Context: Recently, ‘Bomb cyclone’ hit eastern US, which triggered transport chaos and power outages.

What is a Bomb Cyclone?

  • A bomb cyclone is a large, intense midaltitude storm that has low pressure at its center, weather fronts and an array of associated weather, from blizzards to severe thunderstorms to heavy precipitation.
  • Bomb cyclones put forecasters on high alert, because they can produce significant harmful impacts.

Reasons for the Formation:

  • This can happen when a cold air mass collides with a warm air mass, such as air over warm ocean waters. The formation of this rapidly strengthening weather system is a process called bombogenesis.
  • It occurs when a midlatitude cyclone rapidly intensifies, dropping at least 24 millibars over 24 hours.

Difference between Bomb Cyclone and a Hurricane

  • Hurricanes tend to form in tropical areas and are powered by warm seas. For this reason, they’re most common in summer or early fall, when seawater is warmest.
  • Bomb cyclones generally occur during colder months.
  • Hurricanes form in tropical waters, while bomb cyclones form over the northwestern Atlantic, northwestern Pacific and sometimes in the Mediterranean Sea.
