A bomb cyclone, also known as bombogenesis, is a fast-developing storm that occurs when atmospheric pressure drops at least 24 millibars over a 24-hour period. This process of rapid intensification has a name: bombogenesis. When a cyclone “bombs,” or undergoes bombogenesis, this tells us that it has access to the optimal ingredients for strengthening, such as high amounts of heat, moisture, and rising air. Most cyclones don’t intensify rapidly in this way. Bomb cyclones put forecasters on high alert because they can produce significant harmful impacts. The hazards of a bomb cyclone can be multifaceted and vary based on the location and speed of the storm. The band of intense pressure can create heavy winds, blizzard conditions, heavy snow that can possibly reduce visibility, and rainfall. Heavy precipitation can also cause coastal flooding. A bomb cyclone can also cause a ripple effect of other weather events, such as sharp temperature drops.
