“…These internal waves are oscillations in the atmosphere or ocean that are supported by buoyancy and pressure forces, and also by the from rocket profiles are presented, and the radar balloon observations of Endlich, Singleton and Kaufman (1969)). Thus, the attention of meteorologists and aeronomists has historically been directed toward observing the vertical structure of the atmospheric wind field.…”

“…A variety of observational techniques have been used to study mesoscale fluctuations in different atmospheric regions, including Jimsphere balloon observations (Endlich et al, 1969), MST and MU radar measurements (Fritts and Chou, 1987;Tsuda et al, 1989); rocket smoke trail observations (Dewan et al, 1984), and lidar measurements (Senft and Gardner, 1991;Senft et al, 1993). These observational studies have revealed a considerable degree of universality of spectral shape and consistency with predictions of various saturation models.…”

Abstract. Vertical temperature profiles with a height resolution of 10 m have been measured in the troposphere and lower stratosphere during March and April 2003 over the Beijing Meteorological Observatory. This resolution allows us to study temperature spectra up to higher wave numbers than many published papers. Our purposes in this study are to examine the spectral character of normalized temperature fluctuations in the 2.90-8.01 km (troposphere) and 14.65-19.76 km (lower stratosphere) altitude ranges and to compare them with model spectra. Vertical wave number spectra of six temperature profiles are presented. Results indicate that mean spectral slopes are about −1.9 in the troposphere and −2.2 in the lower stratosphere, which is believed to be the shallowest slopes ever measured by balloonborne radiosonde soundings. Mean spectral amplitudes at m=1/(100 m) are about 17 times larger in the troposphere and 4 times larger in the lower stratosphere than the predicted saturated spectral amplitudes. These results show that the observed temperature spectra do not obey current gravity wave saturation models, the "universal" atmospheric spectrum model, or the wind-shifting model, in both slope and amplitude.

“…The amplitudes at lowest wave number are reduced due to filtering effect of removing a linear background and those at the highest wave numbers are enhanced due to noise and spectral aliasing (Nastrom et al, 1997). Dewan and Good (1986) examined the slopes reported by different workers (Dewan et al, 1984;Endlich et al, 1969;Rosenberg et al, 1974) and depending on their wavelength ranges recommended that the slope over 1 km-200 m can possibly be regarded as the more valid slope. We find from our observations ( Fig.…”
