About Me
Research topics
- North Atlantic SST variability
- European heat events
- Warm Conveyor Belt activity
- High-resolution climate modeling
- Forecast skill assessment
My research involves the investigation of various driving mechanisms for European heat events. A particular focus is on the influence of surface temperatures in the subpolar North Atlantic. I examine observational and climate model data to discover potential links and patterns between North Atlantic SST variability and European climate. This includes dynamical and thermodynamical processes in the atmosphere such as the Warm Conveyor Belt Activity, which is sensitive to ocean surface temperatures in the North Atlantic. A better understanding of these processes in and over the North Atlantic helps to improve the predictability of heat events over Europe.
My current and future postdoctoral research involves investigating the atmospheric response to mesoscale eddies in the North Atlantic Ocean in the frame of the project OceanWeather of the Hans-Ertel-Centre for weather research. Using the ICON climate model and different horizontal resolutions, the influence of sea surface temperatures on the atmospheric circulation can be better assessed.
