To help guide method selection in practice, this study compared three approaches using the Weather Research and Forecasting (WRF) model with a 100 m grid: observation nudging (NDG), temporal correction (TC), and the directional extrapolation method (DE). WRF simulations without on-site measurement data and direct application of onshore measurements were also evaluated as reference methods, using measurement data from four nearshore sites in Japan.

TC, which corrects simulated winds using wind vector errors at the reference point at each time step, achieved the lowest mean wind speed bias and the smallest standard deviation of bias across the evaluated cases. It also better reproduced horizontal wind speed differences between reference and target points. NDG improved the reproduction of temporal variations compared with the uncorrected WRF simulation, while DE had limitations in reproducing temporal variations in horizontal wind speed differences. These findings support the use of TC for practical nearshore wind resource assessment.
