A bomb cyclone is a large, intense mid-latitude 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. A millibar measures atmospheric pressure.
👉How does a Bomb Cyclone differ from 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 because cyclones occur due to cold and warm air meeting. During the summer, there’s generally not
much cold air across the atmosphere; this means a bomb cyclone is much less likely to occur.
Hurricanes form in tropical waters, while bomb cyclones form over the northwestern Atlantic, northwestern Pacific and sometimes the Mediterranean Sea.
