Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Decadal predictions are affected by initialization shocks and drift, typically diagnosed in ocean circulation or temperature. It is not known, however, to what extent the drift can affect atmospheric dynamics. Here we investigate how the drift causes spatial shifts in the location of key large‐scale atmospheric circulation features such as the

Environmental Research CommunicationsThe Atlantic Meridional Overturning Circulation (AMOC) exerts a major influence on global climate. There is much debate about whether the current strong AMOC may collapse as a result of anthropogenic forcing and/or internal variability.

International Journal of Climatology, Volume 46, Issue 11, September 2026.This study investigates summer Greenland atmospheric blocking using the Lagrangian tracking Python package blocktrack applied to ERA5 reanalysis and CMIP6 models. Two types of blocks—upstream (Northern Canada origin) and retrograding (Northern Atlantic origin)—are distinguished, with upstream blocks driving recent observed frequency increasing trends ...

AGU Advances, Volume 7, Issue 6, September 2026.Abstract Future projections of oxygen and water mass age change in the upper Pacific Ocean show a consistent pattern: strong deoxygenation and increased age in the well‐ventilated subtropical gyres, contrasted by weak deoxygenation and younger age in the poorly ventilated tropical oxygen minimum zones.

Projected AMOC Weakening Controls Future Diatom Decline in the Subpolar North Atlantic Ocean
Earth's Future, Volume 14, Issue 9, September 2026.Abstract Climate models consistently project a decline in diatom net primary production (NPP) under high‐emission scenarios in the highly productive subpolar North Atlantic. However, the magnitude of this decline remains highly uncertain and varies substantially across models, limiting our ability to anticipate its ecological and biogeochemical ...

Impact of Ekman Pumping on the Meridional Coherence of the AMOC
Geophysical Research LettersThe effect of wind‐induced vertical velocity on the meridional coherence of Atlantic meridional overtuning circulation (AMOC) is examined using theory, observations, and a numerical model.

Mechanisms of AMOC variability simulated by the NEMO model [PDF]
, 2013 Abstract. We have investigated dominant mechanisms of the Atlantic Meridional Overturning Circulation (AMOC) variability at 26.5° N (without the Ekman component) on monthly timescales using 1° and 1/4° NEMO model data. All data were detrended and the seasonal cycle removed.

Communications Earth & EnvironmentAs a major ocean circulation system, the Atlantic Meridional Overturning Circulation (AMOC) may approach a critical transition under anthropogenic forcing, yet how large-scale AMOC changes imprint on regional circulation pathways remains incompletely ...
