A Baseline for the Predictability of U.S. Cloud‐to‐Ground Lightning [PDF]
Geophysical Research Letters, 2018 AbstractThe product of convective available potential energy and precipitation rate is used as a proxy for U.S. cloud‐to‐ground (CG) lightning. The proxy is computed from numerical weather prediction model outputs and thus provides a simple method for producing CG lightning threat forecasts.

Halos generated by negative cloud‐to‐ground lightning [PDF]
Geophysical Research Letters, 2007 The Imager for Sprites and Upper Atmospheric Lightning (ISUAL) on the FORMOSAT‐2 spacecraft observes Transient Luminous Events (TLE) like sprites, elves, and halos from space. We analyzed halos that were observed in Central America close enough to ELF/VLF receivers that allowed for the determination of the polarity of the parent lightning.
