What exactly is a blocking Low?


Well I am blowed! I finally got the images to load correctly on this website.


This is the normal course of events these days with the North Atlantic.


A large cyclon appears in the middle of the Mid Atlantic ridge and has a heart of warnm fronts coiled inside it.


It had appeared initially TAIAP from Newfoundland, just like its replacement.


It extends too far for the normal behaviour of a depression, It can not amintain a compressed  or is that a decompressed core.


To fill a space that reaches from the same longitude as Iceland to that of the BAltic requires extensive decompression.

Where could all that lack of pressure come from?


More importantly  where did it all go?
It joined forces with the other Low and disappeared?


Elongation implies a mixed air mass is making it up. It has to separate out as the original anticyclone degasses. They are showing up as separated warm and cold fronts.

It is a volcanic signal but how did it generate?
Obviously there had been a tornadic spell enmeshed further back up the trail. So it is also a forecast of that.
