Abstract—

A new method has been developed for determining the characteristics of internal atmospheric waves based on the use of inclined sporadic E-layers of Earth’s ionosphere as a detector. The method is based on the fact that an internal wave propagating through an initially horizontal sporadic E-layercauses rotation of the plasma density gradient in the direction of the wave vecto which leads to the establishment of a layer ionization plane parallel to the phase wave front. The developed method allows us to study the relationship between small-scale internal waves and sporadic E-layers in Earth’s ionosphere and significantly expands the capabilities of traditional radio occultation monitoring of the atmosphere. It was found that the studied internal atmospheric waves have periods from 35 to 46 min and vertical phase velocities from 1.2 to 2.0 m/s which is in good agreement with the results of independent experiments and modeling data for sporadic E-structures at an altitude of ~100 km in Earth’s polar cap.

倾斜的零星电子层与地球电离层小规模大气波的关联

摘要—

基于使用地球电离层的零星倾斜E层作为探测器，已经开发出一种确定内部大气波特征的新方法。该方法基于以下事实：在初始水平的零星E层中传播的内部波会导致等离子体密度梯度沿波vecto方向旋转，从而导致建立平行于相波前的层电离平面。发达的方法使我们能够研究小尺度内波与零星E之间的关系。层在地球电离层中的分布，并大大扩展了传统的大气无线电掩星监测功能。发现研究的内部大气波周期为35〜46min，垂直相速度为1.2〜2.0m / s，与独立实验的结果和零高度零星E结构的建模数据吻合良好。距离地球极地约100公里。
