Sentences with phrase «oceans gyre circulation»

Hatun et al. also used altimeter data (local sea level height measurements from satellite observations) to diagnose the norther oceans gyre circulation.

Not exact matches

The pattern the water circulation forms in that region is called the Indian Ocean Gyre, one of five of the major ocean gyres of the world that scientists have identified soOcean Gyre, one of five of the major ocean gyres of the world that scientists have identified soocean gyres of the world that scientists have identified so far.

Where the poleward & equatorward currents of this intensified circulation converge — the centre of the gyres — surface water is pumped downwards into the ocean interior in a process known as Ekman pumping.

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.

After I read the Hatun et al paper I thought the major point of the paper was that ocean circulation and the subpolar gyre is an important but little understood factor in the THC and more research in the area was needed.

Given that the answer to this for atmospheric models is a resounding «NO» (particularly because of sub-grid scale processes which need to be effectively pre-ordained through parameterizations), and given that oceanic circulations have much longer adjustment time scales, yet also have much more intense small scale (gyre) circulations than the atmosphere, my instinct is that we are not even close to being able to trust ocean models without long term validation data.

In the northern hemisphere the land masses prevent this and the ocean circulation is broken into smaller gyres in the Atlantic and Pacific basins.

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 Oocean 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 OceanOcean.

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

Some of the warm water would be subducted by Atlantic Meridional Overturning Circulation / Thermohaline Circulation, some would be carried by ocean currents into the Arctic Ocean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade wocean currents into the Arctic Ocean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade wOcean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade winds.

We study this low - frequency variability of the winddriven, double - gyre circulation in mid-latitude ocean basins, via the bifurcation sequence that leads from steady states through periodic solutions and on to the chaotic, irregular flows documented in the observations.

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.

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.»

Gyre - Basin - scale ocean horizontal circulation pattern with slow flow circulating around the ocean basin, closed by a strong and narrow (100 - 200 km wide) boundary current on the western side.

In this paper, it is shown that coherent large - scale low - frequency variabilities in the North Atlantic Ocean — that is, the variations of thermohaline circulation, deep western boundary current, northern recirculation gyre, and Gulf Stream path — are associated with high - latitude oceanic Great Salinity Anomaly events.

Computer models have shown the slowing and speeding up of the subpolar gyre can influence the entire ocean circulation system.»
