windpowerlib.tools.estimate_turbulence_intensity

windpowerlib.tools.estimate_turbulence_intensity(height, roughness_length)[source]

Estimate turbulence intensity by the roughness length.

Parameters:

  • height (float) – Height above ground in m at which the turbulence intensity is calculated.

  • roughness_length (pandas.Series or numpy.array or float) – Roughness length.

Notes

The following equation is used [1]:

TI=\frac{1}{\ln\left(\frac{h}{z_\text{0}}\right)}

with:

TI: turbulence intensity, h: height, z_{0}: roughness length
