Sentences with phrase «gyre transporting»

A negative SAM spins up the South Pacific gyre transporting cold Southern Ocean water north and facilitating upwelling on the Peruvian coast.

minus 2 degrees Celsius, has protected the shelf from the inflow of water masses that are 0.8 degrees warm, which the Weddell Gyre transports along the edge of the continental shelf (see graphic).

Ultimately if the freshwater melt was a dominant (which seems hard to believe given the scale of the wind - driven gyre transport) factor, it would be entrained into the gyres at the surface and you'd see an overall freshening of North Atlantic surface waters to make the whole system more like the Pacific, which has a much weaker meridional overturning circulation.

The AHT and the transport in the oceanic gyres are positively correlated, because the gyre transport responds to the atmospheric winds, so militating against long - term variability involving the wind - driven flow.

Not exact matches

[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.

This is to be expected because the spin - up of the wind - driven ocean circulation speeds up the currents (Ekman transport) which carry heat out of the tropics in the near - surface layers toward the subtropical ocean gyres.

Thus this isobar gradient is able to have a far larger impact on the total transport through the broad eastern side of the gyre than it is on the very narrow western side of the gyre.

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).

Ekman transport may be confined to the surface layers, but when the circulation spins up, the greater rotational speed of the gyre increases the rigidity of the Taylor column at its centre.

Conceptually, it's hard to see how the Gulf Stream western boundary current could be weakened by conditions around Greenland; this is a fluid dynamics system, not a mechanical «belt»; a backup due to less deep water formation should have little effect on the physics of the gyre and the formation of the western boundary current, and it also seems the tropical warming and the resulting equator - to - pole heat transport are the drivers — but perhaps modulation by jet stream meandering is playing some role in the cooling?

In addition, it's hard to say how the wind - driven Atlantic gyre (whose western intensification drives the Gulf Stream's transport of warm salty water northward) will affect a weakened northern end of the AMOC.

Rob Painting: The transport of heat down into the surface to deep ocean occurs via the subtropical ocean gyres.

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.

This is counteracted by decreased freshwater import associated with gyre and diffusive transports.

The amount of warm water entering the Irminger Current is particularly limited because the sub-Polar gyre also shunts the pole - ward transport to the east towards the Barents Sea.

What follows next depends on the winds — and factoring in Ekman transport — driving the north and south Pacific Ocean gyres.

Surface water is transported to the subtropical gyres because of the winds drag on the sea surface.

Note that there is also poleward transport in the shallow currents at the western edge of each subtropical ocean gyre - known as western boundary currents.

Cumulative ice motions for April — July 2008 derived from drift buoys indicate the overall transport of ice out of the Beaufort Sea around the Beaufort Gyre to the central Arctic was actually much stronger than in 2007, but it appears to be converging (motion is slowing) over the Amundsen and Nansen Basins.

Coastal and equatorial upwelling bring an enormous amount of DIC to the surface, with subsequent transport to the gyres of the open ocean, causing declines in open ocean surface pH at rates that are much faster than possibly attributed to atmospheric diffusion.

It has been noted in a five - member multi-model ensemble analysis that, associated with the changes in temperature of the upper ocean in Figure 10.7, the tropical Pacific Ocean heat transport remains nearly constant with increasing greenhouse gases due to the compensation of the subtropical cells and the horizontal gyre variations, even as the subtropical cells change in response to changes in the trade winds (Hazeleger, 2005).

They found that, in the model, the striking SPNA decadal trend reversal from 1994 - 2004 to 2005 - 2015 arose largely from variable heat transports by the ocean's midlatitude horizontal gyre circulation.

Driven by the long - term average winds in the subtropical highs, Ekman transport causes surface waters to move toward the central region of a subtropical gyre.

This transport produces a broad mounding of water as high as 1 m (3 ft) above mean sea level near the center of the gyre (Figure 6.5).

Waters moving in the western boundary currents adjacent to the major gyres (North and South Pacific and Atlantic basins and the Indian basin) transport large quantities of heat poleward from the tropics.

Transport of surface waters toward the western boundary of the ocean basins causes the ocean - surface slope to be steeper on the western side (versus eastern side) of a gyre (in either hemisphere).

Precipitation in the Desert Southwest correlates significantly with solar irradiance lagged 3 and 5 years, which suggests a link with ocean - water temperature anomalies transported by the Equatorial Countercurrent as well as the North Pacific Gyre.

I believe a lot of the confusion stems from readers not understanding how the oceans really operate - Coriolis Effect, ocean gyres, Ekman transport, and so on.

Stronger downward transport of water mass must be balanced by upwelling somewhere else, and this occurs in regions of divergence (Ekman suction)- along the equatorward travelling arms of the gyres, and along the equator itself.

We find that the energy transport associated with wind - driven ocean gyres is closely coupled to the energy transport of the midlatitude atmosphere so that, for example, the heat transport of both systems scales in approximately the same way with the meridional temperature gradient in midlatitudes.
