My research delivers new quantitative understanding of dynamical, cloud and aerosol microphysical processes in the atmosphere not only for meteorological clouds but also for volcanic plumes. I apply this detailed process knowledge to a deeper understanding of the natural hazards, atmospheric circulation systems and the representation of these processes in numerical models.
My current projects include:
- Using Large Eddy Simulations to parameterise the Convective Cloud Field: Despite much effort the representation of clouds including convection, remains a major source of uncertainty in atmospheric models for climate and numerical weather prediction. The Convective Cloud Field Model is a novel approach to parmeterise convection that explicitly distinguishes between individual clouds and their interaction in an ensemble of clouds.
- Radar-supported Next-Generation Forecasting of Volcanic Ash Hazard: Explosive volcanic eruptions present a global hazard to health, the environment and the economy. We perform detailed simulations of volcanic plumes in order to understand the influence of processes such as particle aggregation on the plume development.
