Analysis of Model Results for the Turning of the Wind and Related Momentum Fluxes in the Stable Boundary Layer [PDF]

open access: green, 2009
The turning of wind with height and the related cross-isobaric (ageostrophic) flow in the thermally stable stratified boundary layer is analysed from a variety of model results acquired in the first Global Energy and Water Cycle Experiment (GEWEX ...

Large-Eddy Simulation of Stably Stratified Atmospheric Boundary Layer Turbulence: A Scale-Dependent Dynamic Modeling Approach [PDF]

open access: bronze, 2006
A new tuning-free subgrid-scale model, termed `locally-averaged scale-dependent dynamic' (LASDD) model, is developed and implemented in large-eddy simulations (LESs) of stable boundary layers.

Stable Boundary Layer Issues

open access: green, 2012
Understanding and prediction of the stable atmospheric boundary layer is a challenging task. Many physical processes are relevant in the stable boundary layer, i.e. turbulence, radiation, land surface coupling, orographic turbulent and gravity wave drag, and land surface heterogeneity.

Diurnal evolution of negative atmospheric ions above the boreal forest: from ground level to the free troposphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
At SMEAR II research station in Hyytiälä, located in the Finnish boreal forest, the process of new particle formation and the role of ions has been investigated for almost 20 years near the ground and at canopy level.

Wake properties and power output of very large wind farms for different meteorological conditions and turbine spacings: a large-eddy simulation case study for the German Bight [PDF]

open access: yesWind Energy Science, 2022
Germany's expansion target for offshore wind power capacity of 40 GW by the year 2040 can only be reached if large portions of the Exclusive Economic Zone in the German Bight are equipped with wind farms.

Elucidating HONO formation mechanism and its essential contribution to OH during haze events

open access: yesnpj Climate and Atmospheric Science, 2023
Atmospheric nitrous acid (HONO) chemistry is of critical importance to air quality during polluted haze events, especially in China. However, current air quality models (such as WRF-CHEM, WRF-CMAQ, Box-MCM) generally underestimate the concentration of ...
