No, it’s not.

It’s a term meteorologists have been using for decades. It describes a certain progression of a low pressure system were a storm intensifies rapidly. It tells meteorologists in very few words a lot of information on the storm and what to expect from it.

Explosive cyclogenesis aka Bomb Cyclone
https://en.wikipedia.org/wiki/Explosive_cyclogenesis

“Explosive cyclogenesis (also referred to as a weather bomb,[1][2][3] meteorological bomb,[4] explosive development,[1] bomb cyclone,[5][6] or bombogenesis[7][8][9]) is the rapid deepening of an extratropical cyclonic low-pressure area. The change in pressure needed to classify something as explosive cyclogenesis is latitude dependent.

For example, at 60° latitude, explosive cyclogenesis occurs if the central pressure decreases by 24 millibars (0.71 inHg) or more in 24 hours.[10][11] This is a predominantly maritime, winter event,[10][12] but also occurs in continental settings.[13][14]

This process is the extratropical equivalent of the tropical rapid deepening. Although their cyclogenesis is entirely different from that of tropical cyclones, bomb cyclones can produce winds of 74 to 95 mph (120 to 155 km/h), the same order as the first categories of the Saffir–Simpson scale, and yield heavy precipitation. Even though only a minority of bomb cyclones become this strong, some weaker ones can also cause significant damage.”

The global cooling cult switched to the global warming cult in the 1990s.

“It’s a term meteorologists have been using for decades”

And... it’s in the NWS glossary

I guess all of my years of meteorology training and practical application were wasted. I never heard of a polar vortex, a bomb cyclone, or an atmospheric river until Al Gore’s propaganda movie Inconvenient Truth. The movie is probably required classroom material in today’s meteorology courses, J School, and weatherman acting classes.

We did, however, use the term Mid Latitude Migrating Frontal Cyclone.

But not TV weathermen.

I saw a TV report yesterday that was calling for excessivestorm possibilities from Southern Oregon all the way down the California coast :
extremely damaging high winds,
calling for 15 - 20 inches of rain
and 3-4 inches of snow in the highlands.

The expected river of atmospheric pressure when added to a (West coast)cyclone/ hurricane (East coast) can be catastrophic.
Don't forget that Hurricane Helene that hit Florida, Georgia, and the Appalachians,
flooded the hillsides and rivers, blew down trees which temporarily dammed up the rivers which later fell apart,
sending a deluge of water into the lowlands.
Massive erosion of the valleys just added to the debris and thus isolated those along the valleys.
This storm potential ain't no joke !

They must have only used the term amongst themselves because I don’t ever recall hearing about it until recently. Growing up during the cold war, I do recall many times the weatherman forecasting how we would be getting cold fronts coming down from communist Siberia, but not bomb cyclones, or atmospheric rivers, or polar vortexes. Now that the cold war is over I guess the nationality of the cold fronts don’t matter so much, but they must be made to seem more ferocious, mean, and angry cold fronts because humans have mistreated mother nature or something.
