Anna von der Heydt

I am an assistant professor at the Institute for Marine and Atmospheric Research at Utrecht University, the Netherlands. My work focusses on (palaeo-) climate phenomena and transition behaviour in climate using a hierarchy of climate models and stochastic dynamical systems approaches. Moreover I’m using state-of-the-art (high resolution) climate models to quantify the state-dependent climate response to forcing. Currently I am active in the Netherlands Earth System Science Centre (NESSC), the Centre for Complex Systems Studies in Utrecht (CCSS) and a H2020 funded project on tipping points in the Earth System (TiPES).

COVID-19-related drop in anthropogenic aerosol emissions in China and corresponding cloud and climate effects

COVID-19-related drop in anthropogenic aerosol emissions in China and corresponding cloud and climate effects

While a previous blog entry dealt with the question whether we can use lessons from the nonlinear nature of climate for projections of the Covid-19 pandemic, there is now a first example of how the pandemic can teach us something on climate. The several weeks long lockdown of China made February 2020 an exceptional month in terms of air quality; aerosol emissions were tremendously reduced leading ...[Read More]

Workshop report: Mathematics of the Economy and Climate

Just before the summer a group of about 40 scientists gathered in an old Monastery in the Netherlands (Kontakt der Kontinenten, Soesterberg) for a rather special collaborative workshop entitled “Mathematics of the economy and climate”. Mathematicians, climate scientists and economists – a group of scientists that normally does not mix and are rather unfamiliar with each other’s researc ...[Read More]

Welcome to the Nonlinear Processes in Geosciences Blog!

We are happy to announce that the growing Nonlinear Processes in Geosciences (NP) community has a new unifying platform where newsworthy information on different topics will be published, with the main aim to reach many scientists at a time. Thus, this is the official launch of the Nonlinear Processes in Geosciences Blog! We hope this platform could serve as a starting point to strengthen our comm ...[Read More]
