Dr. Annika Oertel

About myself

My research focuses on the role of diabatic processes for the large-scale circulation and the interaction between processes across scales.
Already during my PhD at ETH Zurich I focused on the interplay of smaller-scale convection embedded in a large-scale and strongly ascending coherent airstream in extratropical cyclones (the so-called warm conveyor belt - WCB). At KIT, I started to work at the interface between microphysical processes and the larger-scale extratropical circulation. Together with Corinna Hoose (Cloud Physics, KIT), Christian Grams (Large-scale Dynamics and Predictability), and Annette Miltenberger (Theoretical Cloud Physics, JGU Mainz), we employ sensitivity experiments in two-way nested ICON simulations to explore the sensitivity of WCB ascent to the representation of individual microphysical processes in the ICON two-moment microphysics scheme. Our research with the focus on 'cloud-scale uncertainties' is embedded in the transregional collaborative research center 'Waves to Weather'.
