The role of the North Atlantic overturning and deep ocean for multi-decadal global-mean-temperature variability [PDF]

Earth System Dynamics, 2014
Earth's climate exhibits internal modes of variability on various timescales. Here we investigate multi-decadal variability of the Atlantic meridional overturning circulation (AMOC), Northern Hemisphere sea-ice extent and global mean temperature (GMT)

Instability of Atlantic Meridional Overturning Circulation: Observations, Modelling and Relevance to Present and Future

Atmosphere, 2023
The Atlantic Meridional Overturning Circulation (AMOC) has changed dramatically during the glacial–interglacial cycle. One leading hypothesis for these abrupt changes is thermohaline instability.

Nonlinear Release of Subinertial Diurnal Internal Tides Forms Spiral Internal Solitary Waves

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Earth's rotation imposes a dynamical barrier on the free propagation of internal tides at high latitudes, raising questions about the fate of tidal energy poleward of the critical latitude. Satellite observations reveal spiral internal solitary waves (ISWs) along the continental slope of the South Orkney Plateau.

Machine-learning nowcasting of the Atlantic Meridional Overturning Circulation

APL Machine Learning
The Atlantic Meridional Overturning Circulation (AMOC) is a significant component of the global ocean system, which has so far ensured a relatively warm climate for the North Atlantic and mild conditions in regions, such as Western Europe.

Asymmetric response of the Atlantic Meridional Ocean Circulation to freshwater anomalies in a strongly-eddying global ocean model

Tellus: Series A, Dynamic Meteorology and Oceanography, 2017
The Atlantic Meridional Overturning Circulation (AMOC) responds sensitively to density changes in regions of deepwater formation. In this paper, we investigate the nonlinear response of the AMOC to large amplitude freshwater changes around Greenland ...

Physics of AMOC multistable regime shifts due to freshwater biases in an EMIC [PDF]

Earth System Dynamics
The Atlantic Meridional Overturning Circulation (AMOC), an important circulation system that modulates the global climate, has been identified as a potential tipping element.

Regional Trends in Northern Hemisphere Summer Extratropical Cyclone Activity and Their Link to Precipitation and Temperature Trends

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract In recent years a robust weakening of the storm tracks has been identified in reanalysis data. This trend has been linked to coinciding changes in surface temperature extremes and precipitation over land. Here we use a surface‐based metric to quantify regional trends in the boreal summertime low‐level extratropical cyclone activity (ECA) and ...

Limited influence of the Agulhas leakage on the Atlantic Meridional Overturning Circulation under present-day climate conditions

Communications Earth & Environment
The Agulhas leakage is expected to increase as the Southern Hemisphere westerly winds change under climate warming. An increased Agulhas leakage could potentially strengthen the Atlantic Meridional Overturning Circulation (AMOC).

Impact of Model Resolution on Antarctic Bottom Water Representation in Coupled Climate Models

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Antarctic Bottom Water (AABW) formation plays a crucial role in the climate system by driving the lower branch of the global overturning circulation, redistributing heat and salt, storing anthropogenic carbon dioxide, and delivering oxygen to the deep ocean.
