Working group Regional Weather and Climate Modeling

The Regional Weather and Climate Modeling working group deals with various phenomena within the climate system, focusing in particular on the interactions between the atmosphere, ocean, and cryosphere. The overarching goal is to better understand the role of these interactions and their impact on climate variability across different scales. To this end, we use coupled numerical models in combination with reanalysis and observational data to answer questions about predictability, long-term trends, and extreme events.
