Maps without a good legend tell very little. For example:
Notice the highest frequency of ground strikes is West Virginia; depending on the statistical ratio used. So is FL the lightning capitol of the world? The topmost world lightning maps puts FL somewhere around 5 or 8 in the world. But then that is not ground strikes. Central Africa, hands down, is the world capitol of lightning. Inodnesia is also dominant.
WV has some of the highest CG vs IC lightning strike. One reason offered was the unique geology of that region. Another placed PA with some of the highest numbers of lightning damage claims by dollar amount.
Best part of all these maps - lots of color. Sort of reminds me of ty-dye shirts.
