BethesdaWX Posted September 10, 2011 Share Posted September 10, 2011 Funny that you would mention shortly before the HUGE GAINS IN SIBERIA AND ALASKA!!! SNOW PIXEL COUNTS (total white minus 8000 [approximate number of white pixels that are map lines and not snow]) Yesterday: 337 Today: 572 One year ago today: 428 ICE PIXEL COUNTS (total yellow) Yesterday: 1484 Today: 1443 One year ago today: 1634 Pixel counting seems a bit excesive. Ahead of last yr, nice...does it mean anything? Not really? Link to comment Share on other sites More sharing options...

weathafella Posted September 11, 2011 Share Posted September 11, 2011 And exactly why is no one else able to start a thread on snow cover? <img src='http://208.71.34.143/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' /> If you're going to do this thread, at least don't use the exact wording of the thread title I've been using. I normally wait until 9/15 or later to measure because IMHO, it means nothing now. Link to comment Share on other sites More sharing options...
BethesdaWX Posted September 11, 2011 Share Posted September 11, 2011 no that's not what you were saying but w/e Who are you tell me what I was thinking? No, you're blatantly wrong, there is no correlation of the NAO to sea ice, end of story. Yeah exactly SST's were very warm in 2010 yet snowcover was quite high, coinciding with the -NAO and asociated storm track configuration. As for sea ice there isn't any correlation there at all upon looking at it, that'll fluctuate over extended timscales apart from the NAO or Synoptical patterns.

skierinvermont Posted September 13, 2011 Share Posted September 13, 2011 How accurate is the pixel counting and is it even something worthy of following? i'm sure it's perfectly accurate he's using a program to count em. the only problem is because of the shape of the earth and the fact that it is being presented in 2D some pixels probably represent somewhat more area than others. But in terms of accurately comparing year to year pixel counts.. I'd guess the # of pixels is proportional to area within 1%. The only way it wouldn't be is if one year had a much higher proportion of total snow located in the mid or lower latitudes than another year (Himalayas for example).

I'd do it, but I really don't feel like staying at work until it gets created. Link to comment Share on other sites More sharing options...
okie333 Posted September 13, 2011 Share Posted September 13, 2011 FSU says back up to normal as of 9/11... keep in mind that this includes both snow and ice, so in this low ice minimum a normal number is phenomenally good. Link to comment Share on other sites More sharing options...
winterymix Posted September 14, 2011 Share Posted September 14, 2011 Are people really discussing snow and ice cover of a warm world, summer on the wan? It seem normalish for a warm world. We've still got tropical activity to get through in the NH. Daylight is still longer than night. Link to comment Share on other sites More sharing options...

The snow in Siberia is way above average right now, but I don't think this means anything this early. We can see it change very quickly as it did in both 2009 and 2010.

I thought it was stated on this board a while back that above normal snow cover in Eurasia(?) was a signal of a colder than normal, snowier than normal for us in the northern hemisphere??

In October it is, you want to average the month of October above normal and it then correlates fairly well to a -AO/NAO. The snow cover anomalies can swing very wildly in the first few weeks of September because climo covers a small area where snow should be. Once we get into latter September, then it becomes a little more interesting, but even in years like 2009, October started off poorly WRT snow cover and then spiked way above average about halfway through the month and finished quite positive.

Okay, then why not wait till oct to start talking about snow cover, when it means something, instead of sept when there is no correlation??

That's what I would do, but some people like to track it earlier. If you build up a monster positive anomaly toward the latter half of this month, then it certainly would be favorable for October I would think...starting off high.

skierinvermont Posted September 14, 2011 Share Posted September 14, 2011 yup given how little snow there is in September, it's probably completely meaningless until sept 20 or 25.. things can change very rapidly in just a few days because by October climo is to gain snow cover rapidly.

SnowGoose69 Posted September 14, 2011 Share Posted September 14, 2011 There are huge swings sometimes as early as the start of November. Last year I think we made huge gains in either late September or October (I want to say it was October) and then we had a massive cliff fall off at the start of November before it rapidly recovered.

violinist Posted September 14, 2011 Share Posted September 14, 2011 Now you're getting it. Nah, I really am just reading and learning at this point. I dont read all the forecasts that come out here. Just too many . i wait and see what happens. Too many factors determine what's going to really affect the weather. I,m patient enough to just watch and see what develops.
