’Bombogenesis’: Blizzard Fueled By Dramatic Pressure Drop

While millions of Americans gear up for likely historic snowfall this week, they should also prepare for a blizzard of the latest meteorological buzzword: bombogenesis. In simple terms, bombogenesis is the equivalent of a "meteorological bomb," according to The Weather Channel’s Kevin Roth. It occurs when a storm’s area of lowest pressure experiences a rapid drop of more than 24 milibars in 24 hours. "This turns a routine storm into an intense storm very quickly," Roth told NBC News.
