A13C-01: Contrasts between mesoscale and large-eddy simulations of wind farms: under-resolved gradients, slow wake recovery, and fast turbulence decay with mesoscale wind farm parameterizations (invited)
To predict energy from wind farms, we need to accurately represent wind farm wakes in weather models. We compare finely-resolved simulations to coarser weather-scale simulations and identify inaccuracies in the weather-scale representation. These errors arise because the weather-scale models cannot represent the sharp spatial gradients in wind speed and turbulence that occur at finer scales. This work suggests where we should put scientific emphasis for improving wake models for weather and climate forecasting.
