Abstract [en]

A new model to determine the spectral velocity tensor in a stably stratified flow is proposed. This model is complementary to the Mann model as it solves the stratified inviscid Rapid Distortion Theory equations analytically, allowing for the determination of the single and two-point velocity spectra as well as the temperature-velocity cross-spectra. The model has been here calibrated and validated against field measurements conducted over a forested area with measurements up to 140 m, therefore covering a region of interest for wind-energy applications.
