Since February 2014, I am leading a new Research Group which studies links between atmospheric circulation and extreme weather events (BMBF-funded project Sacre-X).
Nov 2016 - Our new paper gives additional evidence that resonance of planetary waves has a hand in many recent extreme weather events.
Sept 2016 - Kick-off workshop at University of Oxford of project GOTHAM (Globally Observed Teleconnections and their role and representation in Hierarchies of Atmospheric Models).
Sept 2016 - New paper on atmospheric waviness published in ERL, here a media-friendly explanations and a video.
May 2016 - Our new resonance paper, explaining recent spring and summer weather extremes, gets published in PNAS
Apr 2016 - Launch of our video in collaboration with Climate Media Factory explaining Rossby waves, extreme weather and wave-resonance.
Apr 2016 - Our new wave-resonance paper, investigating the Balkan floods of 2014, is published in Science Advances - some good coverage by Mashable
Mar 2016 - For its 5th anniversary, Nature Climate Change looks back at some highlight papers including Coumou & Rahmstorf (2012)
Mar 2016 - Our new paper on Causal Effect Neworks is published in J Clim, and some commentaries by us on extreme rainfall appeared in Nature
Dec 2015 - Our new paper on the influence of storm tracks on prolonged weather extremes gets published in Scientific Reports - here a summary of our findings.
Oct 2015 - SacreX-team participates at Berlin´s Science Hack event, here some footage.
July 2015 - Our new paper shows that record-breaking rainfall extremes are on the rise, see also the press-release and an interview with Reuters
Mar 2015 - Our Science paper "The weakening summer circulation in the Northern Hemisphere mid-latitudes" (open access reprint) gets published, and covered by Science, Climate Central, Carbon Brief, Environmental Research Web and Washington Post.
Nov 2014 - World Bank report Turn down the heat III is published. Here some infographics, videos, interviews and media-coverage.
A geophysicist by training, I have worked 2.5 years as marine geophysicist in the offshore industry, before starting my PhD research at ETH in Zurich. Here, I worked on the development of efficient multiphase fluid flow transport schemes which I used to study hydrothermal systems.
In 2008, I joined PIK to develop a novel atmosphere model Aeolus which is part of our in-house Earth System model POEM (PIK flagship activity NEXT). In Aeolus high-frequency variability is parameterized which makes the model computationally very efficient compared to General Circulation Models. We use it to study the sensitivity of large-scale atmospheric circulation to different drivers.
Since early 2010, I am studying the link between extreme weather events (like heat waves, droughts and heavy precipitation) and global warming. This works includes statistical analysis of heat waves, heavy rainfall and atmospheric circulation. Further, we use climate models and Causal Effect Networks to understand dynamical mechanisms which cause extremes.
My scientific interests include climate dynamics, extreme events, droughts, complex earth system, predictability, causal inference. Technical interests include parallel programming, C++, object-oriented design, etc, etc, etc...
