The bomb cyclone swept has through the US Great Plains resulting in blizzard conditions, hurricane-like winds, snow and heavy rain and subsequent flooding.
Bomb Cyclone or Bombogenesis
Bomb Cyclone or bombogenesis refer to a rapidly intensifying area of low-pressure winter storm when there is a pressure drop by at least 24 millibars in 24 hours. The decrease of the pressure intensifies the storm. This pressure drop intensification and subsequent winter storms result in strong winds, beach erosion and coastal flooding, especially with high tide.
Bombogenesis storm can be tropical or non-tropical and proximity to a large body of water, particularly an ocean, during cold months contributes to the creation of a bomb cyclone.
Bomb Cyclone is caused by a collision of warm air and cold air which develop into rotating storm-like pattern and lead to an explosive deepening of pressure. Worldwide about 40 to 50 ‘bomb cyclones brew each year.
