   • 1979, Kendrick Frazier, The Violent Face of Nature: Severe Phenomena and Natural Disasters‎, Morrow, →ISBN, page 97:

     A typical lightning bolt has an optical power of about 1 billion watts. The superbolt flashes radiate 100 billion to 10 trillion (10¹¹)-(10¹³) watts. They are quite rare.

   • 1981, Marta Kowalczyk, Lightning as a source of NOx in the troposphere:

     This low lightning rate is insufficient to affect the global NOx production, however it may cause local enhancement near Japan where most superbolts occur.

   • 2015, Derek M. Elsom, Lightning: Nature and Culture:

     In rare cases a positively charged giant 'superbolt' may discharge from the forward (or rear) anvil cloud to the negatively charged ground ahead of (or behind) the thunderstorm base.
