An archaic or rare term potentially related to thunder; a historical or scientific name that appears in old texts about weather or atmospheric phenomena.
From Greek 'bronte' (thunder). This appears to be a learned or scientific coinage from the Enlightenment era when scholars created Latin/Greek terms for natural phenomena.
The ancient Greeks were so obsessed with thunder they created a whole family of words: brontophobia (fear of thunder), brontograph (thunder recorder), and bronteon—it's like they couldn't stop talking about storms!
