The tropical Atlantic exhibits significant ocean variability from daily to decadal time scales, driven by complex ocean dynamics and air-sea interactions. This session is devoted to advancing the understanding of these dynamics and their climatic impacts on both adjacent and remote regions, including their interactions with other tropical basins.

Relevant ocean processes include upper and deep ocean circulation, eddies, tropical instability waves, mixing, and upwelling. We further welcome studies analyzing marine heat waves, mechanisms related to climate modes such as Atlantic, Dakar and Benguela Niños, the Atlantic Meridional Mode and the South Atlantic Ocean Dipole, effects of climate change, extratropical as well as interbasin teleconnections, and local biological impacts of ocean variability.

Finally, we seek for studies that explore the causes and impacts of systematic model errors in simulating the local to regional Atlantic climate variability. Submissions based on direct observations, reanalysis, model simulations and machine learning techniques are welcome.
