Information

This model calculates the wind velocity at the location as a function of the height over ground. The equation is based on Gash (1991). The model computes the wind velocity vLoc as

vLoc = vRef * (h / hRef)n

where vRef is the wind velocity at the reference height, h is the height over ground, hRef is the reference height, and n is the height exponent for wind calculation.
