Current work
My PhD project focuses on the dynamics and microphysics of snowfall in mountainuous and Antarctic environments.
The main research objectives are firstly to better characterise the occurrence of different microphysical processes (i.e. vapour deposition, aggregation, riming) in radar data. Secondly we aim to understand how synoptic and mesoscale meteorological conditions constrain the occurrence of these processes.
The analyses are based mainly on data from an X-band dual polarisation Doppler scanning radar and a W-band cloud profiler collected during field campaigns in South Korea during winter 2017/2018 and in Antarctica during the Austral Summer 2018/2019.

Atmospheric processes: from cloud to global scales
The main objective is to present important atmospheric processes from the local to global scales. The course will start with cloud processes, continue to synoptic phenomena like extratropical cyclones and fronts, to finally cover numerical modeling at the regional and global scales.
