What is bomb cyclone
Bomb cyclones are usually used to refer to meteorological systems with rapidly decreasing air pressure. In North America, they are mainly formed by cold air meeting warm and humid air in the Atlantic Ocean.
According to the definition of American Meteorological system, if the air pressure is reduced by 24 HPA in 24 hours, about 2.37% of the standard atmospheric pressure, then this meteorological system can be called Bomb cyclone, because the rapid decrease of air pressure often brings about drastic weather changes and heavy rainfall. Meteorologists use the word bomb to describe the explosive force and destructive force of this meteorological system.
