Prof. Jin-Song von Storch shows in a new paper that climate variability on ultra-long timescales is, contrary to common understanding, not determined by the responsible internal dynamics on the same timescales. Her study is an impetus for a new way of thinking. Her result provides first evidence showing that climate as a dynamical system is not…

With the first day of spring we also kick off the full module-team of the BMBF-funded WarmWorld project. Within this project, the Max Planck Institute for Meteorology and its partners are developing the scalability of the Earth-system model ICON for exascale applications. That means that the model will be faster, better and easier to run,…

Accurately capturing location, diurnal as well as seasonal variability of the tropical rainbelt, over land and over ocean, has remained beyond reach for climate models relying on statistical representations of convection. In this context, simulations explicitly resolving convection over regional domains with fixed sea-surface temperatures…

The Max Planck Institute for Meteorology, together with the German Climate Computing Centre (DKRZ) and the University of Hamburg, is once again participating in Girls'Day on 27 April 2023.

In a recent study in the journal of Geoscientific Model Development Leonidas Linardakis and his colleagues demonstrate how coarse-grained component concurrency increases the parallel workload of Earth system models and results in an increased number of compute nodes that can be used efficiently in parallel. The additional dimension of parallelism…

In a study in The Cryosphere, researchers at the Max Planck Institute for Meteorology examined the effect of basal friction and sea level variation on the evolution of ice rises and ice rumples using three-dimensional idealized ice-sheet simulations including the surrounding ice shelves. They show that the current state of ice rises and ice rumples…

Do thunderstorms in the atmosphere affect the meandering of ocean currents? What is the effect of ocean eddies on the carbon budget? Investigating such questions requires simulating the Earth system at a grid spacing finer than 10 km. This is now possible with the release of the first version of the ICON-Sapphire configuration developed at the Max…

Limiting global warming to 1.5 degrees Celsius is currently not plausible, as is shown in a new, central study released by Universität Hamburg’s Cluster of Excellence “Climate, Climatic Change, and Society” (CLICCS). Climate policy, protests, and the Ukraine crisis: the participating researchers systematically assessed to what extent social changes…

Dr Chetankumar Jalihal, a postdoc at the Max Planck Institute for Meteorology (MPI-M), successfully applied for a Humboldt Research Fellowship for Postdoctoral scientists. Since January 2023, he continues his research in the research group "Ocean Physics" at the MPI-M — now focusing on the Atlantic Meridional Overturning Circulation (AMOC) and the…

In a joint publication whose author list comprises a substantial fraction of all scientists of the department “The Ocean in the Earth System” at the Max Planck Institute for Meteorology (MPI-M), another milestone of the ICON project was reached. In the paper “ICON-O: The Ocean Component of the ICON Earth System Model—Global Simulation…
