MPI-M-researcher Julia Windmiller overturns a textbook explanation for the low wind speeds that tormented sailing ships in the tropics: Rather than resulting from rising air masses, they appear to be a created by large areas of sinking air in the tropics. The new study has now been published in the renowned journal Geophysical Research Letters.
MPI-M researchers and their partner institutions are currently performing atmospheric measurements over the equatorial Atlantic with eight coordinated measurement campaigns. They want to find out what controls the structure of the tropical rain belt, how it will change in the future and what this means for weather patterns. A variety of state-of-the-art research platforms are being used for the measurements – from ships to satellites.
The Max Planck Institute for Meteorology (MPI-M) is pleased to announce that Moritz Günther has started a 4-year postdoctoral position in the German-Israeli Max Planck-Weizmann Postdoctoral Programme. Together with Prof. Sarah Kang, Head of the Climate Dynamics Department and Director at MPI-M, and Prof. Yohai Kaspi, Department of Geophysical Fluid Dynamics at the Weizmann Institute of Science in Tel Aviv, Israel, he will spend the next four years as a postdoc investigating how land-sea…
Five master's students from Ghana, Senegal, Nigeria, Benin, and Guinea, participating in the WASCAL program, had the unique opportunity to gain hands-on research experience during the ORCESTRA campaign. The West African Science Service Centre on Climate Change and Adapted Land Use (WASCAL), supported by the German Federal Ministry of Education and Research (BMBF), aims to strengthen scientific capacity in West Africa to address the challenges of climate change and sustainable land use.
We humans benefit from the oceans’ tremendous capacity to absorb greenhouse gases. Due to the low temperature of the water, the Arctic Ocean absorbs an especially large amount of CO2 in relation to its size. Due in part to climate change, this effect will be less pronounced in the future. A new study released by Universität Hamburg’s Cluster of Excellence CLICCS shows how much CO2 is released into the atmosphere in the Arctic Ocean by the erosion of coastal permafrost.
The ORCESTRA started his performance on August 10th in Cap Verde. The PERCUSION gives the beat by flying back and forth across the belt of deep rain over the tropical Atlantic Ocean, while the MAESTRO directs his plane around fields of broken cumuli around Cap Verde to understand how convective storms form and organize. The maestro’s BOWTIE is travelling by ship from Cap Verde to Barbados scrutinizing those convective storms from below and their interactions with the ocean. From the orchestra’s…
It’s not just the people of Hamburg and the many tourists who know that Hamburg is particularly beautiful in the summer. The Max Planck Institute for Meteorology (MPI-M) traditionally welcomes many renowned international guest researchers to Hamburg and the Institute during the summer months. Here we introduce you to three of our guests — Dr. Martin Singh (Australia), Prof. Dr. Allison Wing and Prof. Dr. Brian Mapes (both USA) — more specifically: what research projects are they working on…

In a new study Moritz Günther, Hauke Schmidt, Claudia Timmreck, and Matthew Toohey show how aerosol perturbations in the stratosphere lead to a cascade of unanticipated effects with global implications. The heating from the aerosol changes the stratospheric circulation which perturbs the distribution of radiant energy flows, eventually influencing the surface temperature in ways that affect the climate system globally.
A time series of a climate variable often resembles a random sequence. This apparent randomness is generally attributed to the unpredictable and chaotic nature of dynamical systems. So far, there exists no theory about how a climate model, as such a purely deterministic dynamical system, can produce random solutions. In a recent publication, Jin-Song von Storch shows that randomness, and with that irreversibility, in solutions of a purely deterministic dynamical system emerge from a hitherto…
Researchers at the Max Planck Institute for Meteorology shed light on what may happen if the frozen soils thaw in response to global heating. Landscapes in the Arctic and subarctic zone are often very wet with water saturated soils and an extensive lake- and wetland cover shaping the moisture and energy exchange with the atmosphere. To some extent, the abundance of water is caused by the presence of permafrost, that is those parts of the ground that remain perennially frozen. Such soil layers…
The Max Planck Institute for Meteorology is continuing its partnership with the Indian Institutes for Science Education and Research (IISERs) as part of the Max Planck Society's cooperation program launched in 2023 to enable research stays at Max Planck Institutes for talented Master's students from India. The aim of the program is to promote early interaction between Max Planck Institutes and outstanding Indian students. Both parties can get to know each other better through a research stay…
