Mid-latitude cyclones drive most of the stormy weather in the continental U.S., the agency notes.

A process called bombogenesis can occur when a mid-latitude cyclone intensifies rapidly over a 24-hour period, dropping 적어도 24 millibars of atmospheric pressure.

일반적으로, a range in millibar change is around 10 ...에 15 in that same timeframe.

This can happen when a cold air mass collides with a warm air mass, like air over warm ocean waters.

The formation of the fast-strengthening weather system is bombogenesis, which generates the bomb cyclone.

The effects of the fast-developing low-pressure system include high and intense winds and blizzard and white-out conditions with heavy snow, in addition to rainfall on snow that can cause flooding.

It’s not unusual to get at least one storm per year and bombogenesis nor’easters occur frequently during the winter seasons.
