Bomb Cyclone winter storm explained

One of the more major meteorological occurrences reported in recent times is the bomb cyclone. People all over the East Coast were given ample warning regarding this development but what they experienced was something no one saw coming as entire cities froze.

Bomb cyclones refer to bombogenesis, a meteorological phenomenon that occurs when a storm’s minimum central pressure goes down by at least 24 millibars within 24 hours. Although bomb cyclones are supposed to be common in the fall and winter in the East Coast, they have greatly exceeded the intensification rate, almost doubling it. 

These hurricanes become stronger due to the lower air pressure. The rapid pressure drop draws air into the storm’s circulation. As the air spirals inward toward the center, rises, and exits to the top, the further the storm grows. Drops in air pressure also cause extreme wind conditions. 

Bomb cyclones bring heavy, wet snow and powerful winds. This combination can easily cause power outages. What makes bomb cyclones more worrisome is the fact that they can turn small clouds into massive storms within 24 hours. They are supposedly rare, but they are becoming a common occurrence these days due to global warming.
