We would like a little of that cold. It reached 43 degC in Melbourne yesterday. Now 17 degC after two cool changes!! I would be happy to share it with you if I could!

It was a tad cool. The reflections are called sun dogs. Very cold ice crystals reflecting of the sunlight. I took this just up the road a bit. Attachments:

If that ends up heading to Greenland, it could really stir things up, all that tropical moisture hitting the arctic air mass

Still fairly cold in Helsinki and after a few really weak Baltic 'sea ice winters', and a very warm november and december, there is now a good chance this years ice will be fairly reasonable because once we get past the first few days of February we will have solid minus degrees till March. en.ilmatieteenlaitos.fi/ice-conditionsen.ilmatieteenlaitos.fi/local-weatherAnd still no snow plows on our road and since we have been gritted we are probably safe till snow arrives next week.

You are a hardy bunch thar in the Midlands! So, you will just shake your head and wonder what all the fuss is about......-3C you say? Heck, imagine if it was -30C. Then you may notice a breeze. yeah i agree with you on some lvl sig but the cold here is not like canada or the usa .. it's has a heavy damp to it .. have walked around banff and calgary in -20 with just a jumper and jean jacket on .. could not do that here go's thru to the bone .. but then again age might have somthing to do with it .. I can remember being in Labrador outside air was -37C but it didn't feel cold as there was close to no humidity. Got back to UK and was out in heavy sleet at around 0C and that felt painfully cold. It's like comparing heat in a Louisiana bayou with heat in Death Valley. Humidity makes all the difference - it's called enthalpy

www.nytimes.com/aponline/2016/01/17/world/europe/ap-eu-eastern-europe-snow.htmlDo we have an Eastern Europe winter timeseries? When was the last year this happened? Looks like 2005-06? Going down from SC23 peak Followed by 2008-09 - Cold in Germany-France-Italy (min. between SC23-24) Then 2009-10 - UK coldest in 30 years That north-south jet stream split along eastern UK is looking precarious. An anthology of cold winters from Wiki en.wikipedia.org/wiki/Cold_waveTrivia exercise: The last time there was a monster El Nino followed by a PDO going negative was 1940-41 followed by the monster East European winter of 1941-42 (coldest of 20th Century) when the Wehrmacht froze on the approach to Moscow. On the declining flank of SC 17. Of course I'm stretching ... The winter of 1900-01 was also apparently a very cold one in E. Europe and Russia with snow falling in southern France and Italy. This was the last time the geomagnetic AP index was as low as the current SC24. No truely negative PDO in those years but several large El Ninos and the AMO was apparently about where it is today. In terms of the ~60 cycle, this one is properly placed.

In terms of the ~60 cycle, this one is properly placed. Not sure what you are looking for but there is a very good record of Baltic sea ice going back to 1720. This year is not going to be a bad baltic sea ice winter as the winter only arrived in january and it has not been so very cold. I think it was 2010-11 that was a monster sea ice winter which was comparable in harshness to about 1986 - although 1986 had a bigger extent. The worst sea ice winters of the last century were from about 1963 to 1986 - something like that. last year was a bit of a non event. This year will at least be an average ice winter. The normal period used is however mysteriously the worst ice winter years of the last last century, while the weather normal years in Finland are the last 30 years. :-)) So a so called average ice winter this year will be a worse than average ice winter compared to all of last century.

This looks like it tracks pretty well with the AMO. If the raw figures were available, it would be interesting to plot them together. A new index??
