Aleksei Koldunov

Dr. Aleksei Koldunov is a Researcher in the Climate Dynamics group at the Alfred Wegener Institute in Bremerhaven, Germany. His work focuses on advancing Earth system modeling and understanding ocean-atmosphere interactions, particularly in the context of climate dynamics. He specializes in high-resolution ocean models (e.g., FESOM, NEMO) and their application to study phenomena like Rossby waves, mesoscale eddies, and vertical mixing processes in the tropical and North Atlantic.

His research integrates remote sensing data (e.g., satellite altimetry, Argo floats) with numerical simulations to analyze ocean circulation patterns, steric sea-level fluctuations, and the impact of topography on wave dynamics. He contributes to large-scale projects like nextGEMS, aiming to develop kilometer-scale Earth system models for improved climate projections.

Key areas of investigation include the Agulhas Current leakage, Lofoten Basin eddies, and the role of vertical mixing in tropical Atlantic circulation. His interdisciplinary work bridges physical oceanography, climate modeling, and geophysical fluid dynamics, with publications spanning topics from solar wind interactions to coastal shelf wave dynamics.

Dr. Koldunov collaborates on multi-year simulations and model development to address unresolved questions in climate science, such as the representation of small-scale processes in global models. His expertise in model validation and parameterization techniques supports efforts to enhance the accuracy of climate predictions.
