[Sea Surface Temperature - SSTs]

CH posted this image a couple of weeks ago either in this thread or the stratosphere thread.

Since then it appears to have grown more intense. This must surely be related to volcanic

activity on the sea bed.

[Stratosphere Temperature Watch]

Very interesting GP, encouraging signs of something far more wintry than what we have

seen so far this decade.

Although as always other indices have to play ball.

[Winter / Autumn 2009-10 Part 4]

Much more in the way of northern blocking around this coming winter compared to last and for us at least, a colder maybe much colder winter is on the cards compared to last.

Thats my punt anyway.

[Stratosphere Temperature Watch]

Ozone levels continue to grow over the northern hemisphere especially over northern Canada and Greenland.

Am I right in thinking this would help promote blocking in these areas?.

[Stratosphere Temperature Watch]

Might this not help with the propagation of the warming down to lower tropospheric levels I wonder.

Hope this helps.

[My Winter Forecast 2009-10]

The thing is the atmosphere is in a more nina like state than nino with a low atmospheric angular momentum. It seems as if we need a kick from the nino to change the pattern and then see how things develope.

Also a strat warming at the 30mb level may well propagate downwards and this could also set the stage for a pattern change in another 10 to 15 days.
