- Measurements and implications of the relationship between lightning and terrestrial gamma ray flashes (2005, background): “The lightning charge moment change required to generate the observed TGFs has been estimated to be around 6000 C km [Lehtinen et al., 2001], which is well above the 500 C km charge moment changes observed in most sprite-associated lightning strokes [Hu et al., 2002].”
- Inverted-polarity electrical structures in thunderstorms in the Severe Thunderstorm Electrification and Precipitation Study (STEPS) (2005, background): “Huang et al. (1999) noted the key metric in sprite formation should be the magnitude of the CG lightning charge moment (Mq), the product of charge lowered to ground by a CG flash (C) and the height from which this occurs (Zq).”
