A bomb cyclone is basically a winter hurricane, and this storm has a pressure that’s equivalent to a Category 2 hurricane.
As a powerful storm slams the central U. S. on Wednesday, people have started calling it a “bomb cyclone.” Are they right?
Yes. The storm has officially undergone bombogenesis, the National Weather Service reported Wednesday, which means it can be called a bomb cyclone.
Bombogenesis occurs when a storm’s barometric pressure drops by 24 millibars – a millibar is a way of measuring pressure – in 24 hours. According to CNN meteorologist Brandon Miller, the storm pressure has “dropped 24 millibars in the last 18 hours. So it more than meets the criteria.
