Kazimrovsky et al seems to be mainly a catalogue of questions that still
need to be answered. The paper is available at
There are a few additional resources available on the web. See, for example:
Direct Coupling Between Lightning and the Mesosphere/Lower Ionosphere
Coupling and Energetics in the
Stratosphere-Mesosphere-Thermosphere-Ionosphere System by D. Rees, J.
Lastovicka, W. E. Ward (expensive from Amazon.com)
At a quick glance these seem to focus on VLF, and I saw no reference to
effects at higher frequency, but I'm no physicist.
