Major North Atlantic Upwelling!

[Dogmudgeon]

It's from an Accu-Weather meteorologist's blog, but the follow in question (Brett Anderson) doesn't strut around with a RW chip on his shoulder, either.

"From my experience, the sudden flip from warmer than normal to much cooler than normal is not that unusual, but seeing such a large chunk of the northwestern Atlantic changing in one week seems to be. "

1. Um, whoa.

We're talking changes of up to 10 - 12 degrees Fahrenheit in the water temperature in some of those places.

:wtf: is going on here?

Edited for bad math.

2. Isn't this one of the nightmare senarios?

Where a large freshwater arctic ice melt cools and desalinates the northern Atlantic, which in turn interrupts the trade currents/gulf stream.

[Warpy]

4. It is, and the Gulf Stream has been slowing dramatically

which is how it was all supposed to start.

Gonna be a bumpy ride, kids, if this isn't just a temporary glitch.

3. OK, what's up with that? can we expect weather changes from such

an event???

:shrug:

[GCP]

5. Oh oh

That kind of thing could shut down the Gulf Stream according to one of the theories I read.

6. Somebody call in Harrison Ford

Cheney needs a slap down before the snow starts to fall.

Oh and send some more tea, bisquits and whiskey to that Hobbit guy in Scotland, will ya?

[demnan]

7. Didn't they just have snow in Buenes Aires

for almost the first time ever?

8. can you give us the link on this? thanks

[Dogmudgeon]

15. Great Scot! (And here's The Missing Link.)

Don't *I* feel like a monkey!

I hereby apologize for my negligence. I am usually so diligent with the linkage.

The link: LINK <== Link

9. I hope someone w/ better understanding than I have

can discuss this here. The graphs are frightening.

10. Where is the safe word?

somebody tell me the fucking safe word.

11. If it is an upwelling from the depths, that's just nice strong salt water - GOOD.

If it's lots of cold fresh meltwater from Greenland and the Arctic, then it's FRESHWATER, very low in salt, and is a big worry for shutting down the currents.........

12. Link to current map

Not getting any better.

14. Rather see the Actual SST than "Anomaly" report

Seeing the Atlantic and all of the Great lakes suddenly show a sharp change in the SST anomaly analysis. Which also just happens to occur at the change of a month, leaves me a bit skeptical about what the images are saying. It is definitely suspect that the Base data from which the anomaly is calculated is not consistent between the two images.

On Edit: Checked the data from Geoges Bank Buoy (170NM NE Hyanis MA)
which visually on the subject image appears to have cooled.
June 27 average water temp 11.5C
July 4 average water temp 12.9C

16. I don't think this is the face of disaster

It's Yet Another Weather Anomaly, like the snowstorm in BA yesterday, or the heat waves in both North America and Europe this summer.

Someone (Kestrel, I think?) mentioned that this is high-salt water, a factor that would discourage thermohaline interruption. But until we see actual salinity data, we won't know for sure. On the other hand, experience tells us that it is likely to be more salty than the ambient seawater. And on the third hand, if that, too, is anomalous, it would mean it's a freshwater upwelling.

Welcome to the end of the Quaternary Era and the start of the Ohshiternary Era.

17. you're not kidding!

Welcome to the end of the Quaternary Era and the start of the Ohshiternary Era.

18. According to this map the sea around Greenland is quite warm

This may or may not be a good thing overall, but it would seem to indicate that the cooling in the more southerly portions of the Atlantic isn't being caused by glacial melt. Thank the FSM for small mercies.

[Dogmudgeon]

19. It looks like the same data set

And the strong northern Pacific temperature anomalies have appeared again. This is starting to look like a long-term change in the currents of the northern Pacific basin, although I would double-check with an oceanologist or even an experienced sailor. That area is also a big thermohaline upwelling area.

20. Blistering heat in the southern Prairies of Canada once again

Blistering heat in the southern Prairies once again

Here are two of the hotter temperatures that I spotted as of late Friday afternoon......

UPDATE!!!!!!! Onefour, Alberta......41 celsius or 106 F !!!!!!!

Val Marie, Saskatchewan.....38 celsius or 100 F
