The term "bomb" has been around for at least 30 years, that I can remember, perhaps longer. While not particularly "scientific" sounding, it does have a pressure fall rate associated with it. I can't remember the exact value, something like 24 millibars in 24 hours, weighted by the sine of the latitude, or something like that. It is essentially a hole in the atmosphere and does occur fairly often. There is certainly more attention (i.e. advertising dollars) associated with weather events today that were just as common in the past. It is what it is.

I don't like their use of the word "bomb" and I think it was first used last year. Early spring is the time for the most tornados in the very place they are happening, but it usually follows a very warm day.
