    Thanks, Midlands Ice Age. Will check that later.

     

    Right can anybody tell me what level of snow NOAA maps report.

    Climatereanalyser has shown snow in Mexico and southern Texas,  and Mississippi and Alabama for 3 days. It's not melted which is very unusual for this time of year but it has been exceptionally cold. It's also shown Nebraska and Tennessee completely covered for 3 days. However, NOAA has shown no snow in these areas. I've noticed slight differences before but not the huge difference we have this time.

    There is definitely snow there so why does NOAA not pick it up? What's the point of posting NOAA images all the time to show where it has snowed if they are missing significant snow? There has been snow into the Deep South and Mexico but NOAA does not show it. They indicate about 20-25% US coverage while Climatereanalyser shows maybe 40%+. This is not a small difference!

    Net positive snow cover anomaly in the NH at the moment. Expect the reds in N and E Europe to grow in the next 7 - 10 days though, sadly, as warmer air moves north into this part of the world.

    Hopefully the Kara will finish freezing before this happens...seems to be icing over mighty quick right now.

    Interesting spell of weather coming up, with some signals for the PV to migrate over to the E. Siberian side of the pole in a week or so. Still seems quite a fluid situation so will be hard to predict where we'll be, in terms of a hemispheric pattern, as we approach December and winter proper...

    Thanks guys for your contributions above...

    Aleman  -   certainly does seem odd that it is not picking up maybe an inch of snow?

    We will be seeing shortly in the UK (I hope), what it takes to pick that level up.  

    US nic  today shown several times already above.. 

    Snow has expanded southwards in Central Southern Asia, so maybe cancelling out the 'red' anomalies there, elsewhere no real change shown. 

    Kara is rapidly filling in the middle bit now..  Is it a race against the warmer weather?

    Elsewhere gains again for Chukchi and Beaufort.  Baffin also continuing with its 'catchup'. 

    Hudson,and Greenland continue to ice quite nicely now.     CAA is just filling up -   slowly.

    Possible small losses in Barents and the ESS today.

    My guess Is for an increase of about 70K Km2 - still above the now 50K Km2 average for the day.

    Back later ...

    Ed..

     You are correct - to a certain extent. It does not explain why the whole of the northern hemisphere is seeing increased snowfall.

    How far do you think that the moisture associated with 'Arctic Amplification' goes?

    I have a map of the snowfall on Greenland which might give a clue.

    Figure-3b_snowfall.png

    It seems to be about 10-50 miles only.

    Also , Interestingly Greenland does show a net snowfall gain over the last 12months, but only around the coasts, and this will  also not be picked up on the Rutgers map..

    It must be realised that the Arctic is one of the driest places on earth. (along with Antarctica, and the deserts). So any increased Arctic moisture  cannot account for increased snowfall 1000 to 3000 miles away.

    image.thumb.png.75254130b205cc37d9b6e292e240e2fe.png

     

    Isn't it more suggestive of the temperatures where it is snowing in the lower latitudes.?

    PS   I know about the Surface Mass Balance of Greenland, but that takes us off topic......

    Well, three factors (which pass the obligatory test of being consistent with the observed fact of global warming) spring to mind: the aforementioned Arctic Amplification, quasi-random synoptic fluctuation, and the current Solar minimum...There will, most likely, be several others, however...?

    And, anything mooted, that's not consistent with reality, should be jettisoned at the earliest opportunity...:oldgood:

    Thanks for the above Liltbrockie(?)

    How did you count the pixels?

     

    As for  the 'tipoff' from KW..

    At least it is now being looked at and researched. Is it coincidence that the hole and the open ocean are coincident(!) ….

    However  - they have not yet picked up that 'atop' of all that is the very high levels of ozone.

    I will check the current Ozone levels out again later.

     

    I now come back to my reporting on the Masie figures.

     

    Once again I under estimated the growth!!!  I must give up guessing.

    Yet another century increase of +117K Km2. Double the seasonal average value.

    As applicable to the discussion above - guess where the large increases are?   

     

    Yep...you guessed it. No less than Beaufort(+54K) and Chukchi(+23K).              That is well over halve the rise recorded.

    What did I say about the sst's having a chance to cool  down?  I really do think that the stratospheric anomaly in ozone is having some effect on the  surface readings coming from the area.

    It does seem to me that the alleged slow down in the ice refreeze may be incorrectly based. Closer examination of Masie in Chukchi shows large amounts of scattered ice. This is a signal for a quicker refreeze coming up - not slower.

     

    Elsewhere, large gains in Kara(+22K), Baffin(+11K) and Hudson(+19K)   - all expected.

    Small losses in Bering(-3K, I thought the loss would be classed as ESS), and a larger loss in Barents(-9K) - again expected.

    This latter may be more significant as the ice front was pushed slightly north around Svalbard.

    I realise that this isn't particularly interesting as lowland England has also seen snow this week, but Valence, at just 100m in the Rhone valley and known as where the south of France starts, has seen an unusual November snowfall.

    This is developing incredibly so far with the unusual Synoptics around too, cold records getting well broken from US to Scandinavia, unexpected early snowfall in lowland locations, the very rapid snow expanse last week of Oct.  The refreeze has been nothing less than startling.....very least sit up and look!  For me it’s linked to the solar cycle and the deep minima we continue to enter (and not just this Schwabe minima of cycle 24 we are in) but the projected and anticipated deepening  Grand Minima we have entered.  Keep up the reports guys.....fascinating watch this

    The data itself shows that Oct 2019 was in 5th position out of 52 in the rankings of the years.

    To be fair that's quite impressive. Top 5 from 52 perhaps suggests more than an eye brow raising moment. Which years sit in the top 4? Any others from the "modern" era?

    Morning all...

    Just noticed a big increase in snow over the French Alps  and Spain this morning.. Also that the snow line has now reached the Pacific. So the whole mass has moved Eastward.

     

    US nic this morning - thanks to Katrine for posting the graphic....

    A general increase in ice cover with only Barents looking to lose out, Southern Kara is rapidly filling in, but Northern Kara was reduced somewhat by the movement of the polar ice cap slightly north.

    Large increases in both Beaufort(if not already full!) and Chukchi again, despite the warm temperatures shown there.

    This morning we have some information from the Mosaic project...

    It seems that they were buffeted a storm for 3 -4 days from around the 10th of November and hence communication was negligible.

    A very latest  report has shown that the temperature in the area has increased to round -14C this week. So an increase of around 7 -10  degrees has occurred.

    Back later with more data.

    Absolutely agree Blast. What people need to understand is that cycles 21 and 22 where 2 of the most active probably since the medieval warm period and cycle 23 started the process we are in. It is no coincidence that the ozone hole and the whole issue of warming from the late 60's occurred during cycle 21/22. I believe we are in for a period of Dalton winters over the coming 5 years. I also believe the rainfall etc is due to the cloud seeding effect of cosmic rays which could therefore increase  snowfall in winter. The 15/20 years are going to change how we understand the influencers on climatic patterns and actually realise the strength of the solar cycles is what determines the deviation from what may be classed as normal

    Totally and wholeheartedly agree with this. What has happened this year in the southern hemisphere winter and Spring, with Australia and New Zealand having there snowiest springs for over 40yrs, and parts of South American, especially Chile also having colder than average springs. It's now the Northern hemisphere experiencing cold and snowy starts to Autumn/Winter. It certainly should start raising some eyebrows, with regards to which way temperatures are heading over the coming years! 

    Interesting times indeed.
