A group of scientists mostly from the Max Planck Institute for Meteorology (MPI-M) studied the representation of tropical precipitation by models participating in the Coupled Modelling Intercomparison Projects (CMIP). Their analysis of output from models spanning twenty years of development over three CMIP phases, found little general improvement in the representation of tropical precipitation.
A new study in Climate Dynamics by Andreas Lang and Uwe Mikolajewicz from the Department "The Ocean in the Earth System" at the Max Planck Institute for Meteorology (MPI-M) shows that the intensity of extreme storm surges on the German North Sea coast is projected to increase under rising greenhouse gas emissions. With the help of numerical ensemble simulations of a special regionally coupled climate model, the authors examined these extreme events.
Researchers around the globe are using numerical climate models in an attempt to find answers to the question: How would global warming change our world? Earth’s climate is extremely complex and difficult to model. Each climate model has its specific strengths and weaknesses. In order to estimate the bandwidth of possible future climate developments, the results of all major climate models worldwide are conjointly evaluated and compared under the auspices of the World Climate Research Project…
The Paris climate agreement from December 2015 recognized that the world is warming and that humans are primarily responsible for it. This provided a powerful impetus not only for climate policy but also for climate research. To address the resulting new challenges, the Cluster of Excellence “Climate, Climatic Change, and Society” (CLICCS) at Universität Hamburg established a long-term program in 2019, spanning the range from basic research on climate dynamics and climate-related social…
Scientists at the Universität Hamburg and the Max Planck Institute for Meteorology (MPI-M) are measuring a weather phenomenon that we all know well, especially these days: thunderstorms. The weather is warm and nice, and suddenly a thunderstorm pops in the sky and produces extreme downpours for a brief instant. During such events, the air temperature cools considerably, especially near the ground due to the evaporation of the precipitation. Strong wind gusts occur, but after a few minutes the…
The International Max Planck Research School on Earth System Modelling (IMPRS-ESM) is a PhD programme jointly run by the Max Planck Institute for Meteorology (MPI-M) and Universität Hamburg since 2002. Recently Prof Martin Claussen, Director and Head of the PhD programme at MPI-M, and Dr Antje Weitz, Coordinator of the IMPRS-ESM, celebrated the 200th doctoral candidate: Diego Jiménez de la Cuesta Otero successfully defended his PhD thesis entitled „Historical Warming and Climate Sensitivity“.
A new study in Nature Climate Change, led by Paul Keil of the Max Planck Institute for Meteorology, uses climate model simulations to identify additional drivers of the so-called North Atlantic warming hole.
A new study by Dr Nicola Maher, Dr Flavio Lehner and Prof Jochem Marotzke demonstrates that in the coming 15 years any individual point on the globe in climate models could observe a cooling (or lack of warming) trend even under increasing greenhouse gas emissions.
In two new publications, scientists at the Max Planck Institute for Meteorology (MPI-M) studied the current and future development of extreme heat events. They identified major risk hotspots for different forms of extreme heat under different global warming levels, and disentangled the drivers of increasingly intense European heat extremes.
In a new study Aaron Spring and Dr. Tatiana Ilyina, researchers at the Max Planck Institute for Meteorology (MPI-M), were able to show that the atmospheric CO2 concentration is predictable for three years in advance [Fig. 1 c] and that the land carbon cycle limits longer predictability.
