From multiple rounds of thunderstorms between August 7 and August 12 in the Huntsville, AL area. Compared to storms in northern Illinois, the storms down here produce a much greater proportion of negative CG lightning with respect to total lightning activity. This is likely due to the more tropical airmass which favors a more classic "normal tripole" charge structure as opposed to the more complex/messy cloud charge structures that we see in the central/northern US.
Unfortunately there was a lightning fatality in northern Alabama from one of these rounds of storms.

Lightning information provided by Vaisala's National Lightning Detection Network (NLDN) through weather.us/lightning. Note that I only use this information to roughly estimate stroke intensity and distance, the data may be prone to error on my end and my work is not, and should not be considered to be, a formal evaluation of the NLDN's performance.
Thanks to Tom A. Warner and other lightning physicists and researchers who have helped me understand lightning processes explained in my videos. Tom has created a great resource for individuals interested in learning how lightning works.
