Head of the Working Group: Prof. Dr. Cedrick Ansorge

This research group is formed around the EU-funded project trainABL (“Turbulence-Resolving approaches to the  intermittently turbulent atmospheric boundary layer”). 

We use turbulence-resolving methods at the smallest scale in combination with observations and large-eddy simulation to eventually overcome the gap between high-resolution direct numerical simulation and the geophysical limit of high- Reynolds-number boundary layers.

Research Fields:

• Numerical Simulation of Turbulence (Direct Numerical Simulation, DNS and Large-Eddy Simulation, LES)

• Stably stratified Planetary Boundary Layers (extreme stratification)

• Maintenance and intermittency of turbulence in stratified conditions

• Turbulent mixing parameterizations

• Surface-Atmosphere Coupling

Research Focus: 

• transitional turbulence and large-scale intermittency
• boundary layers under extreme conditions
• unification of turbulence simulation approaches 
• bridging the gap between small-scale turbulence modelling, atmospheric observation and large-scale models 

Research Methods: 

• direction numerical simulation
• large-eddy simulation 
• scaling analysis
