Thunderstorm formation depends on environmental stability and the existence of electrification mechanisms. Because electrification mechanisms such as the ice-graupel collision process, described with the Relative Diffusional Growth Rate Theory, depends on convection for charge separation, and convection relates to Convective Available Potential Energy (CAPE), the relationship between CAPE and lightning is determined. A Spearman Rank Correlation revealed a small positive correlation between lightning and CAPE, and corresponding p-values indicate this correlation is significant. The evaluation of the relationship between CAPE and lightning lends meaningful insight into thunderstorm formation and electrification, providing an understanding that can enhance severe weather forecasting products.
