Abstract

The results of studies of atmospheric dynamics in the altitude range of 60–130 km are presented based on measurements of the velocity of vertical plasma motion, the temperature and density of the neutral component, and the turbopause height. The measurements were carried via resonant scattering of radio waves by artificial periodic inhomogeneities of the ionospheric plasma. The method is based on ionospheric perturbation by powerful high-frequency radio emission, the creation of periodic inhomogeneities in the field of a standing wave, which forms upon reflection from the ionosphere of a powerful radio wave emitted into the zenith, and the location of inhomogeneities by test radio waves. The parameters of the neutral component, the turbulent velocity, and the height of the turbopause are determined from the relaxation time of the signal scattered by the inhomogeneities after the end of the ionospheric impact. The measurement of the phase of the scattered signal makes it possible to determine the rate of vertical plasma motion. The experiments were carried out on a SURA heating facility (56.15° N; 46.11° E). The paper presents and analyzes the time–altitude dependences of the vertical velocity and temperature, which are largely due to the propagation of atmospheric waves during various natural phenomena. The results of determination of the turbopause height and turbulent velocity are presented.

摘要

基于垂直等离子运动的速度，中性成分的温度和密度以及涡轮暂停高度的测量结果，给出了在60-130 km高度范围内的大气动力学研究结果。通过电离层等离子体的人工周期性不均匀性，通过无线电波的共振散射进行测量。该方法的基础是强大的高频无线电波对电离层的扰动，在驻波场中产生周期性的不均匀性（不均匀性的位置，不均匀性的位置，不均匀性的位置，不均匀性的位置）通过测试无线电波。中性成分的参数，湍流速度，涡轮暂停的高度和高度由电离层撞击结束后由于不均匀性而散射的信号的弛豫时间确定。散射信号的相位的测量使得可以确定垂直等离子体运动的速率。实验在SURA加热设备（56.15°N； 46.11°E）上进行。本文介绍并分析了垂直速度和温度的时空依赖性，这主要是由于各种自然现象期间大气波的传播所致。给出了确定涡轮暂停高度和湍流速度的结果。实验在SURA加热设备（56.15°N； 46.11°E）上进行。本文介绍并分析了垂直速度和温度的时空依赖性，这主要是由于各种自然现象期间大气波的传播所致。给出了确定涡轮暂停高度和湍流速度的结果。实验在SURA加热设备（56.15°N； 46.11°E）上进行。本文介绍并分析了垂直速度和温度的时空依赖性，这主要是由于各种自然现象期间大气波的传播所致。给出了确定涡轮暂停高度和湍流速度的结果。
