Testing mechanisms of wave generation in the lower stratosphere using superpressure balloons

 
Floating overpressure balloon in front of a snow-covered mountain panorama Dr. Laura Köhler and Dr. Claudia Stephan from the Max Planck Institute for Meteorology together with their colleague Brian Green, Postdoc at Stanford University, used superpressure balloons to test the ability of global storm-resolving models to represent convectively induced gravity waves. They find that the models’ spatial structure of the wave field, including their spatial correlation as a function of distances, matches the observations well, but the amplitude of the background flux in the…

Climate Dynamics research field — a portrait of new director Sarah Kang

 
Photo of Sarah Kang When she opens the door to her office and invites you in with a friendly smile, it quickly becomes clear: Sarah Kang is still new at the Max Planck Institute for Meteorology. The room is half empty, some of the office furniture has not yet been delivered and there are unpacked moving boxes in the corner. It was only in August that the Korean woman took up her post as Director of a new department — the Climate Dynamics department. Now, two months later, everything seems to be going well: Kang's…

Max Planck Institute for Meteorology welcomes Friedrich Wilhelm Bessel-awardee Prof. Tiffany Shaw

 
Portrait Tiffany Shaw Professor Tiffany Shaw, who is a recipient of the Friedrich Wilhelm Bessel Research Award by the Alexander von Humboldt Foundation and a globally acclaimed atmospheric physicist affiliated with the University of Chicago, chose the Max Planck Institute for Meteorology (MPI-M) in Hamburg as her host institution for a period of one year. During her research stay, she will extend her work on the response of extra-tropical storm-tracks to include factors influencing their inter-hemispheric asymmetry.

How the Atlantic overturning got its observing system

 
The RAPID observing system has monitored the Atlantic Meridional Overturning Circulation (AMOC) at 26.5°N since 2004. Many physical oceanographers and climate scientists routinely use these measurements or refer to them, and the observing system’s 20th anniversary in April 2024 marks it as one of the longest dynamical time series in oceanography. But the history of ideas that have led to the establishment of the RAPID monitoring system has been shrouded in mystery for all but a select few. In a…

An oscillating wind system in the tropical stratosphere: future evolution and new projections

 
The “quasi-biennial oscillation” (QBO) is a well-known wind system characterized by alternating layers of westerly and easterly winds encircling the whole globe that descend through the equatorial stratosphere with a roughly two year periodicity. However, so far it has been still uncertain how the QBO may change due to global warming. A team of scientists led by researcher Henning Franke from the Max Planck Institute for Meteorology now used global storm-resolving simulations with the climate…

Director's Research Group

 
The Arctic region has undergone the most rapid surface warming observed globally in recent decades. Arctic variability may be important for influencing mid-latitude weather, but the question how and how much is under debate.   We investigate dynamical processes linking the Arctic to midlatitude weather and climate in climate model simulations and observation-based reanalyses. In a recent publication (Tyrlis et al., 2019), we highlighted the central role of atmospheric blocking, when…

Towards improved CO2 predictions

 
What factor limits the predictability of atmospheric CO2 concentration? Scientists from the Max-Planck-Institute for Meteorology, in collaboration with colleagues from the USA, Canada and Italy, have found that Earth system models have very similar mechanisms to predict terrestrial carbon fluxes, but that this similarity does not translate to CO2 predictability. The main reason for this limitation is the difference in regions that contribute most to interannual variations in atmospheric CO2…
