  • The nature of the El Niño-like variability in the Atlantic Ocean and its limited predictability remain unresolved. Here, via multi-model numerical experiments, the authors show that much of the variability can be explained by the interaction of stochastic atmospheric fluctuations with the ocean mixed layer.

  • The influence of the El Niño–Southern Oscillation on Atlantic marine systems and fisheries is complex. This Review outlines the mechanisms by which El Niño–Southern Oscillation impacts the tropical and South Atlantic, connecting physical climate perturbations to biogeochemical and ecological responses.

  • The relative roles of the ocean and atmosphere for the Atlantic Niño is poorly understood. Here, we show that its seasonality is governed by atmospheric diabatic heating that is associated with the seasonal migration of the inter-tropical convergence zone.

  • Sea surface temperature variability in the tropical North Atlantic exhibits a basin-wide mode and a coastal mode, with the former having a stronger impact on Atlantic hurricane activity, according to an analysis of climate data from remote sensing and reanalyses over the period 1982–2024.

  • Variations in Atlantic Ocean circulation on timescales of 10 to 15 years lead the pan-Atlantic Decadal Oscillation, a pattern of north-south bands of temperature anomalies, and may exert an important influence, suggests an analysis of observations from 1900 to 2009.

  • The observed strengthening of the atmospheric circulation and trade winds over the tropical Pacific Ocean over the past four decades counteracted global warming in the region, but is not captured in climate model simulations, according to a performance assessment of current climate models.
