Please note most lightning signatures are terrain dependent,
and vary much across the nation and the world, so one
must look at local geography and orographic affects
as well as the type of general airmass, and type of
storms one sees in their local area and build their
databases based on this data. Here is some base
data for our study area:

The LIDIA Domain covers in Tennesee - Hardin, Wayne, and
Lawrence Counties. In Mississippi - Alcorn, Prentiss,
Itawamba, Tishomingo. In Alabama, Lauderdale, Colbert,
Franklin, Marion, Lawrence.

The average duration or lifetime of a severe thunderstorm in
the LIDIA Domain is 3.5 hours.

10 Flashes per square Kilometer (All Flashes).
Mean annual flash density is 5 per sq. km.

0 - 75 VA Large Peak amplitude is .05
Average Multiplicity is 2.0 (All Flashes)
Negative CG Flash multiplicity is 2.5 to higher than 10.
POS CG Flash multiplicity is 1.15 to 1.20

0 - 75 VA is 4.0 for -CG Flashes
-CG have a current around 23 KA on average.

60 days of Thunderstorm activity on average.
6 days of higher than normal lightning activity.

Most Lightning occurs between Noon and 6 pm.
The best time for lightning is between noon and 4 pm.
June, July and August are the best LTG months
6% - 10% of Lightning is POS CG.
