Oceanography was a job that i hoped would turn into a life long career but family issues forced me to change my path in life but i still follow all i can on the subject.

I don't believe the AMOC will stop like some doom sayers mention but even a small reduction in the flow will and i believe already has begun to change the weather in the UK.

Differences globally but 2000 is the most similar recent year for the Atlantic SST pattern..

Nice spot SB. Interesting how it's so similar globally (allowing for overall warming of the Pacific) yet pretty much a complete reverse in the vicinity of the UK 🤔.

Some of that could be down to ice melt possibly. We know that in a lot of years the North Pacific looks absurdly cold for few weeks on the anomolies but it usually clears itself up (obviously looks worse in -PDO years).

I would also add for those who believe the Met Office's May SST-Winter NAO link, this is a horrifically awful pattern. The exact opposite tripole to what we want.

I see I still have some reach. :D

I do have in plan to do a post on Atlantic with some more data, like different depths and also salinity anomalies. Might also add a cross-section or two. All from the well respected datasets MERCATOR and UKMOs GloSEA5.

The area where hurricanes form has cooled a fair bit in the last week

As things stand it looks like we are headed for a cold Atlantic full stop.

Not a bad thing in removing the +NAO tripole somewhat.

To do a quick update. Atlantic subsurface temps are below average just like the surface ones.

    thetao_in_Met_O_GLO_PHYS_dm_TEM_15330367       thetao_in_Met_O_GLO_PHYS_dm_TEM_15330356  

 

And a cross section by latitude over Atlantic at 20W and 30W for Juney showing that cooler waters are not just near the surface.

Nice charts.

The grey areas on the cross section charts = missing data?
