Other AbstractThis study utilizes the vertical profiles of temperature with a high resolution of 10 mt.o examine spectral character of normalized temperature fluctuations in the 2.908.01 km and 14.6519.76 km altitude ranges and to compare them with model spectra.Six vertical wavenumber spectra of normalized temperature fluctuations in the troposphere and six vertical wavenumber spec-tra of normalized temperature fluctuations in the lower stratosphere are pr that mean spectral slopes in the wavenumber range of 9.8x10-a in the troposphere and about-2.2 in the lower stratosphere.The2.5 x esented. Results indicate 10-2m-1 are about-1.9two mean spectral slopes are di-verge significantly from the value of-3.0 predicted by current saturation models and from the valueof-2.4 predicted by a "universal" atmospheric spectrum model as well as are believed to be the shallowest slopes ever measured by balloon-borne radioson de soundings.Mean spectral amplitudes in the wavenumber range of 9.8 x 10--1,2.5x10-2111-1 are about 24 times in the troposphere and 5 times in the lower stratosphere larger than the predicted saturated spectral amplitudes.The two mean spectral amplitudes are also significantly different from the saturation models and those measurements in current literature.The larger spectral amplitudes, together with the shallowest slopes, show collectively that the observed temperature spectra do not obey current gravity wave saturation models and "universal" atmospheric spectrum model.
