PANAMA CITY, Fla. (WMBB) — Meteorologist Melissa Thomas talks thunderstorm phenomenon called blue jets, sprites, and elves. Yes these are legitimate meteorological terms. Very rare flashes of electromagnetic energy that occur above thunderstorms. Researchers are still studying exactly what causes them over big thunderstorms, because they don’t always happen. NASA pictures of blue jets and sprites are included in this segment, but not elves as they occur so very quickly, and require a certain type of camera to capture.
