Monin-Obukhov similarity theory (MOST) forms the basis for parametrizations of turbulent
exchange in virtually all numerical models of atmospheric flows. Yet, its limitations to flat and …

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 …

The vertical structure of the observed stable boundary layer often deviates substantially from
textbook profiles. Even over flat homogeneous surfaces, the turbulence may not be …

Turbulence in very stable boundary layers is typically unsteady and intermittent. The study
implements a stochastic modeling approach to represent unsteady mixing possibly …

Data collected by 12 sonic anemometers over the Plaine Morte Glacier (Swiss Alps) during
the Snow Horizontal Arrays Turbulence Study are used to investigate sources of anisotropy …

Small-scale processes in atmospheric boundary layers are typically not resolved due to cost
constraints but modeled based on physical relations with the resolved scales, neglecting …

Time integration of the unsteady Reynolds-averaged Navier–Stokes (URANS) equations is
the principal approach used in numerical weather prediction. This approach represents a …

This study examines the spatial variability of the nocturnal wind field using eight networks of
surface observations ranging in horizontal width from 500 m to 65 km. The wind field is …

A single-column model is used to investigate regime transitions within the stably stratified
atmospheric boundary layer, focusing on the role of small-scale fluctuations in wind and …

We examine measurements in the very stable boundary layer using tower data and a
network of flux stations in the Shallow Cold Pool experiment. Submeso motions in the very …
