An article in the Journal of Geophysical Research ["Spatial and Temporal Distributions of US. of Winds and Wind Power at 80 m Derived from Measurements," (2003, vol. 108, pp. 10-1: 10-20)] considered wind speed at stations throughout the US. A Weibull distribution can be used to model the distribution of wind speeds at a given location. Every location is characterized by a particular shape and scale parameter. For a station at Amarillo, Texas, the mean wind speed at 80 m (the hub height of large wind turbines) in 2000 was 10.3 m/s with a standard deviation of 4.9 m/s. Determine the shape and scale parameters of a Weibull distri- bution with these properties.
