Assessment of the southern polar and subpolar warming in the PMIP4 last interglacial simulations using paleoclimate data syntheses by Q. Gao, Q. Gao, Q. Gao, E. Capron, L. C. Sime, R. H. Rhodes, R. Sivankutty, X. Zhang, B. L. Otto-Bliesner, M. Werner

“…<p>Given relatively abundant paleo-proxies, the study of the last interglacial (LIG, <span class="inline-formula">∼</span> 129–116 000 years ago, ka) is valuable to understanding the responses and feedback of the Southern Ocean and Antarctica in a warmer-than-preindustrial climate. …”

The very-high-resolution configuration of the EC-Earth global model for HighResMIP by E. Moreno-Chamarro, E. Moreno-Chamarro, E. Moreno-Chamarro, T. Arsouze, T. Arsouze, M. Acosta, P.-A. Bretonnière, M. Castrillo, E. Ferrer, A. Frigola, D. Kuznetsova, E. Martin-Martinez, P. Ortega, S. Palomas

“…By contrast, VHR shows a larger warm bias and overly low sea ice extent over the Southern Ocean. Such biases in surface temperature have an impact on the atmospheric circulation aloft, connected with a more realistic storm track over the North Atlantic yet a less realistic storm track over the Southern Ocean compared to the lower-resolution model versions. …”

Plausible Last Interglacial Antarctic Ice Sheet Changes Do Not Fully Explain Antarctic Ice Core Water Isotope Records by Huiling Zou, Louise C. Sime, Nancy A. N. Bertler, Elizabeth D. Keller, Eric W. Wolff

“…The remaining discrepancies between the simulated and observed core‐mean water isotope changes suggest that LIG simulations also need to include the influences of reduced Antarctic sea ice, a warmer Southern Ocean, and resultant shifts in vapor source regions to produce a more satisfactory match to δ18O observed at ice core sites.…”

Record Low Antarctic Sea Ice Cover in February 2022 by John Turner, Caroline Holmes, Thomas Caton Harrison, Tony Phillips, Babula Jena, Tylei Reeves‐Francois, Ryan Fogt, Elizabeth R. Thomas, C. C. Bajish

“…Although no individual sector was at a record low, at the minimum there were negative sea ice anomalies in all sectors of the Southern Ocean, with the largest in the Ross (contributing 46%) and Weddell Seas (26%). …”

Identifying Ocean Submesoscale Activity From Vertical Density Profiles Using Machine Learning by Leyu Yao, John R. Taylor, Dani C. Jones, Scott D. Bachman

“…One data set is extracted from a large‐eddy simulation (LES) in a 4 km by 4 km domain and the other from a regional model for a sector in the Southern Ocean. We show that the adapted PCM can identify regions with high submesoscale activity, as characterized by the vorticity field (i.e., where surface vertical vorticity ζ is similar to Coriolis frequency f and Rossby number Ro=ζ/f∼O(1)), using solely the vertical density profiles, without any additional information on the velocity, the profile location, or horizontal density gradients. …”

A Feasibility Study on Monitoring Crustal Structure Variations by Direct Comparison of Surface Wave Dispersion Curves from Ambient Seismic Noise by K. Muhumuza

“…Maximum amplitudes of secondary microseisms were observed during local winter when the Southern Ocean experiences winter storms. The Rayleigh wave group velocity ranges between 2.1 and 3.7 km/s, considering our period range studied. …”

“…To improve the representation of the Southern Ocean, a scale-aware form of the Gent–McWilliams parameterization and the application of a partial-slip lateral boundary condition on momentum in the Southern Ocean have been added, resulting in a stronger and more realistic Antarctic Circumpolar Current (ACC) transport and a reduction in the temperature and salinity biases along the shelf of Antarctica. …”
