Snow and Ice in the Northern Hemisphere 2013/14

[Yarmy]

Thank you for keeping the thread on topic.I notice a big jump in snow cover from 27th to 29th. Would you say this is well above average?

It's well below the average for the 2000s even and a long way below the longer term average. However, there's a school of thought that it can make conditions more conducive for colder, snowier winters in Northern Europe.

Yes this post further up had the anomaly to a few days ago and I suspect its become bigger since the end of that graph a few days ago.

It's well below the average for the 2000s even and a long way below the longer term average. However, there's a school of thought that it can make conditions more conducive for colder, snowier winters in Northern Europe.

 

I think that's the ice you are referring to I think the snowcover is well above average.

Oops yes. Ice is still way down, but that is possibly a good thing in terms of winter prospects (although perhaps not so good generally!). Snowcover is well up, and let's hope it continues through October and November.

Please take a look to 30 september 2013 vs 30 september 2012. A world of difference.

 

In the next days the easterly parts of Siberia will get snow.

Ice extent us the highest its been for a number of years at this point in the season.

Snow cover is well above average.

SSTs are 4 degrees above avg in the north west atlantic so im not sure how that will affect things for ice formation and weather patterns in the winter. Good for convection i guess.

Long term average, ice is way below par. The links i post demonstrate this in a neat chart.

Snow now spreading into European part of Russia.

Brasov,Romania earlier on today. First snow of the season!

Snow in Longyearben this morning, the mountains on the far side are obscured by mist but the snowline from yesterday has definitely progressed downwards it would appear -

Well there "should" be snow there by now, temperatures there have been markedly above average for a long time, probably related to Arctic ice retreat on the Atlantic side - http://www.yr.no/place/Norway/Svalbard/Longyearbyen/statistics.html

The past 14 months have all been warmer than average with the mean monthly temperature of -2.1°C being 3.2 degrees above the normal -5.3°C over this period.

Well maybe its all about the gains this month not what should and shouldn't be there.

Maybe Longyearbyen's snow has actually no bearing on our weather whatsoever!

 

edit: Expanding the point a little, clearly if people are looking ahead for trends then what should/shouldn't be there is a crude definition of anomaly so is important.

Check out the climb the red line is making.  Looking very steep. 

[cheeky_monkey]

Snow flurries in the forecast for Calgary overnight and into tomorrow morning.

HI , the values you posted on the 26th below , since then and todays value growth is approximately half a million square km.

is this normal for such rapid expansion for the time of year up there? 

 

The latest value: 5,183,869 km²â€‚(September 26, 2013)

Some big gain in both snow and ice, today vs. yesterday

[smithyweather]

Wow thats a pretty big gain.

So much for this theory of no big gains due to large snow cover.

Edited October 2, 2013 by smithyweather

[Mark Neal.]

Rather big gain. If we can keep seeing similar gains, it certainly bodes well

[LincolnSnowstorm]

Positive gains http://www.youtube.com/watch?v=-MrxA1KXWJk but also a growing amount of red negative anomaly in places  blue or red which will win this October?!

Moldova has had snowfalls, this is a month earlier, .Normally they have their first snowfalls at the end of this month which melt quickly. But seeming the snow has stayed around this time

Its very normal (average increase around 100k a day this time of year long term trend)

 

Two 98k increases in a row.on the IJIS

 

you can see all the figures on here

 

http://www.ijis.iarc.uaf.edu/seaice/extent/plot_v2.csv,

 

were 2m below the 1980s figures, however relative to recent years we are seeing a good trend upwards.

 

still 1.759 mil on up on last yr record low and heading quickly to the 2000s average
