Characteristics of Lightning Within Electrified Snowfall Events Using Lightning Mapping Arrays [PDF]

Journal of Geophysical Research: Atmospheres, 2018
AbstractThis study examined 34 lightning flashes within four separate thundersnow events derived from lightning mapping arrays (LMAs) in northern Alabama, central Oklahoma, and Washington DC. The goals were to characterize the in‐cloud component of each lightning flash, as well as the correspondence between the LMA observations and lightning data taken
