thank god at last, I was beginning to get very confused and starting to make things up just to sound good when my OH, asks me what so and so means.

quick thinking I thought on my behalf :lol:

GFS- Global forecasting sytem my god I got it right :lol: can't be that stupid then :lol:

Many thanks

Glad it's not just me. Sometimes I actually know what it stands for but my brain insist on using the "wrong" wording when I read the intial.

What about FI? I cannot search the forum because of the tem length limit. I know what it means (I think) but not what it stands for?

[IanS]

Good to see that others find this thread useful too. Couple more to add to the collection. Taken from another thread where I was wondering what some abbreviations meant....

From Steve M:

PVA stands for positive vorticity advection- when occuring from the subtropical side of the jet stream will potentially allow deeper cyclogenesis across a region because of the raised thermal gradient-

PFJ Polar front jet stream- The jet stream that is the marked boundry between the cold dry air masses from the North and the mild moist ones from the south-

PPN on the northern side is normally in the form of convectice showers where as on the southern side you are more likly to have rain belts from layered clouds....

AO - Arctic Oscillation - We need a definition for this, any offers?

I would also like to suggest that the first entry on this thread is maintained as a repository for abbreviations. While we do now have this thread, I still urge the more knowledgeable members to use abbreviations rarely in their posts or to at least give the full term once in the text. It will just make post more usable for the majority. OK whinge over.

EVo-

FI refers to ' Fantasy Island-' The often referred to part of the charts between the hours of T180- T384- always over the rainbow...... and far far away-

This is very helpful Steve I feel as though things are starting to make sense..... but a long long way to go me thinks

Ahhhh, excellent, thank you!

(By the way I though it meant Far Intervals, so I'm glad I didn't say what I thought it meant.... Oh dang it I just did )

I guess this all needs to be collated as suggested by scandhi and put in the Net Weather Guides (not wishing to lecture Granny about the eggs!)

[johnholmes]

all in the process, but there are so many things going on it may take a time to show up as such.

Another one I had been wondering about:

GIN SEA= Greenland Iceland Corridor where cyclonic genesis occurs. With Atlantic highs keeping the sytems tracking west to east roughly to the north of the UK bringing mild wet stormy weather to the UK.

[kold weather]

and heres one for summer:

MCS-Meso convective system,a bunch of thunderstorms uniform and become one large system that is able to keep itslef going as new cells keep forming in the system,and so it can go on for a very long time,sometimes for a few days.

RPM Returning Polar Maritime: basically a polar maritime air mass that is modified by a long sea journey from the north west that and travels around the w armer sea as a south westerly behind a cols front: unstable showery and on the whole fairly mild

[johnholmes]

tks ACB, have a look at Air Masses in the Net Wxx Guides.

ps

welocme to Net Wx.

[Snow_Fan_Man]

Cool list, now i know what a ridge is (i thought it was an 'arm' of pressure extending out of the origional pressure system, d'oh!)

What is an outlier?

[johnholmes]

over to the GFS experts, Steve or ?

[kold weather]

Here is just about every term you'll every come across and a breif description as well:

[WBSH]

...but Steve Murr forgot the most important abbreviation of them all. The one that life would have no meaning without!

...

WBSH - Winter Blizzard Summer Heat

B)

[lukenmudge]

When talking about cloubs, what does CB & others stand for?

LM

[johnholmes]

hi L

I'll try and start

the are 'low' clouds=generally their bases are from the surface up to about 6000ft.

Cb=Cumulonimbus=the shower or thunderstorm cloud

Cu=cumulus

Sc=Stratocumulus

St=Stratus

These are called 'medium' level clouds, and generally have bases from about 8,000ft up to around 16-18000ft

As=Altostratus

Ac=Altocumulus

The 'high' clouds from 18000ft up are

Ci=Cirrus

Cc=Cirrocumulus

Cs=Cirrostratus

its much more complex but that will do for starters.

hope it helps

regards

John

[lukenmudge]

Thanks very much John , now i can really follow the boards without getting lost B)

What is CET?

[Adi F]

The Central England Temperature (CET) is a series of average temperatures representative of a triangular central area of the United Kingdom enclosed by Bristol, Manchester and London. The monthly series began in 1659 and daily figures were added from 1772 to date. The CET is the longest available instrumental record of temperature in the world. The CET series was originally constructed by the late Professor Gordon Manley in 1973, and is now routinely updated by the Hadley Centre. Since 1974 the data have been adjusted by 1-2 tenths degC to allow for urban warming.
