Mystery blob in the Pacific messes up US weather and ecosystems.

Has there been a related block for the North Atlantic. I monitor the
met model outputs for depression systems coming across the Atlantic ,
for potential marine flooding issues on the south coast of England.
But since last autumn , I'm guessing, 80 or 90 percent of the time
there has been the Azores high extended up in our direction.
Virtually all potential problem storms went well to the north,
Scotlant to Iceland sort of tracks. So no storms to affect the
English Channel this last winter, just a few North Sea issues that
don't realy pass through the Dover Straits to cause any major
problems of surges along the south coast

The effect of the "mystery" blob, or something similar, was documented
some fifty-plus years ago by J Namias. A similar feature of the N
Atlantic was identified around that time by HH Lamb et al. I used my
recollection of the latter's work to correctly predict the dominant
pressure patterns affecting UK over the winter - a rare event for me
but the SST anomaly in the Grand Banks area was particularly strong.

In which case the estuaries of the Pacific coast of North America should be getting red tides this summer. Once you get a whiff of that you never forget it. I imagine the smell of gangrene would be identical.

The Mauna Kea Observatory weather forecasts are the ones to watch. Choose the larger charts as the smaller versions clip Philippines. It provides remarkable warnings of tropical storms.

With the absence of blocking highs in the Gulf they have had a superabundance of rainwater whilst the rivers draining through, California especially, will be choked with algae.

The write up in the OP's link was rather silly though:

"Other marine species showed up thousands of kilometres north of their normal ranges, including pygmy killer whales and tropical species of copepods - tiny crustaceans that are key to marine food webs.

"I've never seen some of these species here before," says plankton expert Bill Peterson of the Northwest Fisheries Science Center in Seattle, Washington - part of the National Oceanic and Atmospheric Administration."

Then:
"But the biggest impacts so far have concerned marine species. Peterson fears that a big drop in copepod populations in waters off the Pacific Northwest could doom harvests of various species of salmon".

I'm trying to remember a fisherman's adage about warm weather covering fishes mouths. An ancient reference to that so called multi-decade oscillation. There was a long standing bout of fall-out from dust storms or volcanic activity earlier this year. I heard versions of speculations about where it came from that I would rather not believe.

Whatever the source, the dust would be feeding plankton and suffocating everything else. I have no idea what ways dust tracks north in that part of the world. I do know the lack of earthquakes equates to a lack of anticyclones (in the very short while I have been watching the region.)

I imagine a self sustaining fertile system would have spells of Lows followed by concomitant Highs. I've never read that anywhere but it seems bloody obvious. I wonder what the fields of France smelled like after some of the world's most luxurious battles.
