: Research identifies unique "bluish-green" light-emitting features in specific materials, such as barium aluminate crystals doped with Europium (Eu2+), which can be tuned based on solvent polarity. : They act as a thermal seal, blocking

: Severe thunderstorms and supercells can exhibit a "bluish-green" glow. This is caused by sunlight reflecting through heavy precipitation, often indicating the presence of large hail rather than being a direct indicator of a tornado. : Severe thunderstorms and supercells can exhibit a
