The surface level equivalent to the Jet Stream. …
I was looking at the northern hemisphere chart here: http://www.opc.ncep.noaa.gov/ and clicking on the links in it.It gives you close ups of three major regions, the Atlantic, The Pacific and North America.
Then I noticed that the major weather front in North America extends from what I thought must be Cape Hatteras through towards the Aleutians.
And the bell went off.
When a storm leaves Capoe Hatteras there is an upsurge in the activity of whatever part or parts of the Aleutians is some 80 degrees from the east coastal point or points involved.
That is as far as I ever got in the few years I have known about it.
Some time after I discovered that first connection I realised that there were front that seemed to extend through the Met Office's North Atlantic chart towards Chile or whatever part of South America the storms involved in the North Atlantic were going to have/produce/result in quakes following them.
Of course there is a limit to how far the North Atlantic fronts went and since I was stymied in getting more charts and or details, I just left it at that.
Obviously I began to realise that the fronts if long and large and especially of suitable duration (about 3 days) then the little that was showing of them was enough to indicated South Americans aught to get under their tables.
So when just now I realised that the US charts were showing me the fronts in their entirety, running from in this case South Aulatsivik Island, Labrador. (Yes, no storm there just a front. I know, I know, damnit, I saw it first fool!)
It joins up to a cold front almost immediately then it becomes a sequence of one or the other all the way through to some god-forsaken wilderness on the coast of the Brook Range/Beaufort sea. (Is that how the great man is remembered a briny sump off Godknowswhereland, Alaska?)
Just to the west, off Ireallycantbebotheredlookingland there is another frontal system. It reaches to (I believe) Northern Spain.
So now what do I do?
Here are the charts I have been looking at. They are not very clear. I can see me having to move to Exitdoor in the hope that the MetO library will have better.
(At least I should take a few days to go there and look.)
If I were more careful I'd copy and paste the URL from the slides but hell…
What do you want me to do smoke it for you?
