R.W. Armstrong and J.G. Gle

Abstract

Damage from severe storms, particularly those involving significant lightning is increasing in the US. and abroad; and, increasingly, focus is on an electrical role for lightning in intra-cloud (IC) tornadogenesis. In the present report, emphasis is given to severe storm observations and especially to model descriptions relating to the subject.
