• An Equatorial–Extratropical Dipole Structure of the Atlantic Niño 

      Nnamchi, Hyacinth C; Li, Jianping; Kucharski, Fred; Kang, In-Sik; Keenlyside, Noel; Chang, Ping; Farneti, Riccardo (Peer reviewed; Journal article, 2016)
      Equatorial Atlantic variability is dominated by the Atlantic Niño peaking during the boreal summer. Studies have shown robust links of the Atlantic Niño to fluctuations of the St. Helena subtropical anticyclone and Benguela ...
    • Pan-Atlantic decadal climate oscillation linked to ocean circulation 

      Nnamchi, Hyacinth C.; Farneti, Riccardo; Keenlyside, Noel Sebastian; Kucharski, Fred; Latif, Mojib; Reintges, Annika; Martin, Thomas (Journal article; Peer reviewed, 2023)
      Atlantic climate displays an oscillatory mode at a period of 10–15 years described as pan-Atlantic decadal oscillation. Prevailing theories on the mode are based on thermodynamic air-sea interactions and the role of ocean ...
    • Thermodynamic controls of the Atlantic Niño 

      Nnamchi, Hyacinth C; Li, Jianping; Kucharski, Fred; Kang, In-Sik; Keenlyside, Noel; Chang, Ping; Farneti, Riccardo (Peer reviewed; Journal article, 2015-11-26)
      Prevailing theories on the equatorial Atlantic Niño are based on the dynamical interaction between atmosphere and ocean. However, dynamical coupled ocean-atmosphere models poorly simulate and predict equatorial Atlantic ...
