一类行进电离层扰动的特征可以部分解释为观测选择的结果，其中大气波提供基本扰动，而水磁共振提供选择。当通过与大气的水磁耦合产生电磁振荡的自然模式时，就会发生这种共振，并导致单独可观察到的电离层电子的运动增强。与观测的定量比较提供了比热比（γ ~ 1.1）和尺度高度（C2γg ~ 20 km）的估计值，这些值低于相关 F2 区域的预期值，但仍然是可能的，并且在数量级上肯定是有效的。
The characteristics of one class of travelling ionospheric disturbance may be partially explained as the result of an observational selection, in which an atmospheric wave provides the basic disturbance and a hydromagnetic resonance the selection. This resonance occurs when natural modes of electromagnetic oscillation are generated through hydromagnetio coupling with the atmosphere, and it results in an enhanced motion of the ionospheric electrons which are alone observable. The quantitative comparison with observation provides estimates for the specific heat ratio (γ ~ 1.1) and scale height (C2γg ~ 20 km), which are lower than the values expected for the F2-region concerned, but which are nevertheless possible and certainly valid in order of magnitude.
