Scientific Research

Julian

The understanding of the atmospheric boundary layer processes over complex terrain is still a challenging open question. Numerical modelling has proven been a great tool to approach the problem, due to its flexibility and growing computer power in the last decades.

My research focuses on process analysis through the implementation of large eddy simulations and mesoscale numerical models. In addition, part of my time is devoted to exploring atmospheric dynamics with the aim of addressing air quality problems.

  • Hans Ertel Zentrum (HERZ): The Atmospheric Boundary Layer in Numerical Weather Prediction

    The Goethe University Frankfurt has established a new research group on boundary-layer meteorology at its Institute for Atmospheric and Environmental Sciences. The group is headed by a professor Juerg Schmidli. The group research addresses the representation of the atmospheric boundary layer (ABL) in numerical weather prediction, with a particular focus on the cloudy and complex-terrain boundary layer and with a specific application to the German met offige (Deutscher Wetterdienst - DWD) model Icosahedral Non hydrostatic (ICON).

    Subgrid-scale (SGS) models for the complex-terrain boundary layer are to be developed which take into account the impact of thermally driven flows, internal gravity waves and other effects of SGS orography. The work relies heavily on large-eddy simulation (LES) for idealized and realworld cases and on observational data from the HErZ field campaign planned in 2020. The improved treatment of the ABL in ICON is expected to lead to better predictions of local weather phenomena important for energy meteorology and high-impact weather.
