基于往返智能探测系统（RTISS），通过多阶结构函数分析和奇异性测量，获得了定量描述平流层中下层大气扰动特征的赫斯特指数和间歇性参数。根据三阶结构函数，将小尺度重力波分为三种状态：稳定、不稳定和伴有湍流。三阶结构函数随时间的变化反映了重力波的演化，同时也观察到了湍流的产生。本文定义了大气扰动强度参数RT，它包含波动扰动（H1）和随机不稳定性（C1）。认为RT比单独使用上述两种方法更能合理地反映大气扰动的特征。此外，通过获得18-24 km高度范围内平浮阶段的水平波数谱和上升、下降阶段的垂直波数谱，我们发现，当重力波活动在水平方向上显著增强时，下方的垂直波数谱振幅显著增大，其显示重力波活动对下方大气环境的显著影响。
Through multi-order structure function analysis and singularity measurement, the Hurst index and intermittent parameter are obtained to quantitatively describe the characteristics of atmospheric disturbance based on the round-trip intelligent sounding system (RTISS) in the lower-middle stratosphere. According to the third-order structure function, small-scale gravity waves are classified into three states: stable, unstable, and accompanied by turbulence. The evolution of gravity waves is reflected by the variation of the third-order structure function over time, and the generation of turbulence is also observed. The atmospheric disturbance intensity parameter RT is defined in this paper and contains both wave disturbance (H1) and random intermittency (C1). RT is considered to reflect the characteristics of atmospheric disturbance more reasonably than either of the above two alone. In addition, by obtaining the horizontal wavenumber spectrum from the flat-floating stage and the vertical wavenumber spectrum from the ascending and descending stages at the height range of 18–24 km, we found that when the gravity wave activity is significantly enhanced in the horizontal direction, the amplitude of the vertical wavenumber spectrum below is significantly larger, which shows a significant impact of gravity wave activity on the atmospheric environment below.
