Sources of uncertainty for convective-scale predictability

Forecasting convective precipitation remains one of the key challenges in weather forecasting. The predictability of convective precipitation depends on many factors including uncertainties in the synoptic-scale flow, inaccuracies in the state and description of the atmosphere as well as of the underlying surface, and (...)

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...)

ACTRIS-D on new National Roadmap for Research Infrastructures

The Federal Ministery of Education and Research has included the enhancement of atmosphere observation infrastructures on its funding Roadmap. More in German...

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...
