A recent study by Geet George, Bjorn Stevens (both from the Max Planck Institute for Meteorology) and Marcus Klingebiel (now at Leipzig University) along with Sandrine Bony and Raphaela Vogel (Laboratoire de Météorologie Dynamique in Paris) shows that aspects of the atmospheric circulation tend to control low-level cloudiness at the mesoscale…

In a review article appearing in the Quarterly Journal of the Royal Meteorological Society, Dr. Claudia Stephan (Max Planck Institute for Meteorology), Prof. Nedjeljka Žagar (Universität Hamburg) and Prof. Ted Shepherd (University of Reading) provide their perspective on present understanding of waves and coherent flows in the atmosphere, and their…

In a new study, Dr. Laura Suarez, Dr. Sebastian Milinski and Dr. Nicola Maher evaluate which models best capture the real-world climate with its internal variability and response to external forcings in observed surface temperatures. They used a novel framework that utilizes the unique design and power of SMILE experiments, single model initial-con…

Dr. Cathy Hohenegger, scientist and leader of the group “Precipitating Convection” at the Max Planck Institute for Meteorology (MPI-M), was awarded her Habilitation (the highest qualification level in the German university system) on 24 June 2021.

On 27 June 2021, after a 10-day quarantine of the participants, the RV SONNE will set off from Emden under the cruise guidance of Prof. Peter Brandt from GEOMAR in Kiel and co-leader Dr. Julia Windmiller from the Max Planck Institute for Meteorology (MPI-M). The cruise under the name "Mooring Rescue" serves to control and collect scientific…

Climate neutrality by 2045 is Germany´s goal, and debates on how to get there are in full swing. To achieve it, profound changes are needed. Climate simulations show why this is important. Without them, climate policy remains blind. How climate models work and why they are reliable is explained by the Deutsches Klima-Konsortium (DKK) on the new…

In a recent study in Geophysical Research Letters, Dr. Dian Putrasahan and colleagues from the department “The Ocean in the Earth System” at the Max Planck Institute for Meteorology (MPI-M), from Universität Hamburg and from the UK MetOffice Hadley Centre investigated the effect of resolving ocean eddies on global mean surface temperature (GMST)…

Dr. Claudia Stephan, Minerva Fast Track group leader in the department “The Atmosphere in the Earth System” at the Max Planck Institute for Meteorology (MPI-M) has been accepted into the Elisabeth Schiemann Kolleg of the Max Planck Society. She is the first researcher at MPI-M to be included in this select group of outstanding young female…

In a new paper, Veit Lüschow, Jin-Song von Storch and Jochem Marotzke from the Max Planck Institute for Meteorology show that the Atlantic meridional overturning circulation could respond unexpectedly to anticipated future changes in the winds near Antarctica: Besides increasing the northward transport of warm water near the surface, stronger winds…

Large volcanic eruptions can inject sulfur containing gases into the stratosphere where they build sulfate aerosols. These particles, on the one hand, scatter incoming sunlight away from the Earth, resulting in a temporary global mean surface cooling. On the other hand, they absorb infrared radiation and thereby warm the lower stratosphere. These…
