| description |
A new method of obtaining power spectral distribution of gravity waves as a
function of ground-based horizontal phase speed and propagation direction
from airglow observations has recently been proposed. To explain gravity
wave power spectrum anisotropy, a new gravity wave transmission diagram was
developed in this study. Gravity wave transmissivity depends on the
existence of critical and turning levels for waves that are determined by
background horizontal wind distributions. Gravity wave transmission diagrams
for different horizontal wavelengths in simple background horizontal winds
with constant vertical shear indicate that the effects of the turning level
reflection are significant and strongly dependent on the horizontal
wavelength. |
