Deciphering the Link Between Modeling Errors and the North Atlantic Surface Warming Pattern Projected by CMIP5 and CMIP6 Models

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The North Atlantic Subpolar Gyre (NASG) has warmed much less than the global ocean over recent decades, thereby suggesting a human‐caused slowdown of the Atlantic Meridional Overturning Circulation (AMOC). This North Atlantic “warming hole” is also found in climate projections, yet with a model‐dependent timing, location and intensity. Here we

Twenty Years of Satellite Observations Reveal a Shift in the Diurnal Trend of Dust Optical Depth Over West Africa

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract West Africa is the largest global source of mineral dust, with significant impacts on climate, air quality, and biogeochemical cycles. While temporal variations in dust loading from daily to interannual scales are well studied, the long‐term evolution of the diurnal cycle itself is often overlooked.

Spurious Drifts in the ITCZ Location and Associated Atmospheric Circulation in Decadal Climate Predictions

open access: yesGeophysical 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
