Numerical investigations into the idealized diurnal cycle of atmospheric boundary layer and its impact on wind turbine's power performance
TLDR
In this paper, wind characteristics in different regimes occurring throughout the idealized diurnal cycle and its impact on wind turbine's power performance are investigated systematically by means of large-eddy simulation (LES), and blade element momentum method (BEM), respectively.About:

Atmospheric Stability Affects Wind Turbine Power Collection
Sonia Wharton,Julie K. Lundquist +1 more
TL;DR: In this paper, the authors examined turbine power generation data, segregated by atmospheric stability, in order to investigate power performance dependences at a West Coast North American wind farm and found that the power generated at a given wind speed is higher under stable conditions and lower under strongly convective conditions.

Identifying the effect of climate change on desertification in northern China via trend analysis of potential evapotranspiration and precipitation
TL;DR: Li et al. as mentioned in this paper examined the relationship between desertification and climate change indicators for different time periods across northern China and found that climate change was the primary or one of drivers of desertification reversion in the northeastern and northwestern regions of China between 1975 and 1990.

Coupling Mesoscale Budget Components to Large-Eddy Simulations for Wind-Energy Applications
TL;DR: In this paper, the authors couple mesoscale model outputs to a large-eddy simulation solver by averaging momentum and temperature budget components from the Weather Research and Forecasting model to the governing equations of the Simulator fOr Wind Farm Applications model.

Review of atmospheric stability estimations for wind power applications
TL;DR: In this article , the authors systematically review the different parameters for estimating atmospheric stability and the criteria for classifying this stability, and the effect of atmospheric stability in wind power areas (wind profile, energy production, and wake) are discussed.

An Introduction to Boundary Layer Meteorology
TL;DR: In this article, the boundary layer is defined as the boundary of a boundary layer, and the spectral gap is used to measure the spectral properties of the boundary layers of a turbulent flow.

Numerical Investigation of Neutral and Unstable Planetary Boundary Layers
TL;DR: In this article, numerical integrations are presented for a neutrally stratified planetary boundary layer containing a passive scalar, and for three unstable cases with upward heat flux, assuming the air is assumed unsaturated.

A Comparison of Shear- and Buoyancy-Driven Planetary Boundary Layer Flows
Chin-Hoh Moeng,Peter P. Sullivan +1 more
TL;DR: In this article, four large-eddy simulations (LESs) spanning the shear and buoyancy flow regimes were generated; two correspond to the extreme cases of shear, while the other two represent intermediate PBLs where both forces are important.

A numerical study of the effects of atmospheric and wake turbulence on wind turbine dynamics
TL;DR: In this paper, the effects of atmospheric stability and surface roughness on wind turbine dynamics have been studied, and the authors used large-eddy simulation to create atmospheric winds and compute the wind turbine flows, and modeled the wind turbines as revolving and flexible actuator lines coupled to a wind turbine structural and system dynamic model.
