From: Quantifying gravity wave forcing using scale invariance

Spectral slopes and deduced zonal forcing by unresolved waves from simulation without parameterized gravity wave forcing. Downslope values of a power spectra of zonal, meridional, and vertical winds, b spectrum of vertical flux of zonal momentum, and c spectra of eastward and westward forcing at 75 km. d Zonal forcing by unresolved gravity waves deduced from the forcing by resolved gravity waves based on scale invariance. These are from the simulation without parameterized gravity wave forcing. Base 10 logarithmic scale is used in d
