Numerical implementation of the uniform-shear model

Matlab implementation of the uniform shear model by Mann (1994)

Summary

The computation of the one-point spectra, co-spectra and coherence of turbulent wind is conducted using the uniform-shear model from Mann (1994) [1]. The goal is to describe the spatial structure of stationary homogeneous turbulence under a neutral atmospheric stratification using only 3 adjustable parameters.

Content

The present submission contains:

• The function MannTurb.m that computes the sheared spectral tensor
• The function MannCoherence that computes the wind co-coherence
• A LiveScript for the example file
• A data file GreatBeltSpectra.mat that contains the wind spectra from the Great belt bridge experiment for comparison with the computed spectra.

Any question, comment or suggestion is warmly welcomed.
