sensitivity experiments. …”

Vertical structures of marine heatwaves by Ying Zhang, Yan Du, Ming Feng, Alistair J. Hobday

“…These vertical structures are influenced by ocean dynamical processes, including oceanic planetary waves, boundary currents, eddies, and mixing. The area and depth of all types of MHWs exhibit significant increasing trends over the past two decades. …”

Global Estimation of the Eddy Kinetic Energy Dissipation From a Diagnostic Energy Balance by Romain Torres, Robin Waldman, Julian Mak, Roland Séférian

“…The results show an intense dissipation near western boundary currents and in the Antarctic Circumpolar Current, where both large levels of energy and baroclinic conversion occur. …”

µ-shapes: Delineating urban neighborhoods using volunteered geographic information by Matt Aadland, Christopher Farah, Kevin Magee

“…Urban neighborhoods are a unique form of geography in that their boundaries rely on a social definition rather than a well-defined physical or administrative boundary. Currently, geographic gazetteers capture little more than then the centroid of a neighborhood, limiting potential applications of the data. …”

Submesoscale Variability and Basal Melting in Ice Shelf Cavities of the Amundsen Sea by Kalyan Shrestha, Georgy E. Manucharyan, Yoshihiro Nakayama

“…Abstract Melting of ice shelves can energize a wide range of ocean currents, from three‐dimensional turbulence to relatively large‐scale boundary currents. Here, we conduct high‐resolution simulations of the western Amundsen Sea to show that submesoscale eddies are prevalent inside ice shelf cavities. …”

Atlantic Meridional Overturning Circulation slowdown modulates wind-driven circulations in a warmer climate by Mohima Sultana Mimi, Wei Liu

“…Fingerprints of overturning slowdown are evident on Atlantic western boundary currents, encompassing a weaker northward Gulf Stream and Guiana Current and a stronger southward Brazil Current. …”

Modulation of the North Atlantic deoxygenation by the slowdown of the nutrient stream by F. Tagklis, T. Ito, A. Bracco

“…<p>Western boundary currents act as transport pathways for nutrient-rich waters from low to high latitudes (nutrient streams) and are responsible for maintaining midlatitude and high-latitude productivity in the North Atlantic and North Pacific. …”

On the porosity of barrier layers by J. Mignot, C. de Boyer Montégut, M. Tomczak

“…This is especially the case for barrier layers formed by mesoscale mechanisms (under the intertropical convergence zone for example and along western boundary currents) and equatorward of the sea surface salinity subtropical maxima. …”

Intra-Seasonal Variability of Sea Level on the Southwestern Bering Sea Shelf and Its Impact on the East Kamchatka and East Sakhalin Currents by Andrey Andreev

Influence of numerical schemes on current-topography interactions in 1/4&deg; global ocean simulations by G. Madec, J.-M. Molines, A.-M. Treguier, B. Barnier, J. Le Sommer, T. Penduff

“…The present study extends this investigation below the surface with a special focus on the Atlantic and reveals many improvements there as well: e.g. more realistic path, structure and transports of major currents (Gulf Stream, North Atlantic Current, Confluence region, Zapiola anticyclone), behavior of shedded rings, narrower subsurface boundary currents, stronger mean and eddy flows (MKE and EKE) at depth, beneficial enhancement of cyclonic (anticyclonic) flows around topographic depressions (mountains). …”

Dynamical pathways of Antarctic Bottom Water in the Atlantic by Stephens, J, Marshall, D

“…As a consequence, mass balance is maintained not by hypothesized western boundary currents as in the Stommel-Arons model, but by the interplay between topographic slope currents and interior recirculations. …”

Oceanic stochastic parametrizations in a seasonal forecast system by Andrejczuk, M, Cooper, F, Juricke, S, Palmer, T, Weisheimer, A, Zanna, L

On Constraining the Mesoscale Eddy Energy Dissipation Time‐Scale by J. Mak, A. Avdis, T. David, H. S. Lee, Y. Na, Y. Wang, F. E. Yan

“…We find that the dissipation time‐scale is shortest in the Southern Ocean, in the Western Boundary Currents, and on the western boundaries, consistent with the expectation that these regions are notable sites of baroclinic activity with processes leading to energy transfer out of the geostrophic mesoscales. …”

The Contemporary Challenge of the Sea: Science, Society, and Sustainability by David M. Karl

“…The North Pacific Subtropical Gyre (NPSG) is the largest of these gyres, and it is isolated from other ocean regions by permanent, clockwise-rotating boundary currents. The NPSG is also very old, with present boundaries having been established at least 10 million years ago (McGowan and Walker, 1985). …”

Variability and Uncertainty of Satellite Sea Surface Salinity in the Subpolar North Atlantic (2010–2019) by Lisan Yu

“…Satellite SSS products have difficulty producing the right annual cycle, particularly in the Labrador/Irminger seas where the SSS seasonality is dictated by the influx of Arctic low-salinity waters along the boundary currents. The study also found that there are basin-scale, time-varying drifts in the decade-long SMOS data records, which need to be corrected before the datasets can be used for studying climate variability of SSS.…”
