When did this new meteorological phenomenon appear?
A bomb cyclone is a term coined to describe extreme low pressure and strong wind gusts originating from a bombogenesis, a real condition. The weather phenomenon brought a “bomb” threat to parts of North America. The meteorological term “bombogenesis” first appeared in 2005 by storm expert David Epstein in the journal Climatic Change. The term first appeared in popular media in 2013 by Epstein, The Weather Channel and Mother Nature Network, but the meteorological definition was only reinforced in 2014 by The Weather Channel. According to several research studies, 80% of bomb cyclones precede extreme heat waves.
How severe was the weather phenomenon?
Bomb cyclones can bring some of the worst weather a region can experience. They are particularly vulnerable to flooding, intense rainfall, higher-than-average snowfall or severe wind gusts, mainly in the Lower 48 states, where they are more likely to be produced in mid-latitude. The bomb cyclone that plowed its way through the eastern US coast on Monday was classified as an EF1 tornado with wind speeds of 100-110mph. High winds caused extensive power outages in two dozen states, and hours of slick travel ensued, especially on the roads of Washington, Maryland and Virginia.
Is this the first bomb cyclone in the US?
It was the first recorded event on the eastern seaboard. In 1994 the Canadian coast line was hit by its most destructive event on record, as a bomb cyclone created a devastating storm system known as the Great Pacific Storm. There have been other significant depressions, but none as severe as the Great Pacific Storm which killed nine people, causing widespread property damage in Hawaii.
Does the name “bomb cyclone” have a history in meteorology?
It does not. But Epstein made the claim to describe the weather phenomenon in 2005.
