Wind power density was calculated using hourly simulated wind speed, temperature, pressure, and relative humidity. Values for these variables were interpolated to desired heights from MM5 vertical levels using a cubic spline method. It is noted that relative humidity was used to account for air density dependency on moisture. Annual and three-monthly (DJF, MAM, JJA, and SON as sequential calendar months) mean wind power densities at a grid cell and height were derived from hourly data.
