S2K Weather Acronyms

#1 Postby olddude » Mon Jul 02, 2007 1:32 pm

This is an effort for the less weather-savvy of us. In honor of my 100th post I think it is time I try to offer something back to this board.
I have learned a great deal and gleaned valuable information but many times on this board I will come upon an acronym in which I am clueless as to the meaning. Many are on the Jetstream list http://www.srh.weather.gov/jetstream/append/acronyms_a.htm but alas, many are not. I hope this list helps some other folks. If anyone wishes to add to this list I would appreciate it.

I'm going to sticky this for now. Maybe in the future, we can have something that links to these at the top of the page. For now, please feel free to add to the list by replying and I, or another member of the staff, can add it to the list above.

Thanks, Scott.

I think you made an error. You should place "tropospheric" in that section.

No idea why I did that. Brain was broken at the time. Thanks for letting me know :)

Corrected now

Surely you mean became operational, as it is now the 2007-08 South Pacific season ;)


SREF - Short Range Ensemble Forecast
ECMWF - European Center for Medium-Range Weather Forecasting (it's another model, called the Euro or the EC for short)
FSUSE - Florida State University Superensemble
POES - Polar Orbiting Environmental Satellite
KMA - Korean Meteorological Agency
SEC - Space Environment Center, part of NCEP
AWC - Aviation Weather Center, part of NCEP

In relation to the BAM models, you'll always see them as one of the following:
BAMS - BAM Shallow (for weak systems/systems steered by shallow aspects of the atmoshpere)
BAMM - BAM Medium (for medium-depth systems)
BAMD - BAM Deep (fore deep/vertically tall systems)

And a correction - ET is technically extratropical transition, though it is often used just to indicate "extratropical" as well.

Actually, no, it doesn't start until October/November officially, the "TC year" is what starts July 1, according to the op plan.
