AccuWeather explains the term "bombogenesis."

You may have seen this week's storm described using the terms "bombogenesis" and "bomb cyclone."

Bombogenesis happens when "a midlatitude cyclone rapidly intensifies, dropping at least 24 millibars over 24 hours," according to NOAA. This extreme and rapid change in pressure forms a very strong storm, a so-called "bomb cyclone."

Bomb Cyclone is not an official term. Meteorologists and scientist use "bombogenesis."

According to AccuWeather, these storms occur most commonly off the east coast and the recipe for it to form is "cold air along the land, warm air over the water."

Bomb cyclones happen almost every winter. This week's storm will make travel nearly impossible in parts of the East Coast.
