„Clouds and precipitation in midlatitude cyclones: new asymptotic models“

The systematic incorporation of moisture into models for large-scale atmospheric flow, like the well-established quasigeostrophic (QG) theory, presents many unique challenges. This is particularly apparent when the QG equations are connected to the planetary boundary layer, where the relative strength and character of moist processes change drastically.

In this talk, we first introduce the recent extension of the classical QG-Ekman model to a triple-deck boundary layer theory, featuring a novel intermediary layer called the diabatic layer (DL). We then discuss the crucial role of mesoscale dynamics in the parameterization of condensation and sketch their incorporation into the preexisting model equations.

The remainder of the talk will be devoted to practical implications: in particular, we want to discuss how an analysis of the resulting equations might contribute to our theoretical understanding of fronts.
