Biography

I am a research fellow in the Aerosol and Cloud Gropu lead by Paul Field at ICAS. In my research I use the Unified Model with the newly developed cloud-aerosol interacting microphysics (CASIM) module to investigate cloud-aerosol interactions for various cloud regimes ranging from Southern Ocean supercooled stratus clouds to convective clouds over the Southwestern Peninsula of the UK. My research interests are centred on understanding the relative impact of variations in the large- and meso-scale dynamics, aerosol fields and uncertainties in cloud microphysics representation for cloud formation, evolution and precipitation formation.

Before joining the University of Leeds, Annette Miltenberger was a PhD student at ETH Zurich in the Atmospheric Dynamics group lead by Heini Wernli. In her thesis she developed a novel module for the regional numerical weather model COSMO, which allows to calculate trajectories at a very high temporal resolution during the model integration. The Lagrangian perspective was then utilized to better understand the precipitation formation in stable orographic clouds and to investigate the non-dimensional numbers governing their precipitation efficiency. The high temporally resolved trajectories have been demonstrated to be a valuable tool for investigating cloud microphysical processes and diabatic heating in complex flows, including cirrus cloud formation and foehn flows.
