About

I am an atmospheric scientist at the Institute for Atmospheric Physics of JGU Mainz. I received my Ph.D. in meteorology in 2013 at University Mainz while working at the Max Planck Institute for Chemistry. My primary research is about dynamics on the synoptic- and meso-scale and consequences for constituent transport in the atmosphere. In particular I am interested in situations where transport occurs across so-called transport barriers.
One of these transport barriers is the tropopause, i.e., the barrier between the well-mixed troposphere and the rather stably stratified stratosphere. In mid-latitudes such cross tropopause exchange occurs to a large degree in relation to baroclinic wave dynamics. These rather large scale phenomena on the planetary and synoptic scale are accompanied by meso-scale features such as gravity waves and cloud occurrence at the tropopause which alter the tropopause structure and in some cases foster exchange. I study the underlying processes with a hierarchy of numerical models, from regional, idealized to global, realistic models. More so, I use Lagrangian analysis methods (e.g., trajectory calculations), forecast, analysis, and reanalysis data in conjunction with high resolution air borne measurements to identify and constrain processes leading to exchange between tropospheric and stratospheric air.
Another transport barrier that I am currently interested in is the so-called polar dome. This feature emerges close to the surface in the High Arctic, most dominantly during winter and spring. This barrier separates the High Arctic from the mid-latitudes but is under special circumstances permeable, thus providing the opportunity for mid-latitude emissions to enter into the High Arctic. These events then have a local impact on air quality but the underlying dynamics are also of relevance for the climate in the Arctic.
