The FLUXNET network with numerous eddy covariance stations distributed worldwide is an
important backbone for the study of ecosystem-atmosphere interactions. In order to provide …

The horizontal grid spacing of numerical weather prediction models keeps decreasing
towards the hectometric range. We perform limited‐area simulations with the Icosahedral …

The atmospheric boundary layer is particularly challenging to model in conditions of stable
stratification, which can be associated with intermittent or unsteady turbulence. We develop …

Monin–Obukhov similarity theory (MOST) is used in virtually all Earth System Models to
parametrize the near‐surface turbulent exchanges and mean variable profiles. Despite its …

Direct numerical simulations (DNS) of plane Couette flows over thermally heterogeneous
surfaces at bulk Reynolds number\(Re= 10^ 4\) and bulk Richardson number\(Ri= 0.25\) are …

This study assesses the accuracy of ansys fluent 19.2, a commonly employed general-
purpose finite volume solver, in the context of wall-modeled large-eddy simulation for …

Stochastic representations of model uncertainties are of great importance for the
performance of ensemble prediction systems (EPSs). The stochastically perturbed …

Field measurements in the atmospheric surface layer (ASL) are key to understanding
turbulent exchanges in the atmosphere, such as fluxes of mass, water vapor, and …

Observations acquired in the stable surface layer during two field experiments (The
Mountain Terrain Atmospheric Modeling and Observations Program and the Climate …

In this dissertation, different aspects of turbulent transport and thermally driven flows over
complex terrain are investigated. Two publications concentrate on the vertical heat and …
