A bombogenesis, aka "cyclone bomb," is used to describe an extreme drop in pressure of 24 millibars in 24 hours. These rapidly strengthening storms occur when a large temperature gradient is formed between a cold continental mass of air and warm sea-surface temperatures. These air masses mix to form what's called an "extratropical cyclone," with cold air at its core deriving energy from the mixing of hot and cold air masses around it.
As you might expect, these storms commonly happen along the East Coast. Nor'easters in particular are often formed through the process of bombogenesis.
