Towards multi-resolution global climate modeling with ECHAM6–FESOM. Part I: model formulation and mean climate (2015, background): “The latter argue that the delayed Antarctic warming is related to the fact that the Southern Ocean forms part of the upwelling branch of the Meridional Overturning Circulation (Marshall and Speer 2012) and is thus stronger influenced by the slowly responding deep ocean Fig.”
Turning Ocean Mixing Upside Down (2015, positive): “…they ﬂow southward along density surfaces to the Southern Ocean, where the Roaring Forties lift them to the surface to be transformed into intermediate waters that ﬂow back toward Antarctica and the North Atlantic, thereby closing the overturning loop [see the review by Marshall and Speer (2012)].”
The ocean’s role in setting the mean position of the Inter-Tropical Convergence Zone (2013, background): “The cell is associated with deep convection and sinking in the NH and upwelling to the surface through Ekman suction in the SH (see Marshall and Speer 2012).”
An Evaluation of the Large‐Scale Atmospheric Circulation and Its Variability in CESM2 and Other CMIP Models (2020, background): “…of weather and surface climate in the SH and also has global implications through the wind stress influence on Southern Ocean upwelling (Gent, 2016; Marshall & Speer, 2012) and the leakage of warm salty water from the Indian Ocean into the Atlantic through the Agulhas current (Biastoch et al.,…”
Antarctic climate response to stratospheric ozone depletion in a fine resolution ocean climate model (2012, background): “As summarized in Marshall and Speer [2012], in the current debate about resolved versus parameterized eddies in the Southern Ocean, little has been said about sea ice, despite the fact that at its maximum extent, sea ice spans the region from the Antarctic continent to the Polar Front.”
Climate model configurations of the ECMWF Integrated Forecasting System (ECMWF-IFS cycle 43r1) for HighResMIP (2018, methodology): “Although the ORCA025 version of the NEMO ocean model used in ECMWF-IFS-MR/-HR is considered “eddypermitting”, it is far from fully resolving the energetic mesoscale eddy field that extends along the path of the ACC (Marshall and Speer, 2012).”
Resolving and Parameterising the Ocean Mesoscale in Earth System Models (2020, background): “For example, the Southern Ocean mean state and its response to expected future changes in wind stress forcing, including the upper cell of its overturning circulation which influences heat and carbon uptake and isopycnal slopes that drive the ACC, result from a subtle balance between larger opposing”
A roadmap for Antarctic and Southern Ocean science for the next two decades and beyond (2014, background): “The Antarctic Circumpolar Current connects the world ocean basins (Rintoul 2011), while the overturning circulation links the deep and shallow layers of the ocean (Marshall & Speer 2012).”
Max Planck Institute Earth System Model (MPI-ESM1.2) for the High-Resolution Model Intercomparison Project (HighResMIP) (2018, methodology): “The modification of the original PP formulation consists of a parameterization for wind-induced mixing that decays exponentially with depth (Marsland et al., 2003). Convection is parameterized by enhanced eddy diffusivity (kv = 0.1 m2 s−1). For our simulations, we corrected a bug associated with the”
The Dependence of Southern Ocean Meridional Overturning on Wind Stress (2011, background): “Although the circulation is highly idealized, it shares several important features with the real Southern Ocean MOC, as described, for example, by Rintoul et al. (2001), Lumpkin and Speer (2007), Talley (2008), or Marshall and Speer (2011).”
Overturning circulation driven by breaking internal waves in the deep ocean (2013, background): “It is believed that the return flow of the mid-depth cell, formed in the North Atlantic, is primarily along density surfaces all the way to the Southern Ocean, where the dense waters come to the surface and are transformed back to light waters [e.g., Marshall and Speer, 2012, review].”
