Stochastic Parameterization of Processes Leading to Convective Initiation in Kilometer-Scale Models

Predicting convective precipitation (e.g. typical summer thunderstorms) with numerical weather prediction models is limited by their ability to initiate convection. For this initiation small-scale processes in the atmospheric boundary layer are particularly important. (More...)

Predictability of Deep Convection
In this publication, we investigate the predictability of convection with the quasi-operational high-resolution ensemble weather forecasting system COSMO-KENDA in both idealized and real world scenarios. (More...)

Thermal 3D radiative transfer for non-rectangular model grids

Radiation drives weather and climate of our planet. Due to the high computational cost, radiative transfer is treated poorly in most atmospheric models. More...
