Observational Evidence of a Saturated Gravity Wave Spectrum in the Troposphere and Lower Stratosphere

摘要: Abstract Radial velocity and temperature data obtained at the MU Radar Observatory during October November 1986 are used to examine character of motion spectrum in troposphere lower stratosphere. It is found that dominated by low-frequency gravity waves with an upward sense propagation stratosphere both downward troposphere. Vertical wavenumber spectra consistency saturated proposed Smith et al. Results indicate excellent agreement observed predicted amplitude slope. area-preserving form reveal a dominant vertical wavelength ∼2.5 km, systematic variations energy density scale time, between temporal variance. Taken together, our re...
