Statistical and Spectral Analysis of Wind Characteristics Relevant to Wind Energy Assessment Using Tower Measurements in Complex Terrain

Table 3

The Weibull parameters and wind characteristics derived from the Weibull distribution. Monthly values are for the 2003–2008 composite datasets for the 50 m towers and for 2007-2008 for the 80 m tower.
