Short summary

This paper details observed connections between dense, transient layers within the lower ionosphere (sporadic E) and both meteor activity and irregularities higher in the ionosphere. The coupling between these layers and wavelike disturbances in the middle ionosphere seems to be shorted out when extremely dense “clouds” are present, which possible disrupt the stability of the layers.
