Sentences with phrase «driven gyres»

a) The wind driven gyre fills the entire basin (between the rapid western boundary current and the slower southward returning currents in the rest of the Atlantic), and extends vertically down to the top of the NADW.

Gray doesn't refer to the wind - driven gyre circulation in his comments, he specifically refers to the thermohaline circulation.

We must distinguish between the wind - driven gyre circulation and the thermohaline - driven meridional overturning circulation.

The GS is a wind driven gyre of relatively high velocity.

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.

Not exact matches

1) «Cold Spot» is mainly driven by Wind - Forcing over the SPG (Subpolar - Gyre), which is deepens the mixed Layer and cause upwelling of colder Water.

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.

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.

But if you want a very rough idea... (others will no doubt correct me) then the wind - driven circ ends up being a large gyre, which concentrates into a narrow current along the western boundary, with a much broader return in the rest of the basin — William]

It's clear that THC does» nt drive the entire GS (I never said it), there are, as Gavin said it, loops and gyres which have a great participation in the heat transfer.

And I do think there are a number of questions about interpretation of observations, and the details of the climate model experiment (the very large exponentially increasing freshwater fluxes, the low - resolution of the ocean which obscures the potentially important role of wind - driven ocean gyres, etc.).

I also have a hard time understanding how the Gulf Stream — the western boundary current of the North Atlantic gyre — would weaken much under global warming, as it is driven by a physical process, gyre circulation, amplified by the presence of the coastline: http://oceanmotion.org/html/background/western-boundary-currents.htm

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.

Many of the surface currents of the world oceans (i.e., the ocean «gyres» which appear as rotating horizontal current systems in the upper ocean) are driven by the wind, however, the sinking in the Arctic is related to the buoyancy forcing (effects that change either the temperature or salinity of the water, and hence its buoyancy).

Manucharyan, G., M. A. Spall, and A. Thompson, 2016: A theory of the wind - driven Beaufort Gyre variability.

What if the climate shifts to cooler conditions in the next climate shift due in a decade driven by UV / ozone chemistry, polar surface pressure and sub-polar gyres in amplifying a dimming sun.

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

The main mechanism for wind - driven mixing into the deep ocean (down to around 2000 metres) is via convergence of warm tropical surface water in the subtropical ocean gyres.

For example, the Beaufort High — an extension of the Siberian High system — is a pressure system that drives the anticyclonic motion of the Beaufort Gyre.

The future evolution of ENSO will be determined by the strength of the South Pacific gyre — that in turn is driven by surface pressure at the South Pole and resultant changes in circumpolar westerly winds.

When the tropical easterly trade winds strengthen, as they have from the year 2000 onwards, this whole wind - driven ocean circulation becomes more vigorous, the South Pacific subtropical gyre spins up, and the western arm of the gyre exports more tropical water through the Indonesian archipelago into the Indian Ocean.

Roemmich et al (2007) suggest that mid-latitude gyres in all of the oceans are influenced by decadal variability in the Southern and Northern Annular Modes (SAM and NAM respectively) as wind driven currents in baroclinic oceans (Sverdrup, 1947).

The active wind - driven ocean circulation should have drawn down a lot of extra heat into the ocean via the subtropical gyres.

This subtropical gyre of warm North Atlantic Central Water is the hub of the energy that drives the North Atlantic circulation.

More or less upwelling in the eastern Pacific is linked to changes in wind and gyre circulation — in both hemispheres — driven by changes in surface pressure in the polar annular modes.

These changes in turn drive the decadal fluctuations of the North Pacific Gyre Oscillation.

Mid-latitude winds blow from west to east and drive the pole - ward side of the gyre.

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.

The westerlies of middle latitudes and the trade winds of the tropics drive the most prominent features of ocean surface motion, large - scale roughly circular current systems elongated in the east - west direction known as gyres.

Our results confirm that runoff is an important influence on the Arctic Ocean and establish that the spatial and temporal manifestations of the runoff pathways are modulated by the Arctic Oscillation, rather than the strength of the wind - driven Beaufort Gyre 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.

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.
