Ventilation of a Mid-Size City under Stable Boundary Layer Conditions: A Simulation Using the LES Model PALM

open access: yesAtmosphere, 2021
City centers have to cope with an increasing amount of air pollution. The supply of fresh air is crucial yet difficult to ensure, especially under stable conditions of the atmospheric boundary layer.

Global stability of swept flow around a parabolic body: Features of the global spectrum [PDF]

open access: yes, 2011
International audienceThe global temporal stability of three-dimensional compressible flow about a yawed parabolic body of infinite span is investigated using an iterative eigenvalue technique in combination with direct numerical simulations.

Lidar Studies of Wind Turbulence in the Stable Atmospheric Boundary Layer

open access: yesRemote Sensing, 2018
The kinetic energy of turbulence, the dissipation rate of turbulent energy, and the integral scale of turbulence in the stable atmospheric boundary layer at the location heights of low-level jets (LLJs) have been measured with a coherent Doppler light ...

Assessment of Regional Climate Model Simulations of the Katabatic Boundary Layer Structure over Greenland

open access: yesAtmosphere, 2020
The parameterization of the boundary layer is a challenge for regional climate models of the Arctic. In particular, the stable boundary layer (SBL) over Greenland, being the main driver for substantial katabatic winds over the slopes, is simulated ...

Statistical investigations of flow structures in different regimes of the stable boundary layer [PDF]

open access: yes, 2019
A combination of methods originating from non-stationary timeseries analysis is applied to two datasets of near surface turbulence in order to gain insights on the non-stationary enhancement mechanism of intermittent turbulence in the stable atmospheric ...

An unstable superfluid Stewartson layer in a differentially rotating neutron star [PDF]

open access: yes, 2009
Experimental and numerical evidence is reviewed for the existence of a Stewartson layer in spherical Couette flow at small Ekman and Rossby numbers ($\Ek \lsim 10^{-3}$, $\Ro \lsim 10^{-2}$), the relevant hydrodynamic regime in the superfluid outer core ...

TURBULENCE STRUCTURES ACROSS LAYERS IN STABLE BOUNDARY LAYER

open access: yes, 2022
The stable atmospheric boundary layer (SBL), most often occurring at night and with the presence of a vertical temperature inversion, is characterized by very low levels of turbulence. Consequently, pollutants released from the surface are mainly trapped within the SBL, causing adverse effect on human health. Compared to the daytime convective boundary
