Maybe she wasn't bombing, but she was a bomb for the North Gulf Coast.

I think the stardard for bombing is way to high. Like what is going to drop much faster then what Katrina did.

For rapid deepening, the minimum is 42mb over 24 hours--so this makes it, just barely. "Bombing" is not a term that is defined in the NWS glossary :lol:

Millibars is simply the "other" way to read pressure... like meters to inches and liters to gallons.

Well over here it would be used if a system dropped by 24hPa in a 24hour period.

I agree alot more with your system of deeping.

Looking into this a bit closer the term bombing does appear to be relevant here.

The definition of a bomb only mentions extratropical cyclones (Note this is a British book), however looking at the definition for deepening it says it can be a tropical cyclone which falls by 24hPa in 24hours.

In my book...any storm that reaches CAT 5 has bombed out.

The SI units for pressure in Nm^-2, or kgm^-1s^-2 if you take it right back to base units.

1 Millibar is 100 Pascals.

Most of the books I've read state that "explosive cyclogenesis" (or "bombing" is deepening 24mb (or hPa) or more in 24 hours.
