Five major categories of information about severe storm sferics and severe storm characterizations are presented: (1) Statistical Descriptions of Lightning as a VLF Source; (2) Model Studies of Cloud and Sferic Behavior; (3) Hardward Developments; (4) Software Developments; and (5) Results of a Cumulus Cloud Magnetic Field Survey. It is concluded that VLF sferics has no intrinsic predictive content. However, sferic behavior is closely correlated with cloud development and vigor and thus has very high indicative content. A method for examining the electric current motions within a cumulus cloud by sensing the resulting magnetic field is shown to be feasible. (Author)
