Dynamical Downscaling of Climate Change Impacts on Wind Energy Resources in the Contiguous United States by Using a Limited-Area Model with Scale-Selective Data Assimilation

Table 1

Classifying wind energy at 10 meters based on wind speed (m s⁻¹), wind power density (W m⁻²), and overall wind resource potential.

Wind power class	Resource potential	Wind speed (m s^−1)	Wind power density (W m^−2)
1	Marginal	<4.4	<100
2	Marginal	4.4–5.1	100–150
3	Fair	5.1–5.6	150–200
4	Good	5.6–6.0	200–250
5	Excellent	6.0–6.4	250–300
6	Outstanding	6.4–7.0	300–400
7	Superb	>7.0	>400
