TL;DR: The current model core of the PALM 6.0 model system is described and much effort was made to enhance the model with components needed for applications in urban environments, like fully interactive land surface and radiation schemes, chemistry, and an indoor model.

TL;DR: In this paper, the stably stratified atmospheric boundary layer (SABL) is taken an exceptional position as wake effects and thus loads on subsequent turbines are stronger, and the authors show the impact of the SABL on power production and wake effects (power deficits) in offshore wind farms by means of measurements as well as large-eddy simulations.

TL;DR: The New European Wind Atlas (NewA) as discussed by the authors is the final version of the wind atlas, which is based on a combination of the weather research and forecasting (WRF) model and the wind analysis and applications program (WAsP).

TL;DR: In this article, an optimal combination of model setup and parameterisations was found for simulating the wind field at turbine-relevant heights with the Weather Research and Forecasting (WRF) model.

TL;DR: In this paper, high-resolution large-eddy simulations of two German offshore wind farms are performed with the LES model PALM in which the turbines are parameterized with an actuator disk approach.
