Is it over?

The pressures are still in the region of yawn in lower latitudes
despite any ruptures in the Azores high APNf2006, so what is going on?

The spell ushered in by the phase on the 7th of October (at 03:13) is a
classical thunderstorm spell.

And we have had classical thundery weather. One thunderstorm does not
an Autumn make, of course. But if -as seems likely to happen, the misty
weather forecast today (Thor'sday) brings with it an hurricane in the
southern reaches of the North Atlantic, I think we can safely say that
the strange weather has returned to what we had come to believe was
normal.

Suppose it was not always thus.

And more important: What caused it and will it last?

Ruptures. That is what the "deep low" breaking through the indolent air
masses in the midle latitudes of the N Atlantic looks like.

Over the east coast of Canada a low of 1007 points to the fact that
whoever is filling in the data lines on a map, is following an arbitary
code of conduct more than linking meteorological coincidentae. In the
west Atlantic the high of 1028 belies it.

Then there is the "deep" low in the Middle of the N Atlantic. At its
deepest it is 991 mb. That is on the low side but not by much. It's
about 10 millibars off the midway point on most barometer legends. It's
to the rainy side of "Change."

There is a high of 1037 ver Scandinavia. That is high. 31 and a half
inches of mercury puts it on the borders of "Very Dry" as the legend
would have it.

What is up I wonder? Is it something of biblical proportions, something
akin to the plague of gnats, or what?

The northern hemisphere was wrapped in a blanket of snow earlier this
year. Wasn't that about the date these indolent air masses began to
appear? April wasn't it? A plague of snow with only god's own people
preserved from it. For their awareness?

Hardly. There is nothing godly about the British and the Irish. The Low
would have to go down to 960 or '70 to give us back our normal
interesting weather. (About 28 1/2" of mercury wouyld put it at the
other end of the spectrum to the Scandinavian High.)

The weather might seem, boring though it is giving rise to some foggy
weather. We might even get a pea souper out of it if the trend holds.
TV reception is pretty bad. (But since TV programmes are even worse,
not many real people will complain.) And next weeks spell is a
classically misty one.

I would have thought the phenomenon interesting enough to provoke
discussion. I wasn't hoping to be involved. I admit to being a little
strong for most stomachs. But the indolence is mirrored, it would seem,
among the few weather fanatics online.

Still never mind, eh?

Musn't grumble.

Talking of swarms...
One thinks one has solved all the riddles* about so anomalous positive
and negative activity in NAO (ergo the elnino SOs and any amount of
others) and here is a taster:

"I was just looking for swarms for Coso Junction but of course there
were none, as there were no super cyclones active at that time:
http://www.metoffice.com/sec2/sec2cy...2001/july.html

However there was a swarm for the supertyphoon Durian:

1.1 Tropical cyclones ending during the month

Storm Name: DURIAN
Basin: NWP (North West Pacific)
Start date: 29.06.2001
End date: 07.07.2001
Maximum sustained wind: 75 knots

Which put it in line for the swarm reported near Seattle by Damon Hill
on Saturday the 7th of July 2001:
http://groups.google.com/group/sci.g...se_frm/month/2...
"

http://groups.google.com/group/sci.g...d108b235701ba5

*Or not as the case may be.
It would be a simple exercise to locate a supercyclone in one of the
above links and reports of swarms in one of the others.

You'd think I'd bother to do so then, wouldn't you?
