Abstract: In recent years, the challenge to systematically incorporate cloud formation and rain production into established mathematical models for weather systems has received increased attention. Moisture in the atmosphere plays a role on a large variety of length and timescales; furthermore, moist processes greatly vary in both intensity and character with altitude. Therefore, both boundary layer theory and the technique of multiple scales are important assets in tackling reduced dynamical models for cloudy air.
In this talk, we will take a look at precipitating quasi-geostrophic (PQG) models, as well as a triple-deck boundary layer theory that introduces the novel diabatic layer. We will also sketch current developments that refine PQG by interaction with dynamics on smaller scales. The focus of the presentation will consistently stay on the interplay between physical demands and formal mathematical techniques that is fundamental to the craft of modeling.

The seminars take place in hybrid form (in person and also on Zoom). The Zoom link is sent per email through the SFB Newsletter (normally sent either on Friday or during the weekend).
