Mean vertical motions seen by radar wind profilers

Abstract

In gravity waves with downward phase propagation (upward energy propagation), the perturbations to the static stability and to the vertical velocity are negatively correlated. Statistical analysis of data from Flatland suggests that in the midtroposphere about 60% of the gravity wave energy is contained in waves with downward propagation of phase. The present model for w applies to the reflectivity from any refractive-index irregularities that can be treated as passive scalars, whether they are in the neutral atmospheric density, aerosol density, or plasma density and whether they arise from isotropic turbulence, anisotropic turbulence, Fresnel scattering, etc. -from Authors
