The method of reconstructing the global distribution of statistical parameters of internal gravity waves (IGWs) in the atmosphere has been tested using the data of amplitude fluctuation measurements of a radio signal in satellite radio occultation (RO) observations. In our previous work, for the chosen model of the spatial IGW spectrum, its relationship with the spectra of amplitude fluctuations was obtained, an algorithm for reconstructing the model parameters was developed, and the reconstruction errors were estimated. The reconstructed parameters of the vertical IGW spectrum are the external scale, which separates the unsaturated large-scale waves from saturated small-scale waves, and the structural characteristic, which determines the spectral amplitude of saturated waves. These parameters are used to calculate the variance of temperature fluctuations and the potential energy of the waves. This article presents the altitude–latitude distribution of IGW parameters in the stratosphere according to the measurements of the COSMIC experiment in 2011. The characteristic features of these distributions are noted, and the results are compared with the data of other measurements.

由无线电掩星信号幅度波动导出的大气内部重力波参数的纬度分布

已经使用卫星无线电掩星 (RO) 观测中无线电信号的幅度波动测量数据测试了重建大气中内部重力波 (IGW) 统计参数全球分布的方法。在我们之前的工作中，对于所选择的空间IGW光谱模型，获得了它与幅度波动光谱的关系，开发了一种重建模型参数的算法，并估计了重建误差。垂直IGW谱的重构参数是区分不饱和大尺度波和饱和小尺度波的外尺度和决定饱和波谱幅值的结构特征。这些参数用于计算温度波动的方差和波的势能。本文根据 2011 年 COSMIC 实验的测量结果，给出了平流层中 IGW 参数的高度-纬度分布。注意到这些分布的特征，并将结果与​​其他测量数据进行比较。
