FUBAR - the state of the arctic ice pack in recent years. ;)
...Ivica, what is ZIS ?? Never read about this...
Stumbled upon this list: http://www.nodc.noaa.gov/General/mhdj_acronyms3.html (http://www.nodc.noaa.gov/General/mhdj_acronyms3.html)I'll give them props for these two:
Thought it might be a help. :)
Anyone know minimum size of polynya to be excluded from SIE number?It doesn't work like that.
Neven,
I just wanted to the time zone displayed in this forum.
a low resolution labeled picture showing which areas of the arctic are refereed to by each of the area graphs would be nice
as eg : https://en.wikipedia.org/wiki/Barents_Sea (https://en.wikipedia.org/wiki/Barents_Sea) doesn't list actually what area is talked about, but we're quite happy to list the amount of ice in it at https://sites.google.com/site/arcticseaicegraphs/regional (https://sites.google.com/site/arcticseaicegraphs/regional)
perhaps something like a labeled version of the following?
(https://forum.arctic-sea-ice.net/proxy.php?request=http%3A%2F%2Farctic.atmos.uiuc.edu%2Fcryosphere%2FIMAGES%2Fregion.mask.gif&hash=27d29e652d91a46d975576c2bea1fd6b)
I've been wanting/planning to do this for ages, but somehow never did. I'll make a labelled map and add it to the Regional Graphs page. Thanks for reminding me, Andy.
And add to that the acronyms that had me baffled in the beginning:
ESS = East Siberian Sea
CAA = Canadaian Archipelago
CAB = Central Arctic basin

Weather forecasting modelsThanks. Tropical Tidbits,
GFS - Global Forecast System
ECMWF (AKA Euro) - European Centre for Medium-Range Weather Forecasts
UKMO - United Kingdom Meteorological Office
NAVGEM - Navy Global Environmental Model
See the sidebar at MeteoCiel (http://meteociel.fr/) for a few more!
Their ensembles of the models are not obvious to me from their acronyms:
EPS
GEFS
GEPS
Anyone?

Neven,
I do not know which thread would be appropriate for this question.
"FJI" is repeatedly used by at least 3 posters (for example: today's "Just a followup from yesterday on the poleward region poleward of Barents-FJl." by A-Team). Pmt111500 suggested it means Franz Josef Islands when I asked. There is some support for this when I do an internet search (~5 results for "FJI" "Franz Josef Islands" plus "FJI" "Franz Joseph Islands"). Should FJI be added to the glossary? Or should folks be asked to use the standard "FJL" [Franz Josef(ph) Land](~13,000 internet search hits)?
NWP North West Passage
Is it an idea to add the difference between Extent and Area in the list?
If I understand correctly Extent is based on a grid where every tile in that grid that has 15% or more ice cover is counted and Area only the ice cover is counted?

[2017-03-10] 1000+ terms added to the cryosphere glossary!. We"ve just added over 1000 entries to the cryosphere glossary! There are now 4141 entries from 26 sources; over 2200 are unique. http://globalcryospherewatch.org/reference/glossary.php. (http://globalcryospherewatch.org/reference/glossary.php.)
Hi can can anyone define "torching", from what i can tell its when ice changes albedo and starts looking darker on filtered satellite images? What are the implications of this for the melt?I will try though I'm no expert:
Should "SSTA" be in the page 1 glossary? SSTA = Sea Surface Temperature Anomalies in the 2017 ENSO thread. It was just used (undefined) in the 2017 Melting Season thread.
For more terms you can refer to NSIDC's Glossary. Or peruse the Global Croysphere ???::)
I think the opening of the CAA may be more important than it initially appears to be. It's kind of like opening a pressure relief valve of sorts. It seems to me, with my limited experience, to change the dynamics within the CAB.
pauldry600QuoteThe Canadian Arpegio (or however you spell it) is notoriously difficult to break down so it may not all go but this will surely test it to the limitIt don't have to all go, as in melt. If enough gets weakened and broken up, the rest will eventually just flush out. Remember that at the end of last melt season, smaller floes were moving through until the end and got frozen together. I don't suspect the bonds between these to be any stronger than elsewhere. Also, wave activity has been infiltrating some of the channels, despite the dampening effect of the ice.
Can someone explain ' GARLIC PRESS 'Not the correct place for the question, but "garlic press" of the canadian arctic archipelago is just an euphemism for the structure and currents of it. Sufficiently weak ice north of the archipelago gets broken by the combined effect of dominant currents from north, the assisting winds and the narrow channels in there providing grinding effect. The resulting mush of rather thick pieces of ice gets spread along the center of Northwest passage, and is still a hazard for weaker ships travelling there... Much easirr to say "garlic press" ;-).
...Searching for "Global Mean Surface Temperature Anom" in the relevant thread has four 'hits', so I'm guessing I guessed right.
The second attached image shows Gavin Schmidt's pre-industrial GMSTA projection for the end of 2016 (based on data through the end of September 2016) indicate a mean value of 1.25C by the end of Dec 2016. However, Gavin's projection is based on historical data and thus ESLD in a world with acceleration global warming. This is indicated by the third attached image of daily NCEP/NCAR GMSTA values through Oct 16 2016; indicating that the world continues to be running hot.
SWE - Snow Water EquivalentBut SWE can mean....
Side note: It appears that all you lovely people are now on the brink of developing a totally new & unique language, which is based entirely on acronyms. Extremely interesting from an ethnolinguistics perspective, I must say! (but one helluva bugger to learn! The dev team at Rosetta Stone have their work cut out for them!)
SOI - Southern Oscillation Index ;DOh, was that one missing??? What a bunch of amateurs we are!?!? Just one of the main ENSO components. Well, thank you for the addition.
Actually it was already added back in August, as can be seen directly upthread.SOI - Southern Oscillation Index ;DOh, was that one missing?
Hi OLN,
What is a "saddle collapse"?I think its when you have a glacial mountain-pass (saddle) of ice, which as it melts changes water and ice flow to cause a positive feedback on melting.
Or, the description of when an ice sheet reaches a tipping point as it melts. The Laurentide Ice Sheet experienced a saddle collapse over Hudson Bay as it disintegrated into the Keewatin and Labrador sub sheets.What is a "saddle collapse"?I think its when you have a glacial mountain-pass (saddle) of ice, which as it melts changes water and ice flow to cause a positive feedback on melting.
What is a "saddle collapse"?The term "saddle" comes from geography and refers to the landscape shape of a pass between two hills, i.e. like the saddle on a horse.
Soil Moisture and Ocean Salinity, or SMOS, is a satellite which forms part of ESA's Living Planet Programme. It is intended to provide new insights into Earth's water cycle and climate. In addition, it is intended to provide improved weather forecasting and monitoring of snow and ice accumulation
to add DMI - Danish Meteorloglical Institute, usually referring to their chart of average temperature north of 80N. My understanding is that those temperatures are not area-weighted. So small circle at 89N gets as much weight as much larger area at 80N.
Warm Air Advection (a more scientific sounding term than 'balmy winds' ;) ). Added now.Right. Basically :-) thanks for better explanation
the model run is NOT breaking down the effect from the FSW (earlier post wrt Judah Cohens tweet)
The annual-mean incident solar radiation at the top of the atmosphere (FSW) varies significantly over the Arctic Ocean latitudes ranging from about 210 W m-2 at 65oN (roughly the latitude of Bering Strait) to less than 175 W m-2 at the North Pole.
FSW from here (http://www.atmos.albany.edu/facstaff/brose/classes/ATM623_Spring2015/Notes/Lectures/Lecture11%20--%20Insolation.html)[Edited]
Fsw = Daily average solar radiation in W/m^2.
Just saw this being used but not in your glossary.
AGW - Anthropogenic Global Warming
CIS Added.
EEI: Earth energy imbalance.Added.
Although it is missing the actual technical definition of ice area under 1 million square miles.I thought it was one million square kilometers.
CAS = Central Arctic Sea. Used by NSIDC. Which gerontocrat tells us is 3.2 km2 less than the CAB. JAXA uses CAB right?Whoops - we are talking about the division of the High Arctic into the 7 central seas
