Still I suppose it is not so surprising considering the stationary
cold trough of recent weeks. Be interesting to see the effect on our
summer. And the eventual minimum come September. Any predictions?
Lower, higher or the same as 2012?
The excess over 2012 is in the Atlantic side of the Arctic. on the other
side of the Arctic, conditions are lighter than that year and the 2nd
lightest year, 2016. I'm wondering whether more ice has been forced out
of the Arctic which may lead to a new record low. We'll just have to
wait and see.
When I was producing ice charts fifty years ago, I never saw any
relationship between Arctic ice conditions and our weather apart from
the heavy ice conditions off E Greenland in the sixties making any
northerlies colder than they'd normally be. The pressure distribution
was more attuned to SST anomalies in the western N Atlantic.
The natural state for the typical British weather is cold Lows in Greenland.. Exceptions to the rule are Anticyclones like the one produced coincidentally by the eruption of Popocataptle. Not that extra-cool weather from anticyclones has been the cause of this:
"Jakobshavn Glacier in western Greenland, best known for being world's fastest-moving glacier, is growing for the third year in a row. By the third year, thickening is occurring across an increasingly wide area.
The glacier has spent decades in retreat until scientists observed an unexpected advance between 2016 and 2017. In addition to growing toward the ocean, the glacier was found to be slowing and thickening."
Deeply upsetting for the Dawlish among the flowerpots on here. Too bad.
