I am a member of the Steering Committee of EPOC – Explaining and Predicting the Ocean Conveyor Project. I serve as Co-Lead of Work Package 2 (Key Processes of Meridional Transport) and Work Package 4 (Future AMOC Evolution, Impacts and Abrupt Changes). In addition, within Work Package 3, I investigate the impact of greenhouse gas forcing on the AMOC through its sea surface height fingerprint.

Studying climate change is a very complex challenge, but sometimes simplicity unexpectedly emerges. Researchers have used idealized experiments with Earth system models to derive an approximation that allows them to estimate how the atmospheric carbon content will develop under different emission scenarios and what this means for the climate.
For the first time, scientists have resolved extremely intense tropical cyclones and their effect on the ocean carbon cycle in a global Earth system model. Using two category-4 hurricanes in the North Atlantic as examples, the study reveals a cascade of physical-biogeochemical effects including uptake of carbon dioxide and regional-scale phytoplankton bloom.
For the first time, scientists were able to study the behavior of eddies measuring just a few kilometers in size in a realistic simulation of the North Atlantic using an innovative computational grid. It enabled them to determine how efficiently these sub-mesoscale eddies transported heat, salt, and trace gases between the ocean surface and the underlying water masses. This quantitative assessment within a realistic ocean model with unprecedented resolution allowed for a better understanding of…
The nextGEMS project, which ended this year, has paved the way for a more natural use of Earth information systems with local granularity. Its major successes include further developing two kilometer-scale Earth system models, ICON and IFS-FESOM, and producing climate simulations at the kilometer scale over a period of 30 years. In addition, the project participants have developed new workflows for analyzing such data and formed an active and motivated community that is eagerly anticipating the…
In his new book, Guy Brasseur, former director at the Max Planck Institute for Meteorology and head of the “Environmental Modeling” research group, recounts the history of atmospheric science. In this interview, he shares how the book came about and explains why a historical perspective is beneficial, not only for students.
A team led by the Max Planck Institute for Meteorology and the German Climate Computing Center has received the prestigious Gordon Bell Prize for Climate Modelling for their groundbreaking work at the intersection of climate science and high-performance computing. Their achievement—a landmark simulation of the full Earth system with the ICON model at 1.25-kilometer resolution—overcame a challenge long considered impossible. The prize was awarded at the Supercomputing Conference (SC25) in St.…

Melting ice in the Arctic is causing an increasing amount of freshwater to enter the North Atlantic, which is expected to result in a weakening of the Atlantic overturning circulation. However, many modeling studies make unrealistic assumptions about how this water enters the ocean. A new study shows that the timing, location, and source of freshwater input can have a considerable impact on its eventual fate and should therefore be taken into account in future model experiments.
How do the ocean and land surfaces shape the large-scale atmospheric circulation? As of November, this question is being addressed by the research group “Large-Scale Coupled Dynamics” in Sarah Kang’s department. The team is headed by Moritz Günther.
Observations show that the Intertropical Convergence Zone has a complex and asymmetrical structure. For example, precipitation is more pronounced at the southern edge of this tropical rain belt than at the northern edge. Using storm-resolving ICON simulations, researchers have explained the mechanisms behind this structure.
