Bomb Cyclone
  • The amount of pressure loss within the low-pressure mass must be at least 24 millibars in 24 hours to be considered a bomb cyclone.
  • As a result, the gradient between the two air masses, or pressure differential, increases quickly, strengthening the winds. Bombogenesis is the name given to this process of fast intensification.
  • A cyclonic effect is created by the earth's rotation and the wind's movement.
  • It is anticlockwise in the Northern Hemisphere, when viewed from above.
  • All of the elements for a bomb cyclone were present over the Great Lakes, as the meandering polar vortex collided with unusually warm air to the east.
  • As a severe storm weakened near the Great Lakes, it sparked blizzard conditions, including intense winds and snow, due to the rapid drop in atmospheric pressure.
  • From the Canadian Great Lakes to the Rio Grande at the Mexican border, there may be extreme weather.
