On the effect of the mean shear wind in the predicted "universal" spectral shape of the atmospheric variables

The Doppler shift undergone by a single quasi-sinusoidal wave in a constant, stratified, mean shear background atmosphere is analytically and numerically considered. This wave does not encounter critical levels for the elementary cases here considered. The idealized picture intends to illustrate the...
