WRF Model Methodology for Offshore Wind Energy Applications

Table 5

Statistical metrics (MAE in m/s, ME in m/s, STD of the ME in m/s, and 𝑅) for the wind speed at 8 vertical levels (30–100 m), so as to evaluate the performance of four PBL schemes (YSU, MYJ, ACM2, and MYNN) at the 3 km WRF modelling domain.
