Longitudinal statistics of plasma bubbles: Possible tropospheric influence

Abstract

The assumption about the possible influence of a tropospheric source on the nature of the longitudinal statistics variation (relative frequency of observation) of plasma bubbles determined by the He⁺ density in the upper ionosphere altitudes is tested. To do this, the statistics are comparatively analyzed with a number of characteristics of the ionosphere and thermosphere, the longitudinal changes of which can be related to the DE3 tidal wave generated in the troposphere. Evidence of the possible influence of the troposphere on the longitudinal statistics of plasma bubbles has been obtained. Based on qualitative analysis, it was found that the thermospheric winds modulated by the DE3 tidal wave can link these statistics with processes in the troposphere.
