In collaboration with Sarah Kang from the Max Planck Institute for Meteorology and Yohai Kaspi from the Weizmann Institute, Moritz investigate the impact of land-sea contrasts on the evolution of surface temperatures in the Pacific Ocean.
Over recent decades, the surface of the Eastern Pacific has experienced a cooling trend, contrary to the overall warming of the Earth. While some reasons for this phenomenon are understood, critical questions remain unanswered. For instance, will this cooling trend persist, or will the Eastern Pacific begin to warm - and if so, when? This question is crucial not only for local climates but also for global climate change, as the Pacific Ocean's surface temperatures play a vital role in regulating the Earth's climate.
To explore these hypotheses, Moritz conduct simulations using a global climate model developed by the Max Planck Institute for Meteorology, where he also completed his PhD.
As of November 2025, Moritz Günther leads the “Large-Scale Coupled Dynamics” group in the Climate Dynamics department at the Max Planck Institute for Meteorology. His research explores how large-scale atmospheric circulation patterns, such as the Hadley and Walker circulations, respond to global warming, focusing on the coupling between land, ocean, atmosphere, and cryosphere. Moritz completed his PhD at MPI-M in 2024 with distinction and recently received the Ines Biasoni Prize for his outstanding dissertation.
