The impact of resolution on the adjustment and decadal variability of the Atlantic Meridional Overturning Circulation in a coupled climate model [PDF]
, 2012 Variations in the Atlantic Meridional Overturning Circulation (MOC) exert an important influence on climate, particularly on decadal time scales. Simulation of the MOC in coupled climate models is compromised, to a degree that is unknown, by their lack ...

Mechanisms for Decadal Variability of Ocean Heat Uptake Inferred From Adjoint Sensitivities
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The occurrence of a period of slowdown in surface air temperature increase from 1998 to 2013 despite continued greenhouse gas emissions (the warming hiatus) has suggested that ocean heat uptake (OHU) is susceptible to decadal variability. Here, we identify mechanisms that lead to decadal changes in OHU to revisit the origin of the warming ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The surface climate impact of stratospheric polar vortex anomalies depends on their downward propagation (DP) into the troposphere. We find pronounced decadal variability in the winter frequency of stratospheric Northern Annular Mode (SNAM) events that exhibit DP (1951–2024).

The Evaluation of the North Atlantic Climate System in UKESM1 Historical Simulations for CMIP6
Journal of Advances in Modeling Earth Systems, 2020 Earth system models enable a broad range of climate interactions that physical climate models are unable to simulate. However, the extent to which adding Earth system components changes or improves the simulation of the physical climate is not well ...

Tropical Oceanic Causes of Interannual to Multidecadal Precipitation Variability in Southeast South America over the Past Century [PDF]
, 2010 Observations, atmosphere models forced by historical SSTs, and idealized simulations are used to determine the causes and mechanisms of interannual to multidecadal precipitation anomalies over southeast South America (SESA) since 1901.

South Atlantic Multidecadal Variability in the Climate System Model
Journal of Climate, 2002 Abstract Strong multidecadal variability is detected in a 300-yr integration of the NCAR Climate System Model in the South Atlantic region, through the application of two signal recognition techniques: the multitaper method and singular spectrum analysis.

Weather Regime Diversity, Transitions, and Trends Using Hexagonal Self‐Organizing Maps
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.Abstract Persistent atmospheric circulation patterns, or weather regimes, strongly modulate surface weather and extremes, yet their internal diversity, transitions, and trends remain less understood for North America. We apply a self‐organizing map (SOM) framework to represent North American weather regimes using daily 500‐hPa geopotential height ...
