This paper by Handel, Carlson, and Leitner discusses ball lightning with spiking and cold emission in the maser-caviton interaction, presented at the 2007 American Geophysical Union General Assembly in Acapulco. The research combines analysis of temporal energy fluctuations (spiking behavior) with electron field emission processes in the maser-caviton ball lightning model, explaining observed luminosity variations, electromagnetic pulse generation, and surface discharge phenomena associated with ball lightning encounters with conducting objects or ground.
