Resumen:
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 "zeroth
order" effect of a mean shear wind profile on the resulting
shape of temperature and wind spectra. The trial
of different vertical shear structures suggests that only
the linear or quasilinear wind profiles are able to reproduce
adequately the experimental spectral slopes. For
a linear shear and different incident wavelengths, slope
values near to-3 are found and the calculated spectra
close resemble those observed from atmospheric data.
