The table below contains the following parameters for each of the 239 stations in the US National Solar Radiation Data Base:
•Annual average wind speed, vave [m/s]
•Weibull k value, k
•One-hour autocorrelation factor, r1
You can also view histograms of these parameters.
Tip: The stations that take these measurements are not typically located so as to maximize the wind resource. Therefore, this data is likely to be conservative in terms of wind speed. Typically, wind turbines are sited on a ridgeline or other topographic feature to maximize average wind speeds. Also, this data is compiled from Typical Meteorological Year (TMY) data, which is largely based on solar data, not wind data. So these data do not necessarily represent a typical year of wind speeds.
