Effects of sea surface temperature accuracy on offshore wind resource assessment using a mesoscale model
Abstract Offshore wind simulations were performed with the Weather Research and Forecasting (WRF) model driven by three different sea surface temperature (SST) datasets for Japanese coastal waters to investigate the effect of the SST accuracies on offshore wind simulations. First, the National Cente...
