North Atlantic overturning and water mass transformation in CMIP6 models

L. C. Jackson et al.

Summary: Climate models have difficulty capturing the overturning in subpolar North Atlantic accurately, casting doubt on their projections of the Atlantic Meridional Overturning Circulation. A comparison between models and observational estimates shows generally good agreement, particularly in the strength of overturning in the east. Additionally, the overturning reconstructed from surface flux driven water mass transformation is a good indicator of the actual overturning.

Seasonality of the Meridional Overturning Circulation in the subpolar North Atlantic

Yao Fu et al.

Summary: According to observations from the OSNAP array between 2014 and 2020, the subpolar overturning in the North Atlantic Ocean exhibits significant seasonality, with a peak in late spring and a trough in early winter, ranging about 9 Sv. Understanding the variability of the Atlantic Meridional Overturning Circulation is crucial for improving climate predictions.

Different mechanisms of Arctic and Antarctic sea ice response to ocean heat transport

Jake Aylmer et al.

Summary: Understanding the impact of ocean heat transport on sea ice extent can help reduce uncertainties in long-term climate projections. In this study, researchers found that the mechanisms of ocean heat transport's impact on sea ice are different in the northern and southern hemispheres. In the northern hemisphere, increased ocean heat transport leads to increased ocean heat convergence along the Atlantic sea ice edge and a reduction in pan-Arctic sea ice thickness. In the southern hemisphere, increased ocean heat transport results in basal melt and sea ice loss.

Resolution Dependence of Atmosphere-Ocean Interactions and Water Mass Transformation in the North Atlantic

Dylan Oldenburg et al.

Summary: The high-resolution simulations more accurately reproduce subpolar North Atlantic water mass transformation compared to the low-resolution simulations, which have larger biases. Despite these differences, the mechanisms of low-frequency AMOC variability are similar in both high- and low-resolution versions.

Mitigating Climate Biases in the Midlatitude North Atlantic by Increasing Model Resolution: SST Gradients and Their Relation to Blocking and the Jet

Panos J. Athanasiadis et al.

Summary: This study examines the response of certain biases in the midlatitude North Atlantic to increasing oceanic resolution. It shows that increasing resolution can significantly reduce cold sea surface temperature bias and improve the representation of European blocking and jet variability. The study also finds a relationship between meridional sea surface temperature gradients and atmospheric circulation, indicating the importance of North Atlantic SST anomalies in forcing significant atmospheric responses.

Summary: The collapse of AMOC is often used to explain past and future climate changes, but the actual implications may be less severe than expected. Even without AMOC, the Gulf Stream system will still transport significant amounts of heat and carbon poleward.

The evolution of the North Atlantic Meridional Overturning Circulation since 1980

Laura C. Jackson et al.

Summary: The Atlantic Meridional Overturning Circulation (AMOC) has a key role in the climate system, and its variability since 1980 has been analyzed. The AMOC has shown periods of both strengthening and weakening, with uncertain magnitudes of change. Different patterns of variability have been observed in the subpolar and subtropical regions of the North Atlantic. Research priorities include improving the monitoring of the AMOC, better representing processes in the North Atlantic, and distinguishing between anthropogenic weakening and internal variability.

Air-Sea Turbulent Heat Flux Feedback Over Mesoscale Eddies

Sophia Moreton et al.

Summary: The study highlights the importance of turbulent heat flux feedback over coherent mesoscale eddies in regulating sea surface temperature anomalies, estimating the THFF globally to be between 35 and 45 Wm-2K-1. The underestimation of THFF by coupled climate models can reach up to 80% when there is a disparity in resolution ratios between the atmosphere and ocean grids. Coordinated increase in ocean and atmosphere resolutions is crucial for accurately capturing the feedback processes at different scales.

Deep mixed ocean volume in the Labrador Sea in HighResMIP models

Torben Koenigk et al.

Summary: The study indicates that most climate models overestimate deep convection in the Labrador Sea, increasing ocean resolution leads to increased deep mixing, and increasing atmospheric resolution has a smaller effect. Simulated convection in the Labrador Sea is mainly influenced by heat release from the ocean to the atmosphere and vertical water mass stratification. Sub-grid scale mixing processes in the models might be imperfect and contribute to biases in deep convection.

An outsized role for the Labrador Sea in the multidecadal variability of the Atlantic overturning circulation

Stephen Yeager et al.

Summary: Climate models are essential for investigating North Atlantic variability, but recent observations question the importance of Labrador Sea processes. A preindustrial climate simulation with ocean mesoscale eddies reveals that AMOC variability can be traced to anomalous production of dense Labrador Sea Water, with buoyancy forcing in the western subpolar gyre playing a substantial driving role.

The Response of the Nordic Seas to Wintertime Sea Ice Retreat

Yue Wu et al.

Summary: The study investigates the ocean response to wintertime sea ice retreat in the Nordic seas using the HiGEM climate model. It finds that under global warming, the impact of ocean response differs from that caused by sea ice retreat, leading to changes in water column mixing, temperature, and salinity.

Distinct sources of interannual subtropical and subpolar Atlantic overturning variability

Yavor Kostov et al.

Summary: This research reconstructs and attributes intermonthly and interannual AMOC variability at two observational arrays to the recent history of surface wind stress, temperature and salinity. The analysis reveals that on interannual timescales, AMOC variability at 26 degrees N is primarily driven by local wind stress, while at subpolar latitudes, it is influenced by a combination of wind stress and surface buoyancy anomalies.

Subpolar North Atlantic western boundary density anomalies and the Meridional Overturning Circulation

F. Li et al.

Summary: The study using trans-basin observation data found that deep water formation in the subpolar North Atlantic has minimal impact on the overturning circulation, contrary to previous modeling studies. The authors revealed that changes in western boundary currents do not significantly influence the variability of the subpolar overturning circulation over observational time scales.

Summary: The impacts of the declining Atlantic Meridional Overturning Circulation (AMOC) in future climate change are uncertain. Different models show variations in temperature, rainfall, and jet-stream patterns due to the AMOC decline, highlighting the need for continued observational efforts to constrain its response.

Role of air-sea fluxes and ocean surface density in the production of deep waters in the eastern subpolar gyre of the North Atlantic

Tillys Petit et al.

Summary: Winter convection in the North Atlantic Ocean plays a key role in the global climate by producing dense waters that contribute to the Atlantic Meridional Overturning Circulation (AMOC). Recent studies emphasize the significance of the Irminger and Iceland basins in the production of North Atlantic Deep Water, with buoyancy forcing transforming surface waters into deep waters. The research shows that air-sea fluxes and ocean surface density are crucial factors influencing the densification of surface water and the transformation of subpolar mode water in the Iceland Basin.

Horizontal circulation across density surfaces contributes substantially to the long-term mean northern Atlantic Meridional Overturning Circulation

Rong Zhang et al.

Summary: The results suggest that the Arctic Ocean, rather than the Greenland Sea, is the northern terminus of the mean Atlantic Overturning Circulation; open-ocean deep convection, in either the Labrador or Greenland Seas, contributes minimally to the mean Atlantic Overturning Circulation, hence it would not necessarily be substantially weakened by a shutdown of open-ocean deep convection; horizontal circulation across sloping isopycnals contributes substantially (more than 40%) to the maximum mean northeastern subpolar Atlantic Overturning Circulation.
