2012/2013.. 70hPa…Northern hemisphere polar Stratosphere temperature anomaly
Thanks to REN for his snap

ACCESS G is indicating a severe intense low in the sub-polar Nth pacific next Wednesday the 6th nov 2013. Last year a severe low in the same place accompanied an Sudden Stratospheric Warming event.
So this is a heads up ‘watch alert’

Another intense low forming in the sub-polar nth pacific around the 16th december 2013
Maybe a little early for an SSW . I think the big ones tens to occur in the depthsof NH winter
