Diurnal variation of mountain waves [PDF]

open access: yes, 2006
Mountain waves could be modified as the boundary layer varies between stable and convective. However case studies show mountain waves day and night, and above e.g. convective rolls with precipitation lines over mountains.

Exchange Processes in the Atmospheric Boundary Layer Over Mountainous Terrain

open access: yesAtmosphere, 2018
The exchange of heat, momentum, and mass in the atmosphere over mountainous terrain is controlled by synoptic-scale dynamics, thermally driven mesoscale circulations, and turbulence.

Modeling of turbulent transport in the surface layer [PDF]

open access: yes
The turbulence equations as written by Donaldson using the method of invariant modeling have been applied to the following limiting cases of the surface or constant flux layer of the planetary boundary layer: (1) Neutrally stable; (2) stable (above ...

Spectral stability of noncharacteristic isentropic Navier-Stokes boundary layers

open access: yes, 2007
Building on work of Barker, Humpherys, Lafitte, Rudd, and Zumbrun in the shock wave case, we study stability of compressive, or "shock-like", boundary layers of the isentropic compressible Navier-Stokes equations with gamma-law pressure by a combination ...

Longitudinal vortices in a transitioning boundary layer [PDF]

open access: yes
Naturally occurring spanwise variations of the streamwise velocity component, characteristic of longitudinal vortices embedded in a transitioning boundary layer were explored using hot-wire anemometers.

Evolution of an atmospheric boundary layer at a tropical semi-arid station, Anand during boreal summer month of May - A case study [PDF]

open access: yes, 2000
The evolution of an Atmospheric Boundary Layer (ABL) over a semi-arid land station, Anand, (22°35â²N, 72°55â²E, 45.1 m asl) in India, during the summer month of May, is examined using surface meteorological and radiosonde temperature and humidity data ...

The role of the asymmetric Ekman dissipation term on the energetics of the two-layer quasi-geostrophic model [PDF]

open access: yes, 2020
In the two-layer quasi-geostrophic model, the friction between the flow at the lower layer and the surface boundary layer, placed beneath the lower layer, is modeled by the Ekman term, which is a linear dissipation term with respect to the horizontal ...

Stable Boundary Layer Education (STABLE) Final Campaign Summary

open access: yes, 2016
The properties of, and the processes that occur in, the nocturnal stable boundary layer are not well understood, making it difficult to represent adequately in numerical models. The nocturnal boundary layer often is characterized by a temperature inversion and, in the Southern Great Plains region, a low-level jet.

A note on sodar return signals in the stable atmospheric boundary layer

open access: yesMeteorologische Zeitschrift, 2009
A problem concerning the reliability of the determination of temperature structure parameter C2T with the help of sodar is considered. The results of comparisons between remote and in situ measurements of C2T in the atmospheric boundary layer (ABL) are ...
