Not only has the AMOC slowed down (Cunningham et al [2013]-RRB-, but sea surface temperatures in North Atlantic subpolar gyre have begun falling, as have sea surface temperatures in the North Pacific subtropical gyre - best illustrated by the Pacific Decadal Oscillation (PDO) being strongly positive this year.

However the negative NAO also implies a spin - down of the subtropical gyre and therefore a drop in the pole - ward transport of warm tropical waters.

«We are already seeing this in the North Atlantic subtropical gyre, and this is some of the first evidence for climate damping the ocean's ability to take up carbon from the atmosphere.»

A study called Floating marine debris surface drift: Convergence and accumulation toward the South Pacific subtropical gyre [PDF] also suggests that this gyre is a closed loop, and that the garbage that enters it doesn't leave, which could be the cause of not seeing so much debris floating.

This basin wide, clockwise flow is referred to as the Subtropical Gyre.

My understanding is that's the subtropical gyre right?

Thus, the subtropical gyre circulation is a horizontal circulation with poleward mass transport along the western boundary, and equatorward transport everywhere east of that, and providing no net northward mass transport integrated across the basin (which is what Bryden et al have done).

This seems like it's going to keep tropical waters hotter and thus promote more hurricanes (in agreement with what Gray says (if one interprets his statements as referring to the portion of the atlantic circulation — the subtropical gyre — that delivers more warm water to the tropics).

In 2004, more of the northward Gulf Stream flow was recirculating back southward in the thermocline within the subtropical gyre, and less was returning southward at depth.

So, firstly, their findings don't support your speculation that changes in the wind - driven subtropical gyre might explain the observed tropical Atlantic SST warming.

[Response: The classical (i.e. Stommel) theory of the subtropical gyre requires that the interior equatorward (Sverdrup) transport that takes place everywhere but a narrow strip along the western edge of the basin, precisely balance the poleward transport that takes place in a narrow boundary current along the western edge of the basin.

Such materials are hardly impermanent — as the vast garbage patch drawn into the North Pacific Subtropical Gyre makes clear — but as sculptural media they are fragile.

The patch is in an area of ocean between California and Hawaii called the North Pacific Subtropical Gyre — a kind of swirling dead end for Pacific currents, which have been depositing floating plastic trash there for decades.

They had just completed the third leg of the first expedition ever to study plastic pollution in the South Atlantic subtropical gyre.

If you trawl a fine mesh net through any of the globe's five subtropical gyres — giant ocean vortexes where currents converge and swirl unhurriedly — you will haul on deck a muddle of brown planktonic goop, the occasional fish, squid or Portuguese man - of - war — and, almost certainly, a generous sprinkling of colourful plastic particles, each no larger than your fingernail.

CSIC researcher Carlos Duarte, coordinator of the Malaspina Expedition, states: «Our results show that the high concentration of plastic is not a unique feature of the Nort Pacific, but occurs in each of the subtropical gyres.»

In an email chat, Yair Rosenthal of Rutgers University and Braddock Linsley of Columbia University, whose related work was explored here in 2013, said the Argo analysis appeared to support their view that giant subtropical gyres are the place where heat carried on currents from the tropics descends into the deeper ocean.

It seems to us quite possible that the capacity of the deeper oceans to absorb heat has been seriously underestimated, especially that of the intermediate waters of the subtropical gyres lying below the mixed layer and above the main thermocline.

Alternatively, if a deepening of the subtropical gyres gives rise to an increase in the heat stored in this water mass, with a corresponding non-zero trend in the surface heat flux; then I should think that a restoration towards conditions of the past must somehow give rise to a delayed warming of the atmosphere (if the surplus is not somehow lost to space).
