Trade wind cloud evolution observed by polarization radar: relationship to aerosol characteristics
One of the classical unsolved problems in cloud physics is the explanation of the observed short time between initial cloud formation and the onset of precipitation in warm clouds. Although a time interval of about 20 minutes is often quoted for initiation of warm rainfall, few field observations …

Gas distribution, star formation and giant molecular cloud evolution in nearby spiral galaxies
… galactic disk to the size of the Giant Molecular Clouds (GMCs). Differences in the shape and width of global CO and HI spectra of resolved disks of spiral galaxies are systematically investigated using a nearby sample for which high-resolution CO and HI maps are available. I find that CO line …

Revisiting the importance of a Southern Ocean pattern effect
… (2000) (SM00) argued that Southern Ocean clouds set the evolution of global radiative feedbacks in time and hence, determine climate sensitivity. We revisit their argument in current generation climate models: We quantify the time evolution of local atmospheric stability, clouds, and their …

On the role of natural laboratories and natural experiments in elucidating cloud-aerosol-climate interactions: A story of ships, smoke, and shutdowns
… in how airborne particles (aerosol) influence cloud reflectivity hinder our understanding of anthropogenic climate change. The study of aerosol-cloud interactions (ACI) is complicated by the difficulty of disentangling aerosol effects from other phenomena like meteorological variability. …

High-Resolution Modelling of Surface-Atmosphere Interactions and Convection Development at Nam Co Lake, Tibetan Plateau
… water resources, but also have influence on the evolution of the monsoon system and climate. High-resolution, numerical atmospheric models with a fully coupled surface model are a valuable tool for the systematic investigation of surface-atmosphere interactions. Nam Co Lake, located at the …

Airborne lidar observations of tropospheric arctic clouds
… sensitive to climate changes. The influence of clouds on the radiation budget is substantial, but difficult to quantify and parameterize in models. In the framework of the PhD, elastic backscatter and depolarization lidar observations of Arctic clouds were performed during the international …

Investigation of the positive interaction between the primary and secondary circulation and the roles of different types of precipitation in tropical cyclone formation
… through analyses of satellite data and cloud-representing numerical model simulations. Previous studies have emphasized the importance of the positive feedback between the ocean surface heat fluxes and the primary circulation, but our analyses based on high-resolution numerical model …
