Interesting article from the New Scientist News:

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.
