Curiosity Meets Discovery

Learn what amazing discoveries are coming out of Max Planck Institutes around the world in the lecture series “Curiosity Meets Discovery” by the Max Planck Institute for Neuroscience in Florida. It was our turn on 16 December 2021, and Prof. Bjorn Stevens held a talk about “Understanding Climate Science”. He will take you through new exa-scale computing resources that are enabling new climate simulation tools.

Curiosity Meets Discovery

Faster Faster — machine learning our way to a new generation of storm-resolving Earth system models

Exa-scale computing is enabling Earth-system models with greatly increased physical fidelity. These advances come at considerable computational cost. Machine learning, through its ability to efficiently identify, extract, and manipulate the information content of this new generation of models, can contribute to efforts to use these new models most effectively, advancing methods that may also generalize to a larger class of problems.

Clouds, Circulation and Climate Sensitivity — EUREC4A!

As part of the Hamburg KlimaCampus Colloquium series, Prof. Bjorn Stevens presents the science behind EUREC4A, a Barbadian-German-French led field campaign, its execution, and some snapshots of results emerging less than one year since the campaign's conclusion.

Climate factor clouds — the field campaign EUREC4A intends to answer one of climate science’s great mysteries

From 20 January through 20 February 2020, the EUREC4A (Elucidating the role of clouds-circulation coupling in climate) field study investigated trade wind clouds in the Tropical Atlantic. The international field study aimed at advancing understanding of the interplay between clouds, convection and circulation and their role in climate change. It was led by Prof Bjorn Stevens and Dr Sandrine Bony (Director of Research at the Laboratoire de Météorologie Dynamique). Their initiative builds on, and extends, a decade of cooperation with Barbadian scientists at the Caribbean Institute for Meteorology and Hydrology, under the leadership of its Principal, Dr David Farrell.

"Climate Science in the Age of Exascale" by Bjorn Stevens

With introduction by SC20 General Chair Christine E. Cuicchi, view the keynote talk at “SC20: The International Conference for High Performance Computing, Networking, Storage, and Analysis” featuring Professor Bjorn Stevens of the Max Planck Institute for Meteorology. Prof. Stevens discusses how exascale computing is impacting two opportunities that are changing the face of climate science. One arises from what exascale will enable; the other from what it will not.

How Cloudy is the Earth?

This video by Prof. Bjorn Stevens sheds light on clouds and their significance for the climate. It has, at least up until now, generally been thought that patterns of cloudiness are controlled by large scale weather systems. Research by Prof. Stevens and his co-authors show how small and intermediate scales of motion substantially pattern fields, adding a new piece to the puzzle of cloud-controlling factors. © Bjorn B.

Watching Water

What is it about the mighty water molecule that makes it so important? Does an understanding of a few key facts about water help us to better understand our atmosphere, patterns of weather, climate and climate change? In his lecture at the New England Aquarium on 15.10.2015, Prof Bjorn Stevens, Director at Max Planck Institute for Meteorology, answered these questions.

Clouds - more shade in the greenhouse?

What are the effects of clouds on climate change? MPI-M Director Prof. Bjorn Stevens investigates this question with his colleagues and explains the interrelations. (Only in German)
