Turbulence spectral characteristics of surface boundary layer

A spectral analysis from wind tunnel and near-neutral atmosphere data was realized. The measurement spectra are compared with von Kármán and Kaimal expressions and a complementary evaluation based on the previous work of Arbage and Degrazia et al. was realized. A comparison of the vertical component...
