Poster Presentation
Atmospheric stability is an important metric in wind resource assessment to understand horizontal and vertical wind flow variation across a site as well to understand how efficiently a wind turbine converts energy from the wind to mechanical energy. Measures of atmospheric stability are commonly used as inputs to wind flow models, wind farm wake models, and turbine performance models. A spatial and temporal climatology of low-level atmospheric stability will be presented based on historical radionsonde observations around the U.S. Analysis of the seasonal profiles of atmospheric stability will also be presented. Given radiosonde observations are taken twice daily, an analysis of the difference between daytime and nocturnal atmospheric stability profiles will also be presented.
