SNOW & ICE coverage in the Northern Hemisphere 2016/17

[Gavin Hannah]

 

Whooop!!! 

This probably is aimed more at the model aficionados, but unlike last year, it appears to me at least that we are seeing a lot more in the way of Scandi blocking compared with this time last year..? Hopefully, a good omen for the Winter coming.

More good news for Scandinavia.

In the loo. I've been eating lots of fibre

Steady (but rapid) build of snow and indeed ice in the past week, good to see the snow stretching into Scandinavia too.

Does anyone have a link to the archives of snow and ice coverage? I'd like to go back and investigate and compare the evolution of the recent colder winters to this season so far (2009/2010, 2010/2011, 2012/2013).

Thanks!

good to see the snow in Scandinavia ,i think this is of more importance to us than a good cover in siberia etc think 2009 didnt have extensive eurasia cover but did have good cover in the northern latitudes and Scandinavia.not sure huge eurasian snowcover and subsequent huge high pressure aids us greatly,still learning but arent we all with this one

Icy cold pack-ice clogged seas extending south over the Norwegian Sea and into the NE Atlantic would also help encourage high-pressure to the north of Britain. This would also shift the temperature gradients vital for storm tracks into lower latitudes and this would also be good for the chances of more easterly and northerly winds over Britain: Unfortunately precious little sign of that at present!

Past 14 days of Europe/Asia Ice/Snowfall pretty amazing how some of that is filling in so quickly and watching the ice-cap grow. 

[Turnedoutniceagain]

Snow pushing further south into Mongolia now. Canada's filling up well

[Frozen Britain]

Is there a link between AO and Eurasian snow cover during Autumn? What I mean is, if the AO is negative how does that impact on snowcover? Does it help or hinder it? What about AO? Is there any correlation or link between them, or is there no concluding evidence? I know Steve Murr has already looked at Octobers with a -AO and what that means for the winter months, but what about the impact of that on snowcover?

Rapid snow gain south of 60N in October is correlated with a -AO in winter.

The Norwegian Sea has no ice cover throughout the year and probably hasn't for the past 8000 years.

I think Ian knows that to be fair. Remember, he is the sort of chap who (quite brilliantly) thinks of extreme scenarios, like slowing or reversing the rotation of the earth. It is all a bit of fun.

Well he's implying that it's the only way we'll get HP to the N of Britain which is patently false, as indeed the past week has shown.

I'm not so sure.

I have some WW2 books and they have some Admiralty sea charts from the war in there, and they show maximum Winter sea ice extending into the Norwegian Sea.

But on the the other hand nature is quite capable of making things go  boobies up. 

[Ice Day]

Just out of interest and for a bit of fun, I thought I would compare how today's Snow and Ice coverage compares to the equivalent day in 2010 (which was around 5 weeks before the snow kicked in).

Interestingly there is quite a difference, 2010 had far more sea ice than this year, but far less snow over Eurasia and Canada than we're seeing now .  The snow line this year is also much further south with the 60N line being breached already in several locations and approaching 45N in Mongolia.  Can't profess to know if this is going to pan out in favour of those looking for cold, but it certainly seems positive at the moment.

It may mean winter will kick in a couple of weeks earlier this year

Of course it does, I should have made the connection.  Right, I'm taking the 15th November off work to enjoy the blizzard!

I booked off the 7th so probably a week too early ha ha.

Yeah, well I'll probably have to take a couple of days off work mid Nov as there 2 'in service days' at our youngest's school. Just don't make the blizzard then as it's a waste of a potential extra day off work

No he isn't, he is clearly being tongue in cheek and indulging his rather interesting take on extreme scenarios. He said "Icy cold pack-ice clogged seas extending south over the Norwegian Sea and into the NE Atlantic would also help encourage high-pressure to the north of Britain" (my emphasis). Hardly what you're suggesting. Give the man a break and stop taking yourself so seriously. Sometimes it is ok to have fun

Here is the latest snow and ice chart for Thursday.
