Gravity-Wave Parameters in the Lower Stratosphere
R. A. Vincent, S. J. Allen and S. D. Eckermann
Abstract
Observations made in the lower stratosphere with high-resolution radiosondes
routinely launched from Macquarie Island are used to study parameters
important in gravity-wave parameterization schemes. The combination of
horizontal wind and temperature data allow wave amplitudes and direction
of horizontal propagation to be determined. Significant enchancements in
wave energy are found to occur near the inertial frequency and there is
appreciable directional anisotropy, especially in winter. Estimates of
vertical fluxes of horizontal momentum are made from the covariances between
the wind and temperature perturbations.
