The spatiotemporal evolutions of equatorial Atlantic sea surface temperature anomalies (SSTAs) during Atlantic Niño events and the associated climate impacts on the surrounding continents are extremely diverse. In this study, we construct longitude‐time maps of equatorial Atlantic SSTAs for each observed Atlantic Niño event during 1948–2019 and perform a spatiotemporal empirical orthogonal function analysis to identify the four most frequently recurring Atlantic Niño varieties. The first two… 
The Extraordinary Equatorial Atlantic Warming in Late 2019
Sea‐surface temperatures (SSTs) in the eastern equatorial Atlantic are subject to variability on interannual timescales but during the last 20 years, this variability has shown comparatively little

Atlantic Niños dominate the equatorial Atlantic variability during boreal summer (June–August). The coupled ocean‐atmosphere processes associated with Atlantic Niños have been extensively documented.
Indian Ocean Dipole leads to Atlantic Niño
TLDR
It is found that the enhanced rainfall in the western tropical Indian Ocean during positive IOD weakens the easterly trade winds over the tropical Atlantic, causing warm anomalies in the central and eastern equatorial Atlantic basin and therefore triggering the Atlantic Niño.
Java-Sumatra Niño/Niña and associated regional rainfall variability
A phenomenon referred to here as Java-Sumatra Niño/Niña (JSN or JS Niño/Niña) is characterized by the appearance of warm/cold sea surface temperature anomalies (SSTAs) in the coastal upwelling
Diabatic heating governs the seasonality of the Atlantic Niño
TLDR
It is shown that diabatic heating variability associated with the seasonal migration of the Inter-Tropical Convergence Zone controls the seasonality of the Atlantic Niño, implying that the oceanic impact on the atmosphere is smaller than previously thought.
How do Climate Modes Shape the Chlorophyll‐a Interannual Variability in the Tropical Atlantic?
Chlorophyll‐a concentration (Chl‐a) observed by satellite shows a marked seasonal and interannual variability in the tropical Atlantic. This study analyzes how the remotely sensed surface Chl‐a
Physical drivers of pelagic sargassum bloom interannual variability in the Central West Atlantic over 2010–2020
Since 2011, unprecedented pelagic sargassum seaweed blooms have occurred across the tropical North Atlantic, with severe socioeconomic impacts for coastal populations. To investigate the role of
Atlantic Niño/Niña Prediction Skills in NMME Models
The Atlantic Niño/Niña, one of the dominant interannual variability in the equatorial Atlantic, exerts prominent influence on the Earth’s climate, but its prediction skill shown previously was
